Embodiment Construction

[0028] The technical solution provided by the present invention is: pre-store the frequency points carrying NIT in different areas and the corresponding relationship with the area in the digital TV, when the user searches for channels, select the area where the digital TV is located, and the system will The corresponding relationship between the frequency point carrying the NIT and the area, find the frequency point carrying the NIT corresponding to the area selected by the user, and then directly search for the frequency point to obtain the NIT.

[0029] 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 understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] At present, the frequency points of TV prog...

Abstract

The invention provides a digital television channel searching method and a digital television employing same, which are suitable for the technical field of digital televisions, wherein the method comprises the following steps of: a) seeking a frequency point which carries an NIT (Network Information Table) and corresponds to a zone selected by a user; and b) searching the frequency point, receiving the television signal of the frequency point, and acquiring the NIT from the received television signal. The technical scheme provided by the invention ensures that the frequency point carrying theNIT can be directly searched when digital television channel searching is carried, can realize rapid channel searching and is easy to operate and convenient to use, a user is unnecessary to input frequency point data.

Description

technical field [0001] The invention belongs to the technical field of digital television, and in particular relates to a method for searching digital television stations and a digital television adopting the method. Background technique [0002] At present, there are two ways to search channels for digital TV: one is full-frequency point search (sequential search from low frequency to high frequency), and its disadvantage is that the search time is too long; the second is to search only NIT (Network Information Table network information table). The method of only searching for NIT can be subdivided into two forms: one is to search for frequency points sequentially, and when a frequency point with NIT is found, capture NIT; the other is to let the user input the desired frequency through a menu page The searched frequency point information (such as: frequency, symbol rate, modulation method) with NIT, the TV will search for the frequency point specified by the user accordin...
