Technical Field

The invention relates to the technical field of network set top boxes, in particular to a system and a method for realizing that a mobile terminal plays a satellite low-bit-rate live broadcast program.

Background

With the high-speed development of the internet and the continuous promotion of the intelligent process, the television set top box is gradually developed from a digital set top box to a network intelligent set top box, the functions of the television set top box are also gradually upgraded from the initial analog signal conversion to the digital signal and the high-definition film source playing to internet video on demand, APP application software downloading, three-screen fusion (a television screen, a computer screen and a mobile phone screen), man-machine interaction and the like. The network intelligent set-top box can watch video contents directly through the Internet, and is richer in contents compared with the contents provided by traditional cable television operators, so that the network intelligent set-top box is favored by users; however, in the field of remote areas, due to poor network signals, the mobile terminal is often in a weak networking state, internet resources cannot be accessed, and live television programs cannot be watched due to the absence of an independent display device.

disclosure of Invention

The invention aims to provide a system and a method for realizing that a mobile terminal plays a satellite low-bit-rate live program, which are used for solving the problems that the mobile terminal cannot access resources and cannot watch a television live program because no display equipment exists in the prior art.

The invention solves the problems through the following technical scheme:

A system for realizing mobile terminal playing satellite low-bit-rate live broadcast programs comprises a satellite live broadcast set top box and a mobile terminal, and comprises: the satellite live broadcast set-top box comprises:

Tuner1, which is used to receive the live program and decode and transmit, and is responsible for the frequency-locked playing of the normal satellite live program of the set-top box;

Tuner2, which is used to receive the low-bit rate live broadcast and request program and decode and transmit, and is responsible for the frequency locking of the distribution of the low-bit rate live broadcast program and request program;

the DTV is used for receiving the live program of the Tuner1 and transmitting the live program to the television through an HDMI channel, and is also used for receiving the low-bit-rate live program and the on-demand program of the Tuner2, storing the low-bit-rate live broadcast information and the on-demand information to a database, and storing the low-bit-rate live broadcast slice and the on-demand data to a built-in hard disk of the satellite live broadcast set-top box;

And the mobile terminal acquires data of a built-in hard disk and a database through a WiFi module of the satellite live broadcast set top box and watches the live broadcast program with low code rate.

The WiFI module is composed of a WiFi sub-board (comprising a gigabit network port and a hundred-megabyte network port) arranged in a satellite live broadcast set top box, and on-demand programs are stored in a built-in hard disk and are used for being distributed to a client side of a mobile terminal.

a set of web services of THTTPD + CGI + SQLite is deployed on a satellite live broadcast set top box system, an application APP matched with the satellite live broadcast set top box is installed on a mobile terminal, and a low-bit-rate live broadcast program and an on-demand program can be watched on a live broadcast module of the application APP.

Further, the WiFi module is also in communication connection with a public network server or in communication connection with the public network server through a 4G module. The satellite direct broadcast set-top box adopts a 4G module of the whole network.

A method for realizing a mobile terminal to play a satellite low-bit-rate live program comprises the following steps:

step S100: building the system for realizing the mobile terminal to play the satellite low-bit-rate live program;

Step S200: when the satellite live broadcast set top box is started, Web service of THTTPD + CGI is started, HTTP network interfaces related to description information of satellite live broadcast programs are deployed, and WIFI hotspot information is shared;

step S300: the satellite live broadcast set top box starts live broadcast program search under a user instruction, searches parameters of a live broadcast program and a live broadcast program, wherein the parameters comprise origin NetWokID (initial network ID), TransportStreamID (TS stream ID), ServiceID (service ID) and the like, and starts to lock frequency, analyze and descramble the live broadcast stream according to the parameters;

step S400: the satellite live broadcast set top box starts an REC tool to start recording streams and sends out live broadcast streams in a Socket form;

step S500: starting an FFmpeg tool by the satellite live broadcast set top box, preparing slicing, starting to receive live broadcast stream data sent by Socket in the previous step, starting slicing, and forming a low-bit-rate live broadcast program after slicing; writing the low-bit-rate live program and the on-demand program into a built-in hard disk;

Step S600: the satellite live broadcast set-top box writes the description information of the low-code-rate live broadcast program into an SQLite database,

step S700: the mobile terminal is connected with the WiFi hotspot, an application APP which is installed on the mobile terminal and is matched with the satellite live broadcast set top box is opened, and a live broadcast module of the application APP is entered to watch the low-bit-rate live broadcast program and the on-demand program.

A method for playing a satellite low-bit-rate live broadcast program by a mobile phone based on a satellite live broadcast set top box system solves the problem that users without internet signals, such as motor home users and army field training camp users, cannot watch real-time live broadcast television programs; except that utilizing traditional large screen TV to watch live program, also can use the smart mobile phone of oneself to connect local area network and watch real-time little code rate live program, the cell-phone watches the little code rate live program that live star STB distributes, because the satellite live STB supports a plurality of mobile terminals to connect simultaneously, solved large screen and shows that everybody can only watch the problem of a channel at the same time, the cell-phone user can select the program that oneself wanted to watch wantonly, and mutual noninterference, provide convenience for the user.

Compared with the prior art, the invention has the following advantages and beneficial effects:

(1) The invention realizes the technology that mobile terminals such as mobile phones and the like play the satellite low-bit-rate live programs based on the satellite live broadcast set top box system, and realizes that a plurality of people watch real-time low-bit-rate television live programs on line at the same time.

(2) the mobile terminal and the satellite direct broadcast set top box are communicated through the WiFi module, and flow and cost are not generated.

(3) The mobile terminal can be communicated with the public network server through the wifi module and the 4G module of the satellite direct broadcast set top box to obtain resources, and flow and cost are not generated in the whole process.
