Phase Estimation in Video Transmission using Hilbert Transform

Channelization is one of the important techniques for sharing a single physical channel among the multiple videos. In channelization the videos are partitioned into segments and the bandwidth of the physical channel is partitioned into logical channels. The first segment of each video is transmitted through the first logical channel, the second segment of each video through the second logical channel, and so forth. The segments are transmitted periodically through the logical channels. In this paper, the video signals to be transmitted through different logical channels are estimated. Furthermore, using the Hilbert transform the phase is estimated by incorporating the jitter delays occurring among the video segments while transmitting through the logical channels. The phase is helpful in estimating the storage space at the user's site so that continuous delivery of the video services can be maintained
