[0112] 1) In the first embodiment, the acquisition module 10 includes:

[0113] An acquisition unit, configured to acquire a search frequency point based on the currently received code stream information when a non-standard channel search instruction is detected;

[0114] The processing unit is configured to use the obtained search frequency points that do not match the pre-stored standard frequency points as non-standard frequency points.

[0115] In this embodiment, the code stream information received by the TV set includes a frequency point information table, and the frequency point information table includes all channels contained in the current TV signal (the TV signal corresponds to a TV operator such as a cable TV) Corresponding frequency point information, the frequency point information is the search frequency point, the obtained search frequency point may partially overlap with the standard frequency point, and the non-standard frequency point is obtained by compari...

Abstract

The invention discloses a television channel searching method. When a non-standard channel searching instruction is detected, a non-standard frequency point corresponding to the currently used television signal of a television is acquired. After that, the acquired non-standard frequency point is inserted into preset standard frequency points, so that a searching frequency point set is generated. All searching frequency points in the searching frequency point set are invoked in turn for the channel searching operation, wherein the difference between at least one pair of adjacent frequency points in the searching frequency point set is smaller than the difference between adjacent frequency points of preset standard frequency points. The invention also discloses a television channel searching system. According to the technical scheme of the invention, the channel searching operation of a television is enabled based on standard frequency points and non-standard frequency points at the same time. Therefore, the channel missing probability of the television during the channel searching process can be reduced.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a method and system for searching channels for televisions. Background technique [0002] Existing TV sets can receive more and more TV channels, and the signal frequency of some TV channels may be adjusted irregularly. After the signal frequency of the TV channel is adjusted, the TV set needs to perform channel search operation again. [0003] Existing channel search operations generally include fast channel search and full-frequency point search. Quick channel search is based on the transmission information described in the network information table in the main frequency point defined by the operator. The search method first searches the main frequency point , save the frequency point information in the frequency point network information table, and the frequency point of subsequent search will be carried out sequentially according to the frequency point information in the ...
