Description

Utilize the channel control apparatus and the method for the DTV receiver of television set

Technical field

The present invention relates to a kind of DTV receiver, especially utilize the channel control apparatus and the method for the DTV receiver of television set.

Background technology

Recently, the number broadcasting receiver of digital TV (TV) signal of HD level occurred receiving in market, wherein, Digital Television (DTV) receiver (STB, Set Top Box) is not because there is display unit, and production cost is lower, because of the cheap favorable comment that is subjected to market.

This digital broadcast (Digital Broadcasting) not only provides thousands of channels up to a hundred, as data, services, the relevant information of listing or each programme content also is provided, electronic programming introduction (electronicprogram guide:EPG) is in its basic service, and, the digital TV that is not only high image quality that broadcasts broadcasts, also to the user provides channel program timetable information, the existing analog broadcastings such as Additional Services that provide about the information of charge program and service, each program can't be unrealistically compared many data.Because the DTV receiver does not possess display unit, can not receive the analog TV broadcast singal, generally connect under the situation of DTV receiver in analog TV, can receive analog broadcasting and digital broadcasting.

Channel control method about the analog TV of traditional connection DTV receiver is described as follows:

In user's audiovisual analog broadcast channel way, when thinking audiovisual DTV broadcasting channel, utilize TV remote, switch the input of TV key frame to the input pattern that connects the DTV receiver; And, utilize the remote control of DTV receiver, the input of receiver is changed to DTV after, rechange desirable DTV channel into the user.

At this moment, the input of the key frame of analog TV is switched the source to the DTV channel.

But, in above-mentioned traditional channel control method, the remote controller of analog TV and DTV receiver need be provided to the user, and when thinking audiovisual DTV broadcasting channel, exist following loaded down with trivial details: after utilizing TV remote to switch the input pattern of TV input pattern for the DTV receiver, utilize the remote control of DTV receiver again, the input of receiver is switched to the DTV channel, the remote controller that promptly needs TV and DTV receiver respectively, when the user wants by TV audio/video DTV broadcasting channel, need input repeatedly to switch, have the problem that causes user's inconvenience.

Summary of the invention

The object of the present invention is to provide a kind of channel control apparatus and method of utilizing the DTV receiver of television set, can integrate the channel map (Channel Map) that constitutes analog TV and the DTV receiver that is connected therewith, control the channel of DTV receiver by analog TV simultaneously.

For achieving the above object, the technical solution used in the present invention is:

It has following two parts and constitutes: possess in order to search for the receiver tuner of digital broadcasting channel, and possess according to the channel search order, search for whole digital broadcasting channels by above-mentioned receiver tuner, when above-mentioned digital broadcasting channel search finishes, transmit the DTV receiver of the receiver control part of digital broadcasting channel information; Possess in order to search for the TV tuner of simulating broadcasting channel and to possess the control TV, the channel search order of identification user input, all simulate broadcasting channel by above-mentioned TV tuner search, when above-mentioned simulation broadcasting channel search finishes, after above-mentioned DTV receiver transmits the channel search order, obtain the input of the digital broadcasting channel that transmits from above-mentioned DTV receiver, constitute the TV of the control part of channel map (Channel Map) with the simulation broadcasting channel integration of above-mentioned search.

And in order to achieve the above object, the channel control method that utilizes TV DTV receiver of the present invention is to form feature as the next stage: the user is during by TV input automatic channel setting, the stage of searching for all analog broadcast channels; When the search of above-mentioned analog broadcast channel is finished, transmit the stage of channel search order to DTV receiver; Judge whether to receive the stage of the digital broadcasting channel information of searching for according to the channel search order from above-mentioned DTV receiver; And above-mentioned judged result when above-mentioned DTV receiver receives digital broadcasting channel information, is integrated the digital broadcasting channel information of above-mentioned reception and the analog broadcast channel of above-mentioned end search, constitutes the stage of channel map (Channel Map).

The present invention has the following advantages:

1. because integrate analog broadcast channel and digital broadcasting channel formation channel map,, has identical effect with built-in (Built-in) DTV by TV centralized management DTV channel;

2. only control the DTV channel simultaneously, do not need more remote controller and input for several times to switch, not only can improve the convenience in the use greatly, can also improve system effectiveness greatly by control to TV.
