Example Embodiment

[0023] The present invention makes full use of the advantages of multiple Tuners. When a user is watching a program, an additional Tuner is used to realize physical channel traversal in the background to achieve the purpose of updating EPG information, such as figure 2 Shown.

[0024] The part shown in the dashed box 21 is the part provided by the present invention. The part outside the dashed box 21 is mainly the user's normal operation of watching the program, and figure 1 The functions of the system shown are the same. Users can tune through the remote control, etc., and obtain the parameters needed by Tuner1 from the exchanged program. After Tuner1 is locked, the TS stream, including audio and video data and SI data, is output. After passing through the decoder, The audio and video data is decoded and output to the TV. The EIT information in the SI will also be accepted and the original data will be updated. Of course, this is only the data in the physical channel being watc...

Abstract

The invention relates to a method for realizing automatic updating of the electronic program guide of a digital television by a plurality of tuners, the method comprises the following steps; step 1, the automatic updating of the electronic program guide is started; step 2, whether redundant tuners are available to be used is judged, if yes, step 3 is executed, otherwise, the step is ended up; step 3, the redundant tuners that are available to be used traverse all physical channels and the automatic updating of the electronic program guide of the television is carried through. The invention can realize complete and real time updating of EPG information of the digital television, so as to reduce the operation of the user and provide the user with complete and effective data.

Description

technical field [0001] The invention relates to digital television, in particular to a method for realizing automatic update of digital television EPG information under multi-tuner (Tuner). Background technique [0002] EPG information is Electronic Program Guide, which is a convenient service provided by digital TV for users. EPG information is distributed in the independent physical channel event information table (EIT) table, and the update of information is collected and updated after the user tunes the channel. In the prior art, EPG features can be briefly described as follows: EPG data is placed in the EIT table in the service information (SI) information, each physical channel can contain multiple programs, and the EIT table of each physical channel includes the channel EPG data of all programs; when the user tunes the channel, the internal program of the TV will analyze the current SI information, including the EIT table. There is version information in the table to...
