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.

Abstract: A method of presenting interactive content at a client device is disclosed. The client device records, in real-time, an audio stream of a piece of multimedia content broadcast by a content display device and sends an audio fingerprint of the piece of the multimedia content to a server. The server then determines, based on the audio fingerprint, an identifier of the piece of multimedia content, retrieves, based on the identifier of the piece of multimedia content, interactive content associated with the piece of multimedia content, and returns the interactive content associated with the piece of multimedia content to the client device. After receiving, from the server, the interactive content associated with the piece of multimedia content, the client device renders the interactive content to the user of the client device.

Abstract: A method and an apparatus for image identification are provided. For example, the processing circuitry of the apparatus obtains first feature values of a first image feature for pixels in an image for barcode detection. The processing circuitry calculates measures that are indicative of changes of the first feature values in multiple directions within the image and determines a target area in the image for the barcode detection according to the measures. Further, the processing circuitry divides the target area into a plurality of sub-areas, and filters the sub-areas to determine a target sub-area for the barcode detection. Then, the processing circuitry obtains second feature values of a second image feature for the target sub-area. The second image feature is derived from the first image feature. The processing circuitry then identifies a barcode type in the target sub-area according to the second image feature.
