The system includes a processor configured to receive a transport stream including control information associated with the image data including video metadata parameters associated with application specific functions applicable to the image data. The processor is also configured to receive the PES including the frames of image data in video access units. The processor is configured to retrieve and decode the retrieved video access units using the control information to form a signal including the frames of image data. The system also includes a storage device configured to store the frames of image data and the control information.

Information stream management

Aspects of the disclosure relate to management of information streams. The information streams can be delivered according to adaptive streaming mechanisms. In one aspect, a method of data stream management can comprise receiving a plurality of data streams having a specific bit rate and a segmentation signaling structure, comprising at least one segmentation signaling marker. The method may also comprise monitoring the segmentation signaling structure of at least one data stream and supplying, based on the monitoring, a metric indicative of compliance with a predetermined segmentation signaling structure.

Personal Video Recorder

A sequence of picture slices is encoded as reference slices and non-reference slices, wherein the reference slices include B slices, by forming, for each B slice, at least one data packet containing data values derived from brightness and color information pertaining to the slice. The data packet for each B slice includes a header element indicating whether the B slice is a reference slice. The header element of each reference B slice has a value that depends on depth of the reference B slice in a hierarchy of discardability.
