In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for the convenience of description of the present application, and have no peculiar meaning by themselves. Thus, "module", "component" or "unit" may be used mixedly.

As shown in fig. 1, the present embodiment provides an IPTV multimedia playing method, which is based on a gateway device, and includes:

s110, analyzing a multimedia program playing request acquired from a client to obtain multimedia program multicast information;

s120, sending a multicast group joining request to an IPTV platform according to the multimedia program multicast information;

s130, acquiring a multicast data stream fed back by the IPTV platform aiming at the multicast group joining request;

s140, converting the multicast data stream into a data stream of a preset streaming media protocol, and sending the data stream of the preset streaming media protocol to the client; and the data stream of the preset streaming media protocol is used for being analyzed by the client, so that the multimedia program is played.

In the implementation manner, compared with the existing IPTV multimedia program playing, the set-top box is not needed, and the multimedia program playing request of the client is obtained through the gateway equipment. The client is pre-installed in the television, when a user inputs a multimedia program which the user wants to play to the television, the client generates a corresponding multimedia program playing request according to the multimedia program which the user wants to play and sends the multimedia program playing request to the gateway equipment, and the multimedia program playing request comprises multimedia program multicast information. The gateway equipment analyzes the multimedia program playing request to obtain multimedia program multicast information. The multimedia program multicast information is information for requesting an IPTV multicast video stream, and may include a multicast group address of a multimedia program and a port corresponding to the multicast group address. The gateway device can request the IPTV platform to join the multicast group according to the multicast group address and the port corresponding to the multicast group address. After joining the multicast group, the multicast data stream fed back by the IPTV platform is received. The gateway device converts the multicast data stream into a data stream of a preset streaming media protocol which can be supported by the television, and sends the data stream of the preset streaming media protocol to the client. Therefore, after the data stream of the preset streaming media protocol is analyzed by the client, the playing of the multimedia program can be realized on the television. The gateway device may be an Optical Network Unit (ONU) installed in a home environment, and as the performance of the PON chip is higher and higher, the IPTV function may be implemented by software. The functions of the gateway and the set top box are allowed to be fused, and the set top box is reduced under the condition that the functions of the set top box are realized through the gateway equipment, so that a large amount of equipment and operation and maintenance cost can be saved.

In one implementation manner, before the analyzing the multimedia program playing request acquired from the client to obtain the multimedia program multicast information, the method further includes,

receiving the multimedia program playing request sent by the client through the preset streaming media protocol;

the multimedia program multicast information is obtained by analyzing the multimedia program playing request acquired from the client, including,

and analyzing the multimedia program playing request to obtain the multimedia program multicast information.

The preset Streaming media protocols usually supported by the tv include HyperText transfer Protocol (HTTP) and Real Time Streaming Protocol (RTSP). The gateway equipment receives a multimedia program playing request of a preset streaming media protocol sent by a client, and analyzes a multicast group address and a port corresponding to the multicast group address.

In an implementation manner, the sending a multicast group join request to an IPTV platform according to the multimedia program multicast information includes:

and sending a multicast Group join message based on an Internet Group Management Protocol (IGMP) to the IPTV platform according to the multimedia program multicast information.

The gateway device can send a multicast group join message to the IPTV platform to request to join the multicast group after analyzing the multicast group address and the port corresponding to the multicast group address, so as to obtain the multicast video stream delivered by the IPTV platform.

In one implementation manner, the acquiring the multicast data stream fed back by the IPTV platform for the multicast group join request includes:

and acquiring a multicast data stream based on a User Datagram Protocol (UDP) fed back by the IPTV platform.

Wherein, after joining the multicast group of the multimedia program, the multicast data stream fed back by the IPTV platform is received. Generally, the multicast data stream fed back by the IPTV platform is based on User Datagram Protocol (UDP).

In an implementation manner, the converting the multicast data stream into a data stream of a preset streaming media protocol and sending the data stream of the preset streaming media protocol to the client includes:

caching the multicast data stream;

reading the multicast data stream and converting the multicast data stream into a data stream of the preset streaming media protocol;

and sending the data stream of the preset streaming media protocol to the client.

After receiving the UDP multicast data stream, the UDP multicast data stream is placed in a cache of the gateway device. Then, the PON chip core sending process of the gateway device reads multicast stream data (UDP) from the cache and converts the multicast stream data (UDP) into a data stream of a preset streaming media Protocol, and sends the data stream of the preset streaming media Protocol to the client, for example, reads the multicast stream data (UDP) and converts the data stream into a data stream of TCP (Transmission Control Protocol).

In an implementation manner, before the converting the multicast data stream into a data stream of a preset streaming media protocol and sending the data stream of the preset streaming media protocol to the client, the method further includes:

judging whether the acquired multicast information of the multicast data stream is matched with the multicast information of the multimedia program;

and under the condition that the multicast information of the multicast data stream is matched with the multicast information of the multimedia program, converting the multicast data stream into a data stream of a preset streaming media protocol and sending the data stream to the client.

The gateway device receives the multicast data stream and then judges the multicast data stream to determine whether the multicast information of the multicast data stream, namely the multicast group address of the multicast data stream and the port corresponding to the multicast group address are the same as the multimedia program multicast information of the multimedia program playing request. If the multicast information of the multicast data stream is the same as the multicast information of the multimedia program, the multicast information of the multicast data stream is considered to be matched with the multicast information of the multimedia program; and if the multicast information of the multicast data stream is different from the multicast information of the multimedia program, the multicast information of the multicast data stream is not matched with the multicast information of the multimedia program. And when the multicast information of the multicast data stream is matched with the multicast information of the multimedia program, converting the multicast data stream into a data stream of a preset streaming media protocol and sending the data stream to the client. The situation of playing errors under the condition of a plurality of multimedia program playing requests is avoided.

In an implementation manner, after the converting the multicast data stream into a data stream of a preset streaming media protocol and sending the data stream of the preset streaming media protocol to the client, the method further includes:

receiving multimedia program closing information sent by the client;

sending a multicast group leaving request to the IPTV platform according to the multimedia program closing information;

and deleting the multimedia program playing information configured locally.

After the client finishes playing the multimedia program, or the user inputs the information that the playing of the multimedia program is stopped to the client without watching the current multimedia program. The multimedia program closing information is information that the playing of the multimedia program is finished and acquired by the client, or information that the playing of the multimedia program is stopped and input by the user. The client sends the closing information of the multimedia program to the gateway equipment, and the gateway equipment requests the IPTV platform to leave the multicast group according to the closing information of the multimedia program. That is, the multicast group leaving message is sent to the corresponding multicast group and port, and all the multimedia program playing information configured locally is deleted, thereby releasing the related resources. Therefore, the resources of the gateway equipment can be released in time, and the load of the gateway equipment on the operation caused by the occupation of the gateway equipment is avoided.

In one implementation, as shown in fig. 2, the gateway device is configured with a streaming media protocol parser, a multicast stream broker, a kernel receiver, a kernel transmitter, and a buffer; the gateway device is respectively connected with a DLNA (Digital Living Network Alliance) television and an IPTV platform, IPTV multimedia is played in the implementation mode, a set top box is not required to be configured, redundant devices are reduced, and cost is reduced.

The streaming media protocol parser, the multicast streaming proxy, the kernel receiver and the sender are functionally distinct software processing modules. The streaming media protocol analyzer is responsible for carrying out streaming media protocol interaction with the client to acquire a playing request of the client; the multicast stream agent is responsible for requesting the multicast stream of the specified multicast group and port; the kernel receiver stores the appointed multicast data stream into the buffer, and the kernel sender takes out the multicast stream from the buffer, converts the multicast stream into a TCP stream and sends the TCP stream to the client. The cache size can be configured according to the size of the memory, so that the effect of balancing resources and time consumption is achieved.

In one implementation, as shown in fig. 3, the ONU is a PON upstream gateway device, a DLNA television and a mobile Terminal are hung under a WLAN (Wireless Local Area Network) port of the ONU, a WAN (Wide Area Network) port of the ONU is connected to an OLT (Optical Line Terminal) through an Optical fiber, and an OLT upstream port of the OLT is connected to servers of a plurality of IPTV platforms. The steps of the mobile terminal, the DLNA television, the ONU and the IPTV platform shown in fig. 3 for implementing IPTV multimedia program playing are as follows:

1. a user selects a played multimedia program through a control client on the mobile terminal and sends the multimedia program to the DLNA television;

2. the DLNA television requests a corresponding video file from the ONU through a streaming media protocol (such as HTTP/RTSP), wherein a multicast group address and a multicast port are carried to the ONU; for example: http://192.168.136.1:8888/udp/225.1.1.1.1:1111, wherein 225.1.1.1 denotes a multicast group address and 1111 denotes a multicast port number;

3. the ONU analyzes the request message through a streaming media protocol analyzer to obtain a multicast group address and a port;

4. the ONU requests a corresponding multicast data stream from the IPTV platform through the multicast stream agent;

5. the IPTV platform sends a corresponding multicast data stream according to the multicast group join message;

6. the ONU kernel receiver firstly judges whether the multicast data stream is a multicast data stream requested before, and puts the multicast data stream into a buffer under the condition that the multicast data stream is the multicast data stream requested before;

7. the ONU kernel transmitter converts the multicast data stream (UDP) into a video stream (TCP) and forwards the video stream (TCP) to the DLNA television;

8. and the DLNA television analyzes the video stream (TCP) and plays the multimedia program.
