Embodiment Construction

[0031] The technical solution provided by the present invention is: when the user starts to search for channels, first adopt the full-frequency point search mode, and search for NIT in the process, once an effective NIT is found, record the frequency value of the channel containing NIT to In the memory, and then directly locate to the specified frequency point according to the NIT to quickly search for stations. After the channel search is completed, each time you turn on the TV system, since the TV system has recorded the frequency point where the NIT is located, you can first go to the specified frequency point to obtain the NIT and check its version. If there is an update, quickly search for a channel and update the program list.

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be un...

Abstract

The invention is suitable for all-in-one digital televisions, in particular provides a method for searching channels of an all-in-one digital television. The method is characterized by comprising the following steps: a, adopting a full frequency point mode to search channels, searching an NIT from a TS flow of the channels and turning to the step b if an effective NIT exists or else continuously adopting the full frequency point mode to search the channels; and b, extracting and trimming frequency list descriptors from the NIT to obtain a frequency list comprising various channel frequency values and setting the frequencies of a tuner into a frequency in the frequency list one by one for rapidly searching the channels. The invention provides the technical scheme so that the all-in-one digital television can not only rapidly search the channels and shorten the waiting time of users, but also can realize the function of automatically upgrading the program list and effectively improve the satisfaction degree of the users.

Description

technical field [0001] The invention belongs to the technical field of televisions, and in particular relates to a channel searching technology for a digital television integrated machine. Background technique [0002] Digital TV is being promoted all over the country and will eventually replace analog TV. However, due to history and national conditions, digital TV operators in various cities and regions have not entered this field under completely unified standards and regulations. PSI The transmission forms of / SI (Program Specific Information / Service Information, program definition information / service information) are not exactly the same, including the placement frequency and organization form of these information may also be different. Even the PSI / SI of digital TV signals sent by different operators in the same city may be inconsistent. [0003] Because the existing business model of digital TV all-in-ones is similar to ordinary flat-screen TVs, manufacturers tend to ...
