In the first embodiment, the television program playing method includes:

Step S10: Obtain a TV signal code stream corresponding to the currently played program in the recording mode, and store the TV signal code stream.

When the television terminal plays the program through the digital television signal, the television signal stream is obtained from the digital signal, and the television signal stream is a TS stream (Transport) Stream, transport stream), TS stream is to package video, audio and other data into transport packets for transmission, mainly for program transmission. Therefore, the current broadcast program has a corresponding TS stream, and the TS stream corresponding to the current broadcast program is acquired and stored. The complete TS stream may be obtained for storage, stored in the hard disk according to the user's requirement, or stored in the memory of the television end. Further, each program has a corresponding PID code (Packet Identifier, the identifier of the data packet, because the acquired TS stream is a continuous stream of code, and may contain multiple TV programs. Therefore, it is necessary to acquire and store the corresponding TV signal stream according to the PID code of the currently broadcasted program. In an embodiment, the complete TS stream may be segmented according to the duration of the currently played program or the duration set by the user.

It can be understood that if the user cannot watch the live program but wants to see the TV program through the terminal, the television terminal starts the recording mode after receiving the code stream acquisition instruction by sending the code stream acquisition instruction on the terminal. , the TV signal stream of the currently playing program can be obtained and stored. In addition, the television end can also determine whether the user has left the live program cannot be viewed by detecting the status of the connection between the TV end and the terminal. If the connection is disconnected, the recording mode is turned on, and the TV signal stream of the currently played program is acquired and stored. .

Step S20: Generate an event information configuration file according to the TV signal code stream, and send the event information configuration file to the server.

The digital television signal carries an event information table of the television program, and the event information table provides information such as the name of the event, the start time, the length of time, and the running status. The specific information related to the current television program in the event information table is extracted, and an event information configuration file is generated, and the format of the file may be an XML format or a format supported by other terminals. The event information profile is sent to the web server for the user to view back through the terminal based on the event information profile selection television program.

It can be understood that if a plurality of television programs are stored on the television end, the event information configuration file may include related information of a plurality of television programs.

Step S30, when receiving a program play request sent by the terminal based on the event information configuration file on the server, sending the TV signal code stream corresponding to the program play request to the terminal, for the The terminal decodes the TV signal stream and plays it.

When the user wants to look back at the program missed on the TV end on the terminal, he only needs to obtain the event information configuration file from the server, select the TV program he wants to watch according to the program information in the file, and send a play request, the television end After receiving the request, the TV signal stream of the TV program corresponding to the play request is sent to the terminal for decoding and playing, and it can be understood that the TV end sends the TV signal stream stored in the background to the terminal, and currently It can also play other TV programs without affecting the playback of TV programs on the terminal.

Further, before step S10, the method further includes the following steps:

Establishing a connection with the terminal through a multi-screen interaction technology, and transmitting a current play interface to the terminal;

Specifically, the multi-screen interaction technology realizes the transmission of digital multimedia content through a wireless network connection between a plurality of different terminal devices, can synchronously display content on different screens, and realize control of the terminal device through the intelligent terminal. For example, the video on the mobile phone can be played on the TV, and the live broadcast on the digital TV can be watched synchronously on the mobile phone.

The recording mode is triggered when a code stream acquisition command is received or/and the connection is detected to be disconnected.

Specifically, when the user shares the live program on the TV through the multi-screen interaction technology, if the user needs to leave or has other things and cannot watch at the time, the user can send a code stream acquisition instruction to notify the television terminal to record the program. Or the user can directly carry the terminal to leave. When the TV detects that the multi-screen interactive connection has been disconnected, the recording mode is automatically triggered.

Further, when receiving a program play request sent by the terminal based on the event information configuration file on the server, sending the TV signal code stream corresponding to the program play request to the terminal, for providing Before the step of decoding and playing the television signal stream, the method may further include the following steps:
