Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] In digital TV, all information and signals, including video, audio, text, pictures, etc., are digitized and become data. Before transmission, the data must be packaged according to relevant standards (usually MPEG-2) to form fixed-length transport (TS) packets. MPEG-2 TS packets are 188 bytes long, and then quickly transmitted to the destination through the network. For these TS packets with the same length, if there is no guide information, the decoder at the receiving end cannot find the required code stream. Therefore, PSI is specifically defined in MPEG-2. The role of PSI is to automatically set up and guide the decoder to decode.

[0021] PSI consists of Program Association Table (PAT), Conditional Access Table (CAT), Program Mapping Table (PMT) and Network Information Table (NIT). Each table is divided into several segments and mapped (tr...

Abstract

The invention discloses a method for obtaining digital television program guide, aiming at solving the technical problem that users can scan the digital television program information more conveniently. In order to solve the technical problem, the invention comprises the following steps: (1) the digital television initializes event information sheet space in a storage; (2) the digital television receives the basic television program guide of the digital television broadcast from a network, obtains complete SI information in the basic television program guide transport stream, obtains event information table data in the SI information and stores the event information sheet data in the event information sheet space of the storage; (3) the digital television decrypts the current video information data according to the current or subsequent program of a certain time period of the current program in the event information sheet and stores the decrypted current video information data in the space; and (4) a user turns on the digital television program guide and displays the digital television program guide on a display.

Description

technical field [0001] The invention relates to the application field of digital TV, in particular to a method for acquiring a digital TV program guide. Background technique [0002] Existing digital program guides such as figure 1 As shown, there is a corresponding relationship between the video thumbnail image and the TV program list, which channel you choose can only watch the corresponding video thumbnail image, and it is impossible for the user to browse other channel programs while watching the program image of channel 1 in the same user interface preview information, and it is also impossible to browse program detailed information at the same time, and browse multiple sets of program preview information in parallel. Contents of the invention [0003] The purpose of the present invention is to provide a method for acquiring a digital TV program guide, and the technical problem to be solved is to enable users to browse digital TV program information more conveniently...
