If Dolby Digital control 704 or Dolby Digital Plus control 705 is selected by the user, the display device will output the Dolby sound effect format. What dolby sound format output can satisfy the surround sound of full range, can promote user's audio experience. However, it should be noted that if the media source format is Dolby Digital, although the display device supports Dolby Digital output format, if the user does not manually set the display device, the display device still defaults the Digital audio output format to PCM format, and the external device can only play the sound effect in PCM format. It is noted that, if the automatic recognition mode control 701 is selected by the user, the display device may automatically recognize the most suitable digital audio output format in combination with the decoding capability of the external device and the film source format, without manual setting by the user.

When a user performs manual setting, because the user may have a situation that the Digital audio output format is unknown or the media resource format is unknown, when the user enters a Digital audio output format setting interface, the user may have a wrong selection situation, for example, because the user does not know the meanings represented by the PCM control 703, the Dolby Digital control 704 and the Dolby Digital Plus control 705, and the user does not know the Digital audio output format of the media resource, the user arbitrarily selects the PCM control 703 as the Digital audio output format, and actually the Digital audio output format of the media resource is Dolby Digital, the user cannot accurately match the Digital audio output format and the media resource format of the display device, which causes a manual setting error, thereby affecting the sound effect experience of the user.

Therefore, the existing method for setting the digital audio output format option as the default PCM format by the display device has the problem that the user does not perform manual setting or sets the setting by hand incorrectly, which affects the sound effect experience of the user.

In order to solve the technical problem, according to the display device provided by the application, the digital audio output format option is defaulted to the automatic identification mode, so that when the display device is successfully connected with the external device, the display device determines the digital audio output format transmitted to the external device by the display device by acquiring the decoding capability parameter of the external device and the film source format of media resources, the problem that a user does not set or manually sets the digital audio output format transmitted to the external device by the display device in error can be avoided, and the user experience is improved.

If the digital Audio output format option defaults to a PCM format and the display device outputs the digital Audio output format through ARC, the digital Audio output format supported by the external device is not considered at this time, and when the media resource format is a dolby format, a dolby panoramic sound format, a binaural PCM format, an Advanced Audio Coding (AAC) format, or a High Efficiency Advanced Audio Coding (High Efficiency Advanced Audio Coding) format, the digital Audio output format supported by the external device is a binaural PCM format because the digital Audio output format option defaults to the PCM format, and when the media resource format is a DTS format, the digital Audio output format supported by the external device is a PCM format. If the user does not perform manual setting or the manual setting is wrong, the PCM or dual-channel PCM format sound effect can be only experienced through the external equipment.

According to the method and the device, the digital audio output format option is defaulted to be the automatic identification mode, and when the display device outputs the digital audio output format through the ARC, the digital audio output format supported by the external device to be played can be determined by acquiring the decoding capability parameter of the external device. The digital Audio output formats referred to below, such as Dolby compressed Audio format (Dolby Audio compression ion 4Dolby-AC4), MAT, Dolby lossless Audio format (Dolby TrueHD), etc., are all existing digital Audio output formats, and will not be explained in detail.

If the external device supports a digital audio output format of MAT2.x, when the media source format is Dolby-AC4, DD, Dolby TrueHD, MAT or a combination of a plurality of slice source formats, the external device supports a playing digital audio output format of MAT2.x or Multi-channel PCM (Multi-channel PCM); when the media resource format is Dolby-AC4, DD, Dolby TrueHD, MAT or the combination form of a plurality of film source formats, the digital audio output format supported by the external equipment for playing is MAT2.x or panoramic sound; when the media resource format is a dual-channel PCM format, the digital audio output format supported by the external device for playing is MAT2.x or dual-channel PCM (2 chPCM); when the media resource format is AAC/HEAAC format, the digital audio output format supported by the external device to play is MAT2.x or PCM.

If the external device supports the digital audio output format to be DDP panoramic sound but not MAT2.x, when the media resource format is Dolby-AC4, DD, Dolby TrueHD, MAT or the combination of a plurality of film source formats, the external device supports the played digital audio output format to be DDP; when the media resource format is Dolby-AC4, DD, Dolby TrueHD, MAT or the combination form of a plurality of film source formats, the external equipment supports the played digital audio output format to be DDP panoramic sound; when the media resource format is a dual-channel PCM format, the external equipment supports the DDP of which the played digital audio output format is a 2.0 version; when the media resource format is AAC or HEAAC format, the digital audio output format supported by the external device to play is DDP.

If the external device supports the digital audio output format to be DDP but does not support DD panoramagram and MAT2.x, when the media resource format is Dolby-AC4, DD, Dolby TrueHD, MAT or the combination form of a plurality of film source formats, the external device supports the played digital audio output format to be DDP; when the media resource format is Dolby-AC4, DD, Dolby TrueHD, MAT or the combination form of a plurality of film source formats in Dolby panoramic sound format, the digital audio output format supported by the external equipment for playing is DDP; when the media resource format is a dual-channel PCM format, the external equipment supports the DDP of which the played digital audio output format is a 2.0 version; when the media resource format is AAC or HEAAC format, the digital audio output format supported by the external device to play is DDP.

If the external device supports a digital audio output format of MAT2.x, when the media resource source format is Dolby-AC4, DD, Dolby TrueHD, MAT or a combination form of a plurality of film source formats, the external device supports a played digital audio output format of MAT2.x or multichannel PCM; when the media resource format is Dolby-AC4, DD, Dolby TrueHD, MAT or the combination form of a plurality of film source formats, the digital audio output format supported by the external equipment for playing is MAT2.x or panoramic sound; when the media resource format is a dual-channel PCM format, the digital audio output format supported by the external equipment for playing is MAT2.x or dual-channel PCM; when the media resource format is AAC or HEAAC format, the digital audio output format supported by the external device to be played is MAT2.x or PCM.

If the external device supports the digital audio output format DD but does not support MAT2.x and DDP, when the media resource format is Dolby-AC4, DD, Dolby TrueHD, MAT or the combination of a plurality of film source formats, the external device supports the played digital audio output format DD; when the media resource format is Dolby-AC4, DD, Dolby TrueHD, MAT or the combination form of a plurality of film source formats in Dolby panoramic sound format, the external device supports the played digital audio output format to be DD; when the media resource format is a dual-channel PCM format, the external equipment supports the played digital audio output format to be DD of a 2.0 version; when the media asset source format is AAC or HEAAC format, the digital audio output format supported by the external device to play is DD.

If the external device does not support the digital audio output formats DD, DDP, and mat2.x, when the media resource formats are the dolby format, the dolby panoramic sound format, the binaural PCM format, the AAC format, the HEAAC format, and the DTS format, the digital audio output formats that the external device supports playing are the binaural PCM format.

When the media resource format is a DTS format, if the external device supports the DTS format, the digital audio format supported by the external device for playing is a DTS format, and if the external device does not support the DTS format, the digital audio format supported by the external device for playing is a PCM format.

It can be seen from the above embodiments that, compared with the prior art that the digital audio format item is defaulted to the PCM format by default in the automatic identification mode, the digital audio output format is richer in the manner shown in the present application.

An embodiment of the present application shows a display device, including: a display; an external device interface, such as an HDMI interface or an optical fiber interface, for accessing an external device; a controller for performing the following steps shown in FIG. 8:

step S801: and after the display equipment is powered on, monitoring whether the external equipment is successfully connected.

In some embodiments, the external device includes a bluetooth speaker, a power amplifier, and other audio devices. The HDMI or the optical fiber interface on the external device display device is accessed to the display device, for example, the HDMI or the optical fiber line of the external device is inserted into the display device, the display device transmits a connection signal to the external device, and the external device receives the connection signal and establishes a connection relationship with the display device.

Step S802: and when the external equipment is successfully connected, acquiring decoding capability parameters of the external equipment, wherein the decoding capability parameters are used for representing the decoding capability of the external equipment.

Step S803: and when the media assets are played, determining a digital audio output format transmitted to the external equipment by the display equipment according to the decoding capability parameters and the film source format of the media assets.

Decoding is a process of restoring a digital code to the content it represents in a particular way. The transparent transmission is a transmission mode which transmits the transmitted content from a source address to a destination address without changing the data content. When the display equipment is connected with the external equipment, the display equipment transmits a Digital audio output format to the external equipment through an HDMI (high-definition multimedia interface) line or an optical fiber line in a Digital signal mode, the capability of the external equipment for receiving the Digital signal and reducing the Digital signal into the Digital audio output format is decoding capability, for example, the media resource format is Dolby Digital, when the display equipment transmits the Dolby Digital format to the external equipment through the HDMI line in the Digital signal mode, the external equipment receives the Digital signal, and if the external equipment can reduce the Digital signal into the Dolby Digital format, the external equipment supports playing the Dolby Digital format; if the external device cannot restore the Digital signal to the Dolby Digital format, the external device does not support playing the Dolby Digital format.

In one implementation, the digital audio output format that the external device supports playing comprises: DD. DDP, MAT. The digital audio output format supported by the external device is the decoding capability parameter of the external device.

In the actual application process, there are various ways to monitor whether the external device is successfully connected. For example, the display device monitors whether the external device is successfully connected through a Consumer Electronics Control (CEC) service.

The CEC service is a complete set of one-wire bus protocols by which a display device can control all HDMI-connected devices on an HDMI interface and allow HDMI devices to command each other without user intervention. The HDMI includes a CEC bus and an Audio Return Channel (ARC) Channel, where the CEC bus is a general control bus used for interconnection of HDMI devices. The ARC channel is used for outputting digital audio of a television, can be connected with an external device which also supports the ARC function, and transmits sound of the display device to the external device.

In one implementation, the display device monitors whether the external device is successfully connected through the CEC service. And after the external equipment is powered on, the display equipment is accessed through the external device interface, the CEC service is loaded, and when the external equipment does not receive any instruction, the standby mode is entered. As shown in fig. 9, the display device controller performs the following steps:

step S901: the CEC service is loaded.

In the scheme shown in this embodiment, the display device supports the CEC service, and after the display device is powered on, the CEC service is directly loaded and used for managing all devices connected to the HDMI.

Step S902: and acquiring the external equipment information on the CEC bus through the CEC service.

In some embodiments, the CEC service includes a device lookup module and an acquisition module, and the device lookup module is configured to lookup external device information on a CEC bus to facilitate connection between the display device and the external device. When the external device information is found, the acquisition module acquires the external device information, wherein the external device information comprises an external device name, an external device manufacturer and an external device plug-in interface. Through acquiring the information of the external equipment, the user can know the name of the external equipment, the manufacturer of the external equipment and the insertion interface of the external equipment, and the user can manage the external equipment conveniently.

Step S903: and when the information of the external equipment is acquired, waking up the power amplifier of the external equipment.

In some embodiments, when the external device information is acquired, the display device does not send any instruction to instruct the external device to respond, and when the external device does not receive any instruction, the external device enters a standby mode. When the external device is in the standby mode, the display device sends a power amplifier awakening instruction to the external device, the external device responds to the power amplifier awakening instruction of the display device at the moment, the external device enters a starting state, and the external device awakens the power amplifier. By adopting the implementation mode, the power amplifier is awakened when the external device is in the power-on state, so that other instructions sent by the display device can be conveniently received. If the external device does not wake up the power amplifier, when the display device sends another instruction, for example, an sad (short Audio descriptor) instruction is sent to obtain the decoding capability parameter of the external device, the external device may not respond because it is in a standby state.

Step S904: and when the power amplifier of the external equipment is awakened successfully, sending an ARC handshake instruction.

In some embodiments, the ARC may send the display device media asset audio to an external device without deactivating an on-board speaker of the display device. The display device establishes connection with the external device by sending the ARC handshake command, and is used for sending the audio from the ARC port to the external device.

Step S905: and when the response of the external equipment to the ARC handshake instruction is received, carrying out ARC handshake with the external equipment.

Step S906: and when the handshake with the external equipment is successful, determining that the connection of the external equipment is successful.

In some embodiments, the external device receives the ARC handshake instruction sent by the display device, enters an ARC handshake waiting state, and reports that the display device is in the ARC handshake waiting state in response to the ARC handshake instruction sent by the display device. And after receiving the ARC handshaking instruction responded by the external equipment, the display equipment carries out ARC handshaking with the external equipment.

In one implementation manner, when the display device acquires the information of the external device, the display device may send the ARC handshake instruction, and if not, the display device may send the ARC handshake instruction after waking up the power amplifier of the external device successfully. The sending of the ARC handshake instruction may also be at other points in time. The embodiment includes, but is not limited to, setting the sending of the ARC handshake instruction to be performed after successfully waking up the external device. The ARC handshake sending instruction is set to be successfully sent after the power amplifier of the external device is awakened, so that a better technical implementation effect can be achieved.

In one implementation, the controller is further configured to:

when the handshake with the external equipment is successful, controlling to display a first prompt message and/or play a first voice message on the display, wherein the first prompt message and the first voice message are used for prompting a user that the external equipment is successfully connected;

and when the response of the external equipment to the ARC handshake instruction is not received or the handshake with the external equipment fails, controlling to display a second prompt message and/or play a second voice message on the display, wherein the second prompt message and the second voice message are used for prompting a user that the connection of the external equipment fails.

In some embodiments, fig. 10 illustrates a schematic diagram of a first prompting message shown in the embodiment of the present application, and as shown in fig. 10, the first prompting message is in the form of an image. When the display device is successfully connected with the external device, the display device controls the display to display a first prompt message image for informing a user that the external device is successfully connected.

In one implementation, the second prompting message is in the form of a sound. When the display device is not connected with the external device or the connection fails, the display device controls the internal speaker to emit a prompt sound, for example: and the device connection failure is used for informing the user that the external device is not connected or the connection fails.

In one implementation manner, when it is monitored that the external device is successfully connected, before the acquiring of the decoding capability parameter of the external device, the method further includes:

acquiring the on-off state of an automatic identification mode;

and if the automatic identification mode is in an open state, acquiring the decoding capability parameter of the external equipment.

In some embodiments, the display device is in the auto-id mode state when the auto controls of the digital audio output format setting interface are in the activated state.

It should be noted that, in the scheme shown in this embodiment, the display device defaults the digital audio output format to the automatic control, so that the display device may directly acquire the state of the automatic recognition mode without entering the digital audio output format interface to manually select the automatic control.

In some embodiments, when the display device is connected to the external device, the display device plays the media assets or does not play the media assets.

In one implementation, the controller is further configured to:

when media assets are played, if the external equipment is monitored to be accessed, and when the external equipment is monitored to be successfully connected, a media asset source format is acquired;

and determining a digital audio output format transmitted to the external equipment by the display equipment according to the media resource format and the decoding capability parameter of the external equipment.

In one implementation manner, when a display device plays a media asset, if a CEC service monitors that an external device is accessed, after ARC handshake connection is successfully performed, a media asset source format is obtained through an Audio Package information bit (Audio Package information bit), where the media asset source format is Dolby Digital as an example, and the obtained media asset source format is Dolby Digital; in one implementation, the decoding capability parameter of the external device includes: dolby Digital, Dolby Digital Plus; and determining that the Digital audio output format transmitted to the external equipment by the display equipment is Dolby Digital according to the media resource format and the decoding capability parameter of the external equipment.

It should be noted that, the display device defaults the digital audio output format on the automatic control, when the display device plays media resources, the external device is connected, the display device can directly acquire the automatic identification mode state without manual setting, when the display device is in the automatic identification mode state, the display device can directly send a CEC command to acquire the decoding capability parameter of the external device, and when the external device receives the CEC command sent by the display device, the external device reports the decoding capability parameter.

In one implementation, the controller is further configured to:

if the external equipment is successfully connected, acquiring a media asset source format when an input media asset playing instruction is received;

and determining a digital audio output format transmitted to the external equipment by the display equipment according to the media resource format and the decoding capability parameter of the external equipment.

In one implementation manner, when it is monitored that the external device is successfully connected, the display device may acquire the decoding capability parameter of the external device, but at this time, because media resources are not played, it is impossible to determine the digital audio output format transmitted to the external device by the display device. When an input media asset playing instruction is received, a media asset source format is obtained through an audio packet information bit, and a digital audio output format transmitted to the external equipment by the display equipment is determined according to the media asset source format and decoding capability parameters of the external equipment. Since the matching relationship between the media asset source format and the digital audio output format supported by the external device has been described in the foregoing embodiments, no further description is given here.

In one implementation, the controller is further configured to:

and responding to an input instruction for indicating to display a loudspeaker setting interface, and controlling to display the loudspeaker setting interface on the display, wherein the loudspeaker setting interface at least comprises a first item and a second item, the first item is used for identifying an audio output mode, the second item is used for setting the digital audio output format, and the second item is also used for identifying the currently set digital audio output format or an automatic recognition mode.

In some embodiments, the first item is an audio output control, the second item is a digital audio output format control, and clicking on the audio output control can enter an audio output setting interface, where the audio output setting interface at least includes: the ARC control and the display device built-in speaker control. Clicking on the digital audio output format control may enter a digital audio output format interface that includes at least an automation control and a PCM control, but is not limited to the controls described above.

It should be noted that, the display device defaults the digital audio format output format on the automatic control, and may still perform manual setting to select other controls. Such as PCM controls, Dolby Digital controls, and the like.

In one implementation, the controller further includes:

when the external equipment is successfully connected, controlling the display to display that the first item identification audio output mode is ARC and the second item identification digital audio output format is an automatic identification mode;

when the external equipment is monitored to be failed in connection or not connected, controlling the display to display the first item identification audio output mode on the display as a display equipment built-in loudspeaker, and displaying the second item grey for identifying that the second item cannot be set.

Fig. 11 is a schematic diagram illustrating a speaker setup interface 1100 output by an embodiment of the application. As shown in fig. 11, the speaker setting interface 1100 includes an Audio Output (Audio Output) control 1101, a Digital Audio Output format (Digital Audio Output) control 1102, a Digital Audio Delay (Digital Audio Delay) control 1103, a Lip synchronization (Lip Sync) control 1104, a Balance (Balance) control 1105 and an enhanced Audio return channel (eARC) control 1106, where when it is detected that the external device is failed to connect or not connected, the Audio Output control 1101 identifies that the Output mode is the display device internal speaker, and the Digital Audio Output format 1102, the Digital Audio Delay control 1103 and the enhanced Audio return channel control 1106 are all set to be grey. Although the digital audio output format control 1102 is grayed out, its flag is set on the automatic recognition mode.

Based on the above embodiments, the present application exemplarily shows a possible display device compatibility method, including:

after the display equipment is powered on, monitoring whether the external equipment is successfully connected;

in one implementation manner, the method for monitoring whether the external device is successfully connected includes:

and receiving the ARC handshake instruction responded by the external equipment to carry out ARC handshake.

When the external device is successfully connected, acquiring decoding capability parameters of the external device, wherein the decoding capability parameters are used for representing digital audio output formats supported by the external device, and the decoding capability parameters are used for determining the digital audio output formats transmitted to the external device by the display device.

In one implementation mode, if it is monitored that the external equipment is successfully connected when the media asset is played, acquiring a film source format of the media asset;

and determining a digital audio output format transmitted to the external equipment by the display equipment according to the film source format of the media resources and the decoding capability parameter of the external equipment.

In one implementation mode, if the connection success of the external equipment is monitored when the media assets are not played, when an input media asset playing instruction indicating the playing of the media assets is received, a film source format of the media assets is obtained;

and determining a digital audio output format transmitted to the external equipment by the display equipment according to the film source format of the media resources and the decoding capability parameter of the external equipment.

It should be understood that specific implementation manners of each step in the display device compatible method may refer to the foregoing display device embodiments, and are not described herein again. According to the display device and the display device compatible method, when the display device is successfully connected with the external device, the display device determines the digital audio output format transmitted to the external device by the display device through acquiring the decoding capability parameter of the external device, so that the problem that a user does not set or manually sets the digital audio output format transmitted to the external device by the display device in error can be avoided, and the user experience is improved.
