摘要： In one embodiment, a video stream is received, and a spatially distinct region of a frame in the received video stream to be modified is identified, the spatially distinct region of the frame being encoded separately from any other region in the frame. A segment of the spatially distinct region of the frame to be modified is extracted. The extracted segment of the spatially distinct region is modified. The extracted segment of the spatially distinct region into a single-segment spatially distinct region is encoded. A network abstraction layer (NAL) header is associated with the encoded single-segment spatially distinct region. The encoded single- segment spatially distinct region and its associated NAL header is inserted into the received video stream following the identified spatially distinct region of the frame to be modified. Related methods, systems and apparatus are also described.

摘要： A method of content recording and playback is carried out in a receiving device by selecting one of a plurality of digital content streams (80, 82, 84), which have respective distribution arrangements. A content segment (90) of a review buffer (88) is established and configured for the one content stream. While recording the one content stream in the review buffer (90), a content source change operation is performed to record another content stream in the review buffer (88) by discontinuing recording of the one content stream, and iterating establishing, configuring and recording with a new content segment (92). Recorded content of the content segment (90) and new content segment (92) are stored in respective data stores (102, 100). The content streams may be replayed in an order or a reverse order of recording thereof by retrieving data from respective content segments or data stores. Related apparatus is also described.
