Claim 12:
13. A transmission method of streaming data conforming to the Common Media Application Format (CMAF) for reducing a processing delay of a proxy server in a network environment via the proxy server and for outputting chunk data obtained by dividing a segment, which is a transmission unit of picture data, into chunks, which are transmission units smaller than the segment, as streaming data, the transmission method comprising:
calculating a chunk length which is a time length of the chunk;
generating the chunk data by dividing segment data, which is data of the segment, into chunks in accordance with the chunk length;
determining the chunk length based on a data size of picture data to be included in the chunk; and
when recognizing that a received picture is an I picture, setting the chunk length to be shorter than a chunk length set as a fixed length.
