Embodiment Construction

[0039] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] see figure 1 , figure 1 It is a flow chart of a method for searching channels of a digital TV according to the first embodiment of the present invention. The method for searching channels of the digital TV specifically includes:

[0041] Step S101, searching for program information corresponding to the address according to the address where the digital TV is located;

[0042] Step S102. Obtain the data packet of the program information from the network server, and the data packet of the program information includes one or more of the following data: NIT, SDT, EIT, TOT.

[0043] Further, in the method for searching channels of digital TV in the above-mentioned first embodiment, after obtaining the data packet of the program information from the network server, the following processing is also included: readin...

Abstract

The invention discloses a digital television and a channel searching method thereof. The method comprises the following steps: according to an address of location of the digital television, searching program information corresponding to the address; acquiring a data packet of the program information from a network server, wherein the program information data packet comprises one or more kinds of the following data: a network information table (NIT), a service description table (SDT), an event information table (EIT) and a TOT. By using the digital television and the channel searching method thereof, after the needed address is searched, the data packet of the program information corresponding to the address can be directly acquired from the network server. A frequency point corresponding to the needed address does not need to be searched. Through analyzing the data packet of the program information corresponding to the address acquired by the frequency point, a television program corresponding to the address can be played. Therefore, channel searching time of the digital television can be substantially shortened and a channel searching efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of television, in particular to a digital television and a channel searching method thereof. Background technique [0002] At present, there are mainly two ways to search channels for digital TV: one is full-frequency point search, which generally searches from low frequency to high frequency sequentially. The disadvantage of this search method is that it takes a long time to search channels, which generally takes about 20 minutes. The second is to use the network information table to quickly search for channels. The second method first performs frequency point locking, and then processes such as intermediate frequency amplification and filtering to obtain PAT (Program Association Table, program association table) information, and obtains the required PMT (Program Map Table program mapping table) and PID (Packet IDdentifier, identification code transmission packet) information, and finally perform initializ...
