Problems solved by technology
Generally, when a set-top box searches for channels, it will display all the programs that can be searched to the user for selection, but some of the scrambled programs that are not scrambled by non-cooperative network operators cannot be played normally.
In this case, the practicability of the set-top box to search channels is not high, and it may cause users to misunderstand that the set-top box has broken down, thereby affecting the sales of the set-top box

The embodiment of the invention discloses a digital television channel search method and a digital television terminal. The method comprises steps: each frequency point with a network information table (NIT) is traversed; program names of a first frequency point in the frequency points with the NITs are stored, wherein the first frequency point is the frequency point belonging to a preset network operator; program names of a second frequency point in the frequency points with the NITs are searched, the program names, consistent with the preset program names, of the second frequency point are stored, wherein the second frequency point is the frequency point not belong to the preset network operator, and the preset program names are the names of clear stream programs of other frequency points beside the current frequency point in the frequency points with the NITs; and the stored program names serve as channel search results to be presented to the user. When the embodiment of the invention is implemented, the programs searched by the user can be ensured to be played normally, practicality of channel search is improved, and digital television terminal failure can be prevented from being mistaken by the user.
Description
technical field [0001] The invention relates to the technical field of digital television, in particular to a digital television channel searching method and a digital television terminal. Background technique [0002] For digital television, a set-top box for converting digital signals into analog signal output is essential. When the set-top box searches for channels, the searched programs include scrambled programs and stream-clearing programs. Scrambling refers to the use of pseudo-random sequences to scramble and control the multiplexed program transmission stream. The scrambled programs need to be descrambled before they can be played normally; The clear stream program refers to the program that has not been scrambled. After the set-top box searches for the clear stream program, it can be played directly without descrambling. [0003] Currently, programs are scrambled in a variety of ways, and different network operators use different methods to scramble programs, but ...
