Abstract:
1. A data reproduction apparatus for receiving any of plural video data having different anti-error properties, and reproducing the received data, the data reproduction apparatus comprising: an auxiliary data reception unit for receiving auxiliary data indicating anti-error intensities of the respective video data; a data designation unit for generating a data designation signal which designates one of the plural video data, on the basis of a condition relating to video data to be received, and the anti-error intensities of the respective video data, which are indicated by the auxiliary data; a data transmission unit for transmitting the data designation signal; and a video data reception unit for receiving the video data which is selected from among the plural video data on the basis of the transmitted data designation signal, and then transmitted; wherein each of the plural video data having different anti-error properties includes intra-frame coded data which is obtained by coding a digital video signal employing intra-frame pixel value correlation, and inter-frame coded data which is obtained by coding the digital video signal using inter-frame pixel value correlation; and wherein appearance intervals of intra-frame coded data in the respective video data are different from each other.
