PROBLEM TO BE SOLVED: To secure a processing capacity for decoding coded contents data. SOLUTION: A data reception device 23 for receiving contents data transmitted from a data transmission device 21 for decoding processing confums the details of meta data where information regarding the coding of the contents data is described. When a plurality of data processings are requested by a decoding processing part 43, the decoding processing part 43 selects top priority processing from each processing order being set to the meta data, and performs processing from the top priority processing. The decoding processing part 43 calculates time required for other processing, and judges whether other processing can be made or not until the data unit of the contents data requiring the next top priority processing is transmitted from a data processing judgment part 42. The decoding processing part 43 performs processing when it judges that other processing can be made, and confirms the handling information of other processing being set to the meta data when other processing cannot be made, and performs processing based on the handling information.
