Abstract
Disclosed are a logical channel number parsing method and a logical channel number parsing device. The method includes: acquiring an operator which provides program signal, and searching channels in sequence according to preset frequency points; acquiring channel information of a current frequency point, and extracting logical channel number data from the channel information, when searching channels according to each of the frequency points; and parsing the logical channel number data according to a prestored logical channel number configuration table corresponding to the operator, to obtain each of attribute parameters comprised in the logical channel number data. The present disclosure simplifies the parsing operation of the logical channel number.
Claims12
A logical channel number parsing method, wherein, the logical channel number parsing method comprises:
- acquiring an operator which provides program signal, and searching channels in sequence according to preset frequency points;
- acquiring channel information of a current frequency point, and extracting logical channel number data from the channel information, when searching channels according to each of the frequency points;
- acquiring a first bit offset and total bits corresponding to each of attribute parameters comprised in a prestored logical channel number configuration table corresponding to the operator;
- and parsing the logical channel number data according to the acquired first bit offset and the total bits corresponding to each of the attribute parameters, and determining each of the attribute parameters in the logical channel number data;
- wherein, based on different operators, the first bit offset and the total bits, corresponding to each of the attribute parameters in the logical channel number, are different.
A logical channel number parsing device, wherein, the logical channel number parsing device comprises at least one processor and a memory storing program instructions, wherein the program instructions are executable by the at least one processor to perform:
- acquiring an operator which provides program signal, and searching channels in sequence according to preset frequency points;
- acquiring channel information of a current frequency point, and extracting logical channel number data from the channel information, when searching channels according to each of the frequency points;
- and
- acquiring a first bit offset and total bits corresponding to each of attribute parameters comprised in a prestored logical channel number configuration table corresponding to the operator;
- and parsing the logical channel number data according to the acquired first bit offset and the total bits corresponding to each of the attribute parameters, and determining each of the attribute parameters in the logical channel number data;
- wherein, based on different operators, the first bit offset and the total bits, corresponding to each of the attribute parameters in the logical channel number, are different.
