<p><P>PROBLEM TO BE SOLVED: To optimize the storage to packets of NAL units by dividing and concentrating the NAL units, thereby improving the efficiency of video data transfer and improving the efficiency of error correction processing. <P>SOLUTION: In the video data transmitter, the NAL units outputted by an encoder 1 are stored in a buffer 21 and tentatively stored. A NAL unit combination determination means 22 calculates the length Lf of the margin portion of the packet generated when the first NAL unit longer than the maximum length that can be stored in the packet is divided and stored in the plurality of packets on the basis of the length of the NAL unit stored in the buffer 21 and the maximum length that can be stored in the packet, extracts a second NAL unit whose total length is within Lf from the group of other short NAL units, and determines the combination of the NAL units. A packet generation means 23 divides and stores the combined NAL units in the plurality of packets and generates the packets. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
