Embodiment Construction

[0070] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0071] Fig. 2 is a structural schematic diagram of the device of the present invention. As shown, including

[0072] Application layer data request module 210, when the application program displays multi-day EPG data, it will send a data request to the multi-day EPG receiving device and wait for a response.

[0073] The data receiving module 220 controls the receiver to filter the EIT SCHEDULE data segment with the specified Service ID mark from the TS stream of the data word service, and analyzes it to judge the correctness and completeness of the received data, obtain useful relevant data, and make multiple Day EPG data.

[0074] The channel management control module 230 is connected respectively with the application layer data request module and the data receiving module, and is used to control the data receiving module to receive multi-day EPG da...

Abstract

It includes: (1) the application layer data requesting module is used to send channel-switching request or multi-day EPG data of digital service request to channel-supervising module (CS); (2) the data receiving module (DR) is used to filter and receive EIT SCHEDULE data segments from the transmission flow of digital service; analyze them to obtain multi-day EPG data and save them; (3) CS is used to control DR to receive multi-day EPG data of the new frequency points after switching when it receives channel-switching request; and to obtain the requested multi-day EPG data of digital service from DR when it receives such request. This invention also proposes a method to obtain multi-day EPG data of digital TV including steps to receive and store multi-day EPG data and steps to supervise channels. It improves the efficiency of receiving EPG data and enables users to receive information of multi-day EPG of digital service from different channels without switching channels.

Description

technical field [0001] The invention relates to the field of digital television, in particular to a device and method for acquiring multi-day electronic program guide data of digital television. Background technique [0002] Digital TV multi-day EPG (Electronic Program Guide, Electronic Program Guide) brings users an intuitive TV program list, which is convenient for users to quickly find their favorite digital TV programs. At the same time, receiver developers can It expands many practical functions for users, such as timing recording, program reservation, etc. [0003] The data of multi-day EPG is provided through the EIT SCHEDULE data segment in SI. When the user controls the receiver to receive multi-day EPG data of a certain digital service (service), the receiver first needs to tune the digital signal receiver (Tuner) to the frequency point where the digital service is located. After the receiver finds a valid TS (Transport Stream, transport stream) stream on the fre...
