Problems solved by technology

[0003] Due to the large number of EPGs transmitted by the front-end network, sometimes even reaching tens of thousands, the traditional digital TV set-top box needs to receive all the EPG information for analysis to determine which data is needed and which data has been saved. As a result, receiving data is slow, especially when the user switches to the TV program for the first time, it takes a long time to display the EPG information

Embodiment Construction

[0014] To receive EPG (Electronic Program Guide) information, the set-top box is to collect the eit (event information segment) table data sent by the front-end system, analyze the content of the eit table, and obtain the program information of the TV program. In the eit table, table_id and serviceId are key fields, and their meanings are as follows:

[0015] The current / subsequent event information segment on the transport stream of this frequency point whose table_id is 0x4e;

[0016] The table_id is 0x4f, which is the current / subsequent event information segment on the transmission stream of other frequency points;

[0017] Table_id is 0x50 to 0x5f, which is the time table event information segment on the current transport stream of this frequency point;

[0018] Table_id 0x60 to 0x6f is the schedule event information segment on the current transport stream of other frequency points;

[0019] serviceId is the unique identifier for identifying a TV channel in the transport...

Abstract

The invention provides a method for a set top box to quickly receive EPG data. Different EPG data is received in a hierarchical classification mode according to a certain time sequence, so that new EPG data can be quickly acquired on a television channel which does not acquire the EPG data, or a television channel which acquires the EPG data but has updated data; and thus, the new EPG data is rapidly received and is displayed to the users in time. The invention solves the problem of slow EPG data receiving caused by massive EPG data in the network in the traditional set top box for digital televisions.

Description

【Technical field】 [0001] The invention relates to a set-top box, in particular to a method for the set-top box to quickly receive EPG data. 【Background technique】 [0002] With the rapid development of digital TV technology, more and more digital TV set-top boxes have entered the homes of ordinary people, and the electronic program guide (EPG), which is an important function of digital TV set-top boxes, has gradually become the main function of users. Provide users with detailed program information within 7 days, including the broadcast time of the program, the detailed content of the program, etc., which is convenient for users to use. Watch the desired program. EPG information is divided into two types, including the current next piece of information and 7-day detailed information, where the current next piece of information refers to the TV program information of the currently watched program at the current time and the next TV program information; 7-day detailed informa...
