Problems solved by technology
[0003] Every intelligent display terminal will be equipped with a channel search function, and when performing a channel search, it will scan frequency bands, for example, every 8MHz, and some frequency bands are empty, that is, there is no channel, and sometimes a channel is scanned. It takes 5 seconds, and the current smart display terminal has as few as 30 channels, and as many as hundreds, which will lead to a long overall channel search and scan time, and the scan speed is very slow
In the case of more and more channels in the smart display terminal, more and more time and system resources are occupied by searching channels, and the scanning efficiency is very low, which greatly reduces the user experience

Embodiment Construction
[0138] In order to make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0139] In today's society, smart display terminals represented by TV are the most influential mass media, and with the development of society, the competition among operators of various local channels is becoming increasingly fierce. Operators at all levels, whether from the central or local levels, have made great adjustments in order to cope with fierce competition. The number of channels has increased sharply. important prerequisite for development.
[0140] Therefore, operators in provinces, cities, and even counties and towns, in order to further meet the audience's cultural needs, often make regional adjustments to channels, such as reducing channels that are not valued such a...

An embodiment of the present invention provides a channel search method for an intelligent display terminal, the method comprising: the intelligent display terminal sends a channel search request to a network device; the channel search request includes the network address of the intelligent display terminal; the A channel mapping table is preset in the network device, and the channel mapping table includes one or more regional information and corresponding frequency point information; the network device is used to determine the region to which the intelligent display terminal belongs according to the network address information, and extract the frequency point information corresponding to the region information from the channel mapping table; the intelligent display terminal receives the frequency point information returned by the network device, and uses the frequency point information to directly locate the channel. The accuracy of the frequency information is improved by locating the frequency point information through the geographical information; the channel is directly positioned through the frequency point information, which avoids scanning blank frequency bands, reduces the overall time and system resource occupation of searching for channels, and improves the efficiency of searching for channels.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of smart display terminals, and in particular, relate to a channel search method for a smart display terminal, a channel search device for a smart display terminal, and a device. Background technique [0002] With the development of society, in order to meet people's further demands on the quality of life, the functions of intelligent display terminals tend to be intelligent, and the number of broadcast and TV channels of intelligent display terminals is increasing, and the programs of the channels are becoming more and more diverse. [0003] Every intelligent display terminal will be equipped with a channel search function, and when performing a channel search, it will scan frequency bands, for example, every 8MHz, and some frequency bands are empty, that is, there is no channel, and sometimes a channel is scanned. It takes 5 seconds, and the current intelligent display terminal has as...
