Television channel searching method and device

Abstract

The invention provides a research method for a TV channel and a device thereof. The method comprises the steps that: step 11. a screenshot screen is generated after the screenshot process to the real-time video signal of a frequency point; step 12. corresponding relationship between the screenshot screens and the frequency points is established and stored; step 13. the screenshot screens are provided to users for choose, and the screenshot screens chosen by the users are acquired; step 14. switching and broadcasting of a target TV channel are realized after the corresponding frequency points of the screenshot screens chosen by the users are acquired according to the corresponding relationship between the screenshot screens and the frequency points. The method and the device of the invention can realize the search of channels fast and intuitively according to the corresponding relationship between the screenshot screens and the frequency points, are independent on EPG information and can be applied to a simulating TV and a digital TV.

Description

technical field

[0001] The present invention relates to a TV search technology, in particular to a method and device for realizing TV channel search, which can be applied to analog TV and digital TV, and does not depend on EPG (Electrical Program Guide, Electronic Program Guide) information. Background technique

[0002] With the gradual maturity of the digital home concept and application scheme, applications such as TV broadcasting and TV program recording have become one of the important contents of the digital home application scheme.

[0003] But the current TV programs, whether they are analog or digital, have quite a lot of channels. For example, in China, in addition to satellite TV, there are about 80 channels on analog TV in many places, including some local TV stations. As for areas where the digital TV business is relatively mature, the number of digital TV programs can reach 500 or more.

[0004] For so many channels and programs, users need a very effective ch...

[0061] In the first embodiment, the present invention is only described for ordinary channel lookup.

[0062] The first embodiment of the present invention is as image 3 shown, including:

[0063] Step A1, at each frequency point where there is a TV channel, perform screen capture processing on the real-time video signal of the TV channel at the frequency point to generate a screen capture picture; this step is preferably processed when searching for channels, namely:

[0064] While searching for channels, at each searched frequency point where there is a TV channel, the real-time video signal of the TV channel at the frequency point is screened and processed to generate a screen shot.

[0065] Step A2, establishing and saving the corresponding relationship between the screenshot and the frequency point;

[0066] Step A3, providing a screen shot for the user to select, and obtaining the screen shot selected by the user; here, judging the screen shot selected by the user accor...

[0069] Considering that the user is watching TV programs, when several channels are broadcasting programs that the user likes very much (such as football game programs, the number of games that may be broadcast by each channel is different), the user will switch between multiple TV channels very frequently , therefore, in the second embodiment, the present invention is described for channel review.

[0070] In the second embodiment, the method of the present invention is as Figure 4 shown, including:

[0071] Step B1, perform screenshot processing on the real-time video signal of the first frequency point corresponding to the predetermined number (here, the predetermined number should be greater than or equal to 3) of TV channels that the user has watched recently, and generate a screenshot;

[0072] Step B2, saving and updating the corresponding relationship between the screenshot and the frequency points;

[0073] Step B3, providing the screen shot corresponding to the fr...

[0077] Considering that the user has some frequently used TV channels, therefore, in the third embodiment, the present invention will be described for frequently used TV channels.

[0078] In the third embodiment, the method of the present invention is as Figure 5 shown, including:

[0079] Step C1, performing screenshot processing on the real-time video signal of the frequency point corresponding to the commonly used TV channel selected by the user to generate a screenshot;

[0080] Step C2, saving and updating the corresponding relationship between the screenshot and the frequency point;

[0081] Step C3, providing the screen shot corresponding to the frequency point for the user to select, and obtaining the screen shot selected by the user;

[0082] Step C4, according to the corresponding relationship between the screenshot and the frequency point, switch to the frequency point corresponding to the focused screenshot to realize switching and playing of the target TV chan...
