Background technique

IPTV, Internet Protocol Television, is a new technology that uses broadband cable TV network and integrates Internet, multimedia, communication and other technologies to provide home users with a variety of interactive services including digital TV. technology. Users can enjoy IPTV services in two ways at home: (1) computer; (2) network set-top box + ordinary TV. It can well adapt to the rapid development trend of today's network and make full and effective use of network resources. IPTV is not only different from traditional analog cable TV, but also different from classic digital TV. Because both traditional and classic digital TV have the characteristics of frequency division system, timing, and one-way broadcasting; although classic digital TV has many technical innovations compared with analog TV, it is only a change in the form of the signal, without touching the content of the media. Propagation mode.

IPTV is to use computer or set-top box STB (set top box) + TV to complete functions such as receiving video-on-demand programs, video broadcasting and surfing the Internet. It adopts high-efficiency video compression technology, so that the video streaming bandwidth can have a viewing effect close to DVD when the video streaming bandwidth is 800Kb/s (usually the video streaming bandwidth of DVD needs 3Mb/s). In Internet TV, the transmission of broadcast programs is delivered through the IP network carrying TS (Transport Stream), and on-demand programs are requested to be delivered through the TCP/IP protocol. IPTV has strong advantages for the development of video services in the future, such as live video broadcasting on the Internet, long-distance real video on demand, and program source production.

The emergence of EPG (Electronic Program Guide) in digital TV has made it convenient for users to inquire and watch programs. At present, the main function of program reservation in digital TV is to pre-book TV programs that have not yet been broadcast. When the broadcast time of the TV program that the user likes to watch has not yet arrived, the "program reservation" function can be used to make a reservation. The advantage is that the user does not need to wait on the channel if he wants to watch a complete segment of his favorite TV program, and the automatic reminder function will not delay the user's watching. In the prior art, there is a method for realizing TV program reservation in a digital TV system, as shown in Figure 1, the method for program reservation in a digital TV system, this method is to realize broadcast TV program reservation and timing play technology in a digital TV system, The main content includes: receiving the electronic program guide, obtaining the transport stream, the list of TV stations and program information, setting the timing clock; displaying the program information list, and the user saves the selected program information into the scheduled program list; setting the processing method of the scheduled time ; Check the clock cycle, and process accordingly when the scheduled program time arrives.

As mentioned above, it can be seen that the prior art is aimed at the reservation of broadcast TV programs, and does not involve in the reservation of non-broadcast programs; The processing situation that the end time of a program lags behind the start time of the next program is not taken into account; the time point of playback cannot be intelligently adjusted based on the single start time point. However, fluctuations in the end time of broadcast programs with a fixed broadcast time will affect the automatic broadcast time of scheduled programs later.

Embodiment two:

Refer to the program reservation and play process shown in Figure 4. Proceed as follows:

1. When the system is turned on, the program reservation and playback device on the set-top box displays the program reservation interface;

2. The program reservation and program list maintenance module of the playback device automatically searches for the relevant attributes of the program in the program information database, and reflects them in the program list; the user selects the program to be watched by the user through the EPG (including broadcasted broadcast time points fixed Programs, on-demand programs with unfixed broadcast time points, etc.); in combination with the user's selection, the program list maintenance module of the program reservation and playback device fills in the time (broadcast program) and related attributes of the program in the program list. options, and finally form the user program list;

3. The storage module of the program reservation and playback device stores the list of programs; the program reservation and playback device searches for the interface file in the specified path, and the display module of the program reservation and playback device displays the program reservation system interface on the display according to the set options;

4. The query module of the program reservation and playback device judges whether there is a scheduled program to be played, and when it is judged that there is a program to be played, turn to 5, and when there is no program to be played, continue to inquire. There are two conditions for discrimination, one of which is satisfied:

4.1 The query module of the program reservation and playback device cyclically searches the time information stored in the program list in the storage module of the program reservation and playback device, and judges whether the time point has arrived; after the time point arrives, it is handed over to the program reservation and playback device for processing Module processing; and/or record the program time at the front of the time point, constantly judge the arrival of the time of the machine clock, after the time point arrives, it will be processed by the processing module of the program reservation and playback device, and re-record the program reservation and playback The program time at a point in time in the program list in the storage module of the device.

4.2 The query module of the program reservation and playback device inquires that the new program is set to be played after the previous program is finished. At the same time, it is judged whether the current program is over.

1) When the current service program finishes playing, the data in the event information table EIT in the SI (service information service information) sent by the server changes, that is, the event of the program playing completion is added to the EIT table (given the current program The service ID, event ID, and the name and description information of the event given by the event descriptor); when the client receives the SI information, the SI manager finds the change of the SI information, and notifies the query of the event of the change in the SI information module. After the query module learns about this event, it can obtain the message that the previous program has been played through the service ID, event ID, and event name.

2) When the current service is an on-demand program, there is an optional method, that is, the query module determines whether the current program is over, and when the current program ends, it is handed over to the processing module for processing. The query module knows the end of the program by obtaining the message of completion of the program sent by the server.

5. After the query module of the program reservation and playback device determines that there is a program to be played, it informs the processing module of the program reservation and playback device, and the processing module of the program reservation and playback device performs related processing procedures according to the set program information, as shown in Figure 5 The detailed steps are as follows:
