It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.

With the rapid development of the Internet and digital TV systems, the Electronic Program Guide (EPG) occupies a very important position in the entire system. In the process of actual application, it can provide users with functions such as program display, information browsing, and business operations. In fact, traditional digital TV has both multimedia online programs based on network data and live broadcast programs from broadcast networks. Since the signals from the broadcast network are one-way propagation and due to the limitation of frequency locking by a single high-frequency head, only the current location can be obtained. The EPG data of frequency-point broadcast programs is not conducive to the acquisition of all frequency-point program data and the management of network multimedia online programs. It is not convenient for users to uniformly select their favorite programs. Usually, to watch online programs, you have to switch to an APP to select and watch live broadcasts. Programs have to be switched to another APP to select, which brings great inconvenience to users.

In order to solve the above problems, an embodiment of the present invention provides a unified program recommendation method based on EPG. During specific implementation, this embodiment first obtains the program event data of each tuner format and the program playback of network programs when the background is in idle time. information. Then, the program event data and the program playback information are stored in a preset database in a unified EPG format to obtain EPG program data. Finally, the program content of the EPG program data in the database is presented in categories to achieve unified program recommendation. In this embodiment, the program event data of live programs and the program playback information of online programs are uniformly formatted according to the digital TV live EPG program data and integrated into a unified program information data recommendation system to facilitate users to watch programs.

Example methods

In this embodiment, the EPG-based unified program recommendation method can be applied to terminal devices, which are terminal devices that can play video programs, such as televisions, computers and other terminal products. During specific implementation, as shown in Figure 1, the unified program recommendation method based on EPG in this embodiment specifically includes the following steps:

Step S100: When the background is in idle time, program event data of each tuner format and program playback information of network programs are obtained.

During specific implementation, what this embodiment wants to achieve is to uniformly format the program event data of live programs and the program play information of online programs according to the digital TV live EPG program data, and integrate them into a unified program information data recommendation system to facilitate users to watch programs. . To this end, this embodiment will first need to obtain the program event data of each tuner format and the program playback information of the network program. As specifically shown in Figure 2, in this embodiment, the current live broadcast status is first obtained, and based on the current live broadcast status, it is determined whether the background is in idle time. If the background is in idle time, the high-frequency format is switched, and the frequency points of each format are traversed to obtain the program event data. As shown in Figure 2, when the idle condition is met, if the live broadcast is not currently being played, this embodiment can sequentially switch the current high-frequency format to the dvbt terrestrial format, dvbc cable format, and dvbs satellite format. And start to obtain the frequency point of the first program of the current format, thereby traversing the frequency points of all programs. When the frequency points of all formats are traversed, frequency lock resources are applied for, that is, all program event data of the three formats are obtained. In this embodiment, the program event data includes: channel program service id, program transmission stream id, program transmission network id, program event id, network program path indicator, live program cover image acquisition path indicator, program start time, program Duration and program name. details as follows:

The main data of program event data include the following:

In this embodiment, when the program playback information of the network program is available, as shown in Figure 3, this embodiment can request the network server to obtain the program EPG data of the current network program to obtain the program playback information.

Step S200: The program event data and the program playback information are stored in a preset database in a unified EPG format to obtain EPG program data.

In this embodiment, in order to uniformly format the program event data of live programs and the program play information of online programs according to the digital TV live EPG program data, and integrate them into a unified program information data recommendation system to facilitate users to watch programs. In this embodiment, after obtaining the program event data and program playback information, the program event data and program playback information are uniformly formatted according to the digital TV live broadcast EPG program data to obtain an EPG Database, and the EPG Database is stored in flash, as shown in Figure 2 and Figure 3. This embodiment saves the EPG Database in flash. The advantage of saving in flash is that the EPG data of all programs can be previewed immediately after booting, unlike ordinary EPG, which requires playing or switching programs before previewing the EPG data of the current frequency program. . Moreover, the EPG Database is divided into Memery memory skyepg.db with an upper limit of 10M and Flash storage skyepg.db. When EpgScan is being performed on a frequency point, the Head and Event data of the EIT are written to the memory skyepg.db, which not only improves the speed but also reduces the number of erases and writes to the Flash. In this embodiment, when a frequency point EpgScan is completed normally, EpgStaionCtrl will be notified and it will decide to synchronize it to Flash when the memory exceeds 10M. If a frequency point EpgScan is completed abnormally (timeout, frequency point switching, etc.), the downloaded data of the current frequency point will be cleared. During standby, EpgStaionCtrl will be notified to synchronize memory data to Flash, and at the same time, it will clear outdated (exceeded the current time) data in Flash in a 30-minute alignment manner.

Step S300: Classify and present the program content of the EPG program data in the database to implement unified program recommendation.

Because this embodiment will uniformly format the program event data of live programs and the program playback information of network programs according to the digital TV live EPG program data, integrate them into a unified program information data recommendation system, and combine the EPG programs in the database The data sets a unified program classification list, so that when a program needs to be played, the program classification list is loaded and presented. It is convenient for users to make reservations to watch programs and record live programs, forming a unified program management and recommendation interface, which facilitates audience identification and profiling, and personalized recommendation of program content. In addition, this embodiment also converts the EPG program data into voice data based on the text description and event long description of the EPG program data, making it convenient for visually impaired people to use and improving user experience.

To sum up, this embodiment first obtains the program event data of each tuner format and the program playback information of the network program when the background is in idle time. Then, the program event data and the program playback information are stored in a preset database in a unified EPG format to obtain EPG program data. Finally, the program content of the EPG program data in the database is presented in categories to achieve unified program recommendation. In this embodiment, the program event data of live programs and the program playback information of online programs are uniformly formatted according to the digital TV live EPG program data and integrated into a unified program information data recommendation system to facilitate users to watch programs.
