Problems solved by technology
For TVs used in special occasions, such as hotel TVs and hospital TVs, the TV channels are updated more frequently. For example, the hotel buys movies for users to watch, and the hotel TV channels need to be updated, and at the same time there will be TVs in many rooms that need to update TV channels. This requires full-channel scanning, which is time-consuming and labor-intensive, causing users to be unable to watch updated TV channels in time

The invention discloses a television channel update method and system. The method comprises the steps of searching whether first channel data required for playing a target channel is stored or not when a playing instruction for the target channel is received; obtaining pre-stored second channel data associated with the target channel when a search result is no, wherein the second channel data comprises a master channel number, a sub-channel number, a physical channel number and modulation frequency of the target channel; carrying out channel scanning according to the modulation frequency, thereby obtaining first channel data of each channel modulated by the modulation frequency; receiving a first channel data obtaining instruction, and obtaining the first channel data required for playing the target channel from the first channel data of each channel, according to the first channel data obtaining instruction, the master channel number, the sub-channel number, the physical channel number of the target channel; and playing the target channel according to the obtained first channel data. According to the method and the system, the channels can be rapidly updated without scanning all the channels, and an actual application demand is satisfied.
Description
technical field [0001] The invention relates to the technical field of digital television, in particular to a method and system for updating television channels. Background technique [0002] For traditional home digital TV, before watching TV programs, it is necessary to perform channel scanning action to search and save all TV channels. For home TV, the channels of TV are relatively fixed, and only one scan The table action is sufficient for use. For TVs used in special occasions, such as hotel TVs and hospital TVs, the TV channels are updated more frequently. For example, the hotel buys movies for users to watch, and the hotel TV channels need to be updated, and at the same time there will be TVs in many rooms that need to update TV channels. In this way, full-channel scanning is required, which is time-consuming and labor-intensive, resulting in the user being unable to watch updated TV channels in time. Contents of the invention [0003] Based on the above situation...
