摘要
En 中文
Interframe coding techniques, such as those used in MPEG video, give rise to a sequence of encoded pictures whose sizes (in number of bits) differ by a factor of ten or more, Buffering is needed to reduce fluctuations in the rate at which video packets are sent to a network connection, In this paper, we design and specify a lossless smoothing algorithm, characterized by three parameters: D (delay bound), K (number of pictures with known sizes), and H (lookahead interval), We prove a theorem which guarantees that, if K greater than or equal to 1, the algorithm finds a solution that satisfies the delay bound, We present the algorithm's performance from a large number of experiments conducted using MPEG video traces, Lastly, we discuss algorithm implementation.
