Abstract:
1. A streaming server for streaming data coded by inter-frame prediction, the streaming server comprising: a buffering-key-frame generator for generating transmission data including an independently decodable key frame and at least one difference frame following the key frame, and for generating a buffering key frame added with information on the transmission data, the information including a frame number; and a frame transmitter for transmitting, with first transmission timing, a first buffering key frame generated with a key frame previously transmitted in stream data and at least one difference frame also previously transmitted in the stream data and following the key frame, such that the key frame and the at least one difference frame are retransmitted within the stream data in the first buffering key frame, and for transmitting, during the interval between the first transmission timing and a second transmission timing, at least one difference frame following the difference frame used in generating the first buffering key frame, and wherein the first transmission timing and the second transmission timing are continuous timings among predetermined periodical timings.
