Abstract
Methods and apparatus are provided for converting video packets into IP packets. Video packets including null packets associated with timing information are received at a network entity coupling a video network to an IP network. Video packets are selectively combined into IP packets to allow transmission of video data onto the IP network in an efficient and effective manner. Null packets used to maintain timing information in the video network are removed. Mechanisms are provided for maintaining timing information even without transmitting extraneous packets.
