Abstract:
A digital video conversion device is communicatively coupled to a TV set and a TV signal source, respectively, to pass TV signals from the TV signal source to the TV set. Upon receipt of a TV channel identification request from a mobile terminal via a wireless communication channel, the digital video conversion device acquires an image from the TV signals currently broadcasted on the TV set and extracts a plurality of station logo characteristic sets from the image, each station logo characteristic set corresponding to one of a plurality of station logo templates. After calculating a similarity score between each station logo characteristic set and a corresponding station logo template, the digital video conversion device identifies one of the plurality of station logo templates as matching the image based on their similarity scores and returns TV channel information associated with the identified station logo template to the mobile terminal.

Claim (Index 15):
A non-transitory computer readable storage medium in conjunction with a digital video conversion device storing one or more program modules, wherein the digital video conversion device is communicatively coupled to a TV set and a TV signal source, respectively, so as to pass TV signals from the TV signal source to the TV set, wherein the one or more program modules further include instructions, which, when executed by one or more processors of the digital video conversion device, cause the processors to perform operations including:\n receiving a TV channel identification request from a mobile terminal via a wireless communication channel; in response to the TV channel identification request:\n acquiring an image from the TV signals currently broadcasted on the TV set;\n extracting a plurality of station logo characteristic sets from the image, wherein each station logo characteristic set corresponds to one of a plurality of station logo templates and each station logo template includes a station logo type and one or more station logo image attributes corresponding to the station logo template, further including:\n for each of the plurality of station logo characteristic sets, extracting a set of station logo image attributes from the image according to the station logo type of a corresponding station logo template; \n \n calculating a similarity score between the set of station logo image attributes of each station logo characteristic set and the one or more station logo image attributes of a corresponding station logo template according to the corresponding station logo type; \n identifying one of the plurality of station logo templates as matching the image based on their similarity scores; and \n returning TV channel information associated with the identified station logo template to the mobile terminal.
