摘要
为了有效地满足视频点播和充分利用网络带宽的需要,文中提出了一种实现MPEG-2传输流复用的方法,着重分析了视频音频同步、码率控制、PCR计算、缓冲区管理等关键技术的实现策略,在VC++6.0环境下进行了编程实现,并用分析软件对生成的传输流进行分析,结果表明输出传输流符合MPEG-2系统层标准。
In order to meet the requirement of VOD and using bandwidth of network,a technique of multiplex elementary streams to MPEG- 2 transport stream arithmetic is intruduced.And put forward software implementation about video and audio synchronization,biterate control,calculating PCR and management of buffer in VC++6.0.The results show that the transport stream conforms to the standard of system layer of MPEG-2.
