Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
Embodiment 1
As shown in Figure 1, a kind of method that improves television video output equipment interactive channel selection speed may further comprise the steps:
(1) in the present embodiment, at first the station symbol with TV station is stored in the server of the Internet in advance, and TV station's station symbol of storage has the station symbol of the Chinese Central Television (CCTV), BTV, Hebei TV station, Sichuan TV station etc.;
(2) adopt TV in the television video output equipment present embodiment, when TV when playing TV programme, TV station's station symbol identification module is analyzed the video flowing of televising, detect and extract TV station's station symbol, then TV station's station symbol of having stored on TV station's station symbol of extracting and the middle server of step (1) is compared, if find it is known TV station's station symbol, can determine the TV station that the user is watching, then the one-to-one relationship of television channel and TV station's title is preserved, then TV station's title directly is presented on the interface of TV, in the present embodiment, the Chinese Central Television (CCTV), BTV, Hebei TV station, TV station's name of Sichuan TV station etc. is called its corresponding station symbol pattern, and directly the mode with tabulation is presented on the interface of TV; Show the TV play listing that each is broadcasting simultaneously, listing can sort by programme variety, is arranged in together as TV station and the TV play title that will broadcast the TV play program, and the user selects program that reference is provided;
In the present embodiment, TV station's station symbol identification module is analyzed video flowing, extracts TV station's station symbol and when the station symbol on the server contrasted, the concrete grammar of employing was:
1) extraction of station symbol: the video flowing of televising is analyzed, and in the present embodiment, directly the video flowing analysis at TV display station cursor position gets final product.Be under 720 * 576 the pal mode in resolution, station symbol is generally shown in the wicket zone of video screen upper left corner 200mm * 150mm, therefore directly detect in the video flowing in this window ranges and whether have station symbol, if station symbol exists then directly extracts station symbol, this is because in most cases, station symbol is constant, comprises its shape, position etc.; Even have the station symbol of animation effect, also just occur in the animation of regional area or very short time, in general with respect to the rich video content, station symbol is metastable.Just because of the good stability of station symbol, therefore, when extracting station symbol, only need detect in the video flowing in the wicket zone of video screen upper left corner 200mm * 150mm and whether exist station symbol to get final product, concrete grammar is as follows:
In the statistics certain hour section in (get final product in general 1 minute) window area brightness change the number of pixels that is less than or equal to threshold value, if the brightness variation is less than or equal to threshold value, then think this pixel no change; If being greater than or equal to threshold value, constant pixel quantity just can judge and have station symbol in the window that these constant pixels have just been formed the station symbol zone.The mean value of each pixel promptly obtains the average image of this section period in the calculation window zone, suppresses non-station symbol zone wherein, has just obtained the image of station symbol;
2) identification of station symbol: after extracting station symbol, compare, calculate both similarities with extracting the station symbol template of storing on result and the server.In the present embodiment, the calculation of similarity degree method adopts following formula to define:
Wherein, γ represents similarity, and Mask represents the station symbol zone of extracting, f (x, the y) value of the pixel of abscissa x and ordinate y in the station symbol image of representing to extract, w (x, y) value of the pixel of abscissa x and ordinate y in the station symbol image that stores on the expression server, and
Represent respectively f (x, y), w (x, mean value y).Similarity is big more to show that the possibility that has this station symbol in this video is big more.Find station symbol, and this maximum similarity determines that the station symbol of this section video is the final TV station that determines in identification back when being greater than or equal to threshold value with maximum similarity.
(3) as user during at the television channel of selecting to watch, the corresponding program that is just broadcasting of the TV station's title that shows on the interface according to TV with Ge Tai, according to the hobby of oneself, the corresponding TV station title of directly selecting oneself to like on the interface of TV by remote controller gets final product.
Embodiment 2
As shown in Figure 2, a kind of device that improves television video output equipment interactive channel selection speed, this device comprises: television video output equipment, TV station's station symbol identification module, server;
Said apparatus is when work, its workflow is as follows: when the television video output equipment computer or the TV of tv receiver card/box (as have) is play TV programme, TV station's station symbol identification module identifies the feature of TV station's station symbol, and with the server of the Internet or local area network in TV station's station symbol feature of storing contrast, when finding to be known TV station station symbol, just can determine which TV station current channel has been; All preserve concerning one to one between all television channels and the TV station's title then, then TV station's title directly is presented on the interface of television video output equipment; When channel that the user selects oneself to like, directly select the title of TV station just passable (, select more convenient with mouse for the computer that has tv receiver card/box; For TV, remote controller commonly used is selected), the television video output equipment can be directly switch on the corresponding television channel according to the corresponding relation of television channel and TV station's title, so just improved the speed of user's channel selection greatly, do not need the user to remember television channel number yet, very convenient during application.
Method of the present invention is not limited to the embodiment described in the embodiment, and those skilled in the art's technical scheme according to the present invention draws other execution mode, belongs to technological innovation scope of the present invention equally.
