The core technology to resolve all these problems is the bit - rate control of the motion video data - stream used in mpeg - 2 standard 要解决如上问题,核心技术是进行mpeg - 2的运动视频数据流的码率变换。
The vod system is a network system including hardware and software . the vod software transmits multi - path , concurrent video data - stream real time from video server to client 视频点播系统是一个包含硬件和软件的网络化系统,主要特征是实时和按需求从视频服务器向客户设备传送多路、并发的视频数据流。
Based on the correlation structure of real - time variable bit rate video traffic , this paper proposed a dynamic bandwidth allocation ( dba ) algorithm with adaptive linear traffic prediction in ethernet passive optical network ( epon ) 摘要根据视频数据流的长程相关性特点,提出一种以太无源光网络中面向实时可变比特率视频的动态带宽分配算法。
For resource limited , the motion - video data stream with high bit - rate value used in mpeg - 2 standard can not forward exactly by media . or for the sake of resource more efficiently utilized , more multi - pass program streams can be forwarded in certain bandwidth Mpeg - 2的视频数据流在带宽资源不够条件下,常常无法正常地传输,或者在一定的带宽资源条件下,如何传输更多的节目流,更有效地利用带宽资源?
However , video communication can tolerate some kind of data error or loss and different parts of video bitstream have unequal error sensitivities . so we need new error control methods designed especially for video communicaton 同时视频数据能够容忍一定的误码和丢失,并不需要绝对的无差错传输,而且视频数据流的不同部分对错误的敏感度也不同,因此有必要也有可能根据视频通信的特点研究新的差错控制方法。
