Abstract
A method of operating a server and an IP client device for presentation of video content to a viewer that includes a trickplay function. The server partitions media chunks into several sub chunks and includes information about the sub chunks in a manifest. The client plays the needed sub chunks to implement a desired play rate. As an alternative to providing sub chunk information in the manifest, the server sends key frame information in the manifest. The client plays needed frames of the key frames to implement a desired play rate. The sub chunk information as well as key frame information is encoded into the manifest as a standard comment or chunk filename. In another alternative, the IP client sends a trickplay request and based on that, the server signals either the sub chunks to be played or the key frames to be played to affect the desired speed. In yet another variation, the server can also remove the unwanted sub chunks or key frames to affect the desired play rate at the IP client.
