Abstract
The invention discloses a kind of method of searching television network information channel, including TV set power to allow to connect and divide in the range of specified channel；The order of searching television network information channel is inputted by user；Multiple tuner par-allel channel search are started according to the order simultaneously；When multiple tuners carry out par-allel channel search, any one in the multiple tuner skips the channel being lockable, and continues to carry out channel search to remaining channel；In searched channel frequence, detect that at least one which includes the step of the channel of TV network information and broadcast singal channel.The present invention utilizes parallel search, accelerates search procedure, improves the service efficiency of equipment.
Description
Technical field
The invention belongs to image display and its channel setting method, particularly a kind of number for being provided with multiple tuners
Word TV and its channel setting method.
Background technology
With the development of digital television techniques, the stage from analog signal to data signal transition is currently in, a lot
DTV carries digital tuner (Tuner) and analog tuner (Tuner), in the picture for even realizing multi-path digital TV
Draw function and there are multiple digital tuners (Tuner).But still continue each tuner in channel search independently to search for entirely
The method of frequency range, channel search efficiency is not high.
The content of the invention
In order to solve the above technical problems, The present invention provides a kind of method of searching television network information channel, including
Following steps：
S1, TV set power allow to connect and divided in the range of specified channel；
S2, the order by user's input searching television network information channel；
S3, multiple tuner par-allel channels are started according to the order simultaneously searched for；
S4, when multiple tuners carry out par-allel channel search, any one in the multiple tuner skip by
The channel of pinning, and continue to carry out channel search to remaining channel；
S5, in searched channel frequence, detect it is at least one which includes the channel of TV network information with
And broadcast singal channel；
S6, the broadcast singal channel detected stored in memory；In a manner of OSD is shown, produce at least
The channel number of the one TV network information detected；
It is S7, searched if all of channel, then terminate automatic channel search.
Further, the S4 steps are the signal sources for including being represented according to the multiple tuner to each physical channel
The sub-step of scanning mark is set, and the scanning mark is used to identify whether the signal source will search the physical channel
Whether rope and the physical channel have been lockable.
Further, the S4 steps, which also include the physical channel according to the scanning marker for judgment of the physical channel, is
The no sub-step being lockable；As being lockable, then the signal source skips present physical channel；As not being lockable, then enter one
Step judges whether signal source corresponding to the tuner tackles the physical channel search, in this way, then searches for present physical channel,
If not, skip the search that present physical channel continues next channel.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) present invention utilizes parallel search, accelerates search procedure, improves the service efficiency of equipment.
(2) present invention uses multi-tuner, on the screen of the broadcast singal of display channel, adds in the multiple channels of display
The channel for including TV network information.That is, make it possible to include TV network information in search using many places tuner
Channel during, watch the broadcast program being currently viewed.
Below in conjunction with the drawings and specific embodiments, the present invention will be described in detail, but not as a limitation of the invention.
Brief description of the drawings
The accompanying drawing of the present invention is used for providing further understanding of the present application, forms the part of the application, attached at these
Same or analogous part is represented in figure using identical reference number, in the accompanying drawings：
Fig. 1 is the schematic flow sheet of the present invention.
Embodiment
To make the purpose, technical scheme and advantage of the application clearer, below in conjunction with drawings and the specific embodiments, to this
Application is described in further detail, and the schematic description and description of the application is used to explain the application, composition pair
The improper restriction of the application.
As shown in figure 1, a kind of method of searching television network information channel, comprises the following steps：
S1, TV set power allow to connect and divided in the range of specified channel.
S2, the order by user's input searching television network information channel.
S3, start multiple tuner par-allel channels search simultaneously according to order.
S4, when multiple tuners carry out par-allel channel search, any one in multiple tuners, which is skipped, to be lockable
Channel, and continue to remaining channel carry out channel search.
S5, in searched channel frequence, detect it is at least one which includes the channel of TV network information with
And broadcast singal channel.
S6, the broadcast singal channel detected stored in memory；In a manner of OSD is shown, produce at least
The channel number of the one TV network information detected.
It is S7, searched if all of channel, then terminate automatic channel search.
Wherein, S4 steps are to include setting scanning mark to each physical channel according to the signal source that multiple tuners represent
Sub-step, scanning mark is used for whether id signal source will to scan for and whether physical channel is locked to physical channel
Firmly.
Wherein, S4 steps also include the sub-step whether being lockable according to the scanning marker for judgment physical channel of physical channel
Suddenly；As being lockable, then signal source skips present physical channel；As not being lockable, then determine whether to believe corresponding to tuner
Whether number source tackles physical channel search, in this way, then searches for present physical channel, if not, skipping the continuation of present physical channel
The search of next channel.
The present embodiment describes more specific and detailed, also gives some advantageous measures of embodiment, still, the implementation
Example and advantageous measure can not be used as limitation of the present invention, when those skilled in the art sees the program, make other
Deformation and the replacement of equivalent arrangements, all should be within protection scope of the present invention.
