The complicated selection step by step, in addition to the inexperience of the user in using the set-top box, once the user selects the wrong link in the middle, wrong data is configured, all the display information of the software in the back is further wrong, and the user has to reselect to use the software, so that the use and the popularization of the live broadcast software are not facilitated. In the prior art, television signals and programs can be managed mainly by station caption identification and use, but the method mainly focuses on identification precision and station caption library construction, and less station caption identification related equipment is used for facilitating use and operation, so that an automatic identification and matching method between a set top box remote controller, a channel table and an intelligent television serving as a base is very important.
For example, chinese patent (publication No. CN 102426647B) discloses "a method and an apparatus for station logo identification", the method includes: collecting a video frame image output by a set top box; calculating a change image between adjacent frames of the video frame image, extracting the edge of the change image, and simultaneously performing adaptive threshold processing on the edge of the change image to obtain a station logo region binary image; extracting the characteristics of the station caption area binary image, matching the characteristics of the station caption area binary image with the characteristics of a station caption template in a pre-generated station caption template library, and obtaining candidate station captions according to the matching result; and counting a candidate station logo set obtained in a preset time period, and obtaining a station logo identification result according to the candidate station logo set and a preset judgment criterion. The invention enables the detection of the station caption area to be more accurate, and is particularly suitable for identifying the semitransparent station caption.
For another example, chinese patent (No. CN 103729657 a) discloses "a method and an apparatus for constructing a station caption sample library and station caption identification", the method for constructing a station caption sample library includes: acquiring a station caption area in a television picture, and intercepting the station caption area to obtain a station caption area map; extracting a station caption part from the station caption area image to obtain a station caption identification image with the station caption part being white and the non-station caption part being black; performing AND operation on the station caption identification image and the station caption area image to acquire a station caption image containing station caption content; and storing the station caption identification graph and the station caption image into a station caption sample library together as a station caption sample. By constructing the station caption sample library and storing the station caption samples with consistent specifications required during station caption identification, the station caption identification drawing and the station caption image required during station caption identification are provided, and the efficiency of station caption identification is improved.
The method is still an improvement on station caption identification precision and a station caption sample library construction method, and does not relate to the problems of how to realize automatic identification and matching of a remote controller and a channel table through the station caption and the like.
