Embodiment Construction

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0040] At present, the indexing and navigation of various services provided by IPTV are completed through the Electronic Program Guide (EPG) system. The EPG information is divided into basic EPG information and extended EPG information. The basic EPG information is described by the SI information table.

[0041] In practical applications, the SI table needs to be inserted into the TS...

Abstract

The invention provides an EPG information control device which comprises a receiving module, a storage module and a control module. The receiving module is configured to receive timing information andstatus information corresponding to each TS stream output port respectively. The memory module is used for storing the EPG information sent by the external equipment. A control module is respectivelyconnected with a receiving module and a storage module. At preset interval, the timing information corresponding to each TS stream output port is sequentially detected, For each TS stream output port, if it is detected that the EPG information corresponding to the starting address reaches the transmission time, A TS stream output port is judged to be in an idle state according to that state information, If the TS stream output port is in an idle state, the EPG information is inserted into the TS stream output by the TS stream output port, thereby alleviating the technical problem that the user in the prior art cannot watch the TV program in time, and achieving the technical effect that the user can watch the TV program in time.

Description

technical field [0001] The invention relates to the technical field of radio and television, in particular to an EPG information control device. Background technique [0002] Electronic program guide (EPG for short) means electronic program menu. The indexing and navigation of various services provided by IPTV are completed through the electronic program guide system. The EPG information is divided into basic EPG information and extended EPG information. The basic EPG information is described by the SI information table. [0003] In practical applications, the SI table needs to be inserted into the TS stream for transmission at regular intervals. However, due to the inability to accurately control the transmission time of the SI table, the decoder cannot receive the SI table information in time, and thus cannot distinguish and decode various data of multiple programs in the TS stream. Users cannot watch TV programs in time. Contents of the invention [0004] In view o...
