Abstract:
PROBLEM TO BE SOLVED: To provide a video data recorder that records video data with proper image quality in response to contents or preference without the need for a user to be conscious of complicated setting of coding parameters. SOLUTION: A coding control section 102 sets coding parameters required to code coding object video data, that is, at least one parameter or over among a coding rate in the case of the coding object video data, a retrieval range of a motion vector in the case of detecting the motion vector, a mode of motion compensation and a mode of adaptive quantization on the basis of information relating to contents of video data being a coding object, that is, information relating to a genre of contents of the video data, or at least one set of information or over among sets of structural information of the video data. Thus, a coding section 104 applies proper coding to the video data on the basis of contents of the video data to be recorded.
