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] The present invention provides a logical channel number parsing method, referring to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the logical channel number parsing method of the present invention.

[0041] In this embodiment, the logical channel number parsing method includes the following steps:

[0042] Step S10, obtain the operator that provides the program signal, and perform channel search operations in sequence according to the preset frequency points;

[0043] As we all know, different operators provide program signal content for terminals such as digital TVs and digital TV set-top boxes in different countries and regions, and there are even multiple operators in some regions. The content of the program signals provided by different operators is different. The different ...

Abstract

The invention discloses a logical channel number analysis method, comprising the following steps: acquiring an operator providing program signals, and orderly performing a channel search operation according to preset frequency points; while performing the channel search operation according to each frequency point, acquiring channel information of the current frequency point, and extracting logical channel number data from the channel information; and analyzing the logical channel number data according to a pre-stored logical channel number configuration table corresponding to the operator, and acquiring each attribute parameter contained in the logical channel number data. The invention also discloses a logical channel number analysis device. With the method and the device provided by the invention, analysis operations for the logical channel numbers are simplified.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a logical channel number analysis method and device. Background technique [0002] Different operators in different countries and regions provide channel programs for terminals such as digital TV and digital TV set-top boxes. Since each operator has its own specific logical channel number rules, different operators correspond to different logical channel number rules. When searching for a program, usually the terminal needs to analyze the logical channel number by using an analysis algorithm that matches the logical channel number rules corresponding to the operator. Therefore, for different operators, different analysis algorithms must be used, resulting in logical channel number The parsing operation is complex. Contents of the invention [0003] The main purpose of the present invention is to provide a logical channel number analysis method and device, aiming at solv...
