摘要： A method and apparatus for compressing and transmitting both video and graphics portions of an interactive program guide (IPG). For an IPG that comprises a graphics portion and at least one video portion, the inventive system separately encodes the video portion and the graphics portion. The video portion is slice-base encoded using a predictive encoder (408), e.g., an MPEG encoder, that produces a bitstream comprising intra-coded picture slices and predictive-coded picture slices. The graphics portion is separately slice-base encoded using a guide encoder (416) to produce encoded slices of the graphics image. The encoded slices of the graphics portion can be stored in a database (418) and recalled as needed for transmission. To transmit an IPG, a transport stream is created containing the intra-coded and predicted picture streams as well as the encoded slices that comprise a graphics image that is to be included in the IPG. The receiver reassembles the components of the IPG into a comprehensive IPG.

摘要： A head-end centric system and apparatus for encoding and delivery of realtime and non-realtime content including: a non-realtime content source for providing guide content; a guide encoder (416) for encoding the non-realtime content into encoded non-realtime content; a realtime content source for providing realtime video and audio content; a realtime encoder unit (408) for encoding the realtime video and audio content into encoded realtime video and audio; a remultiplexor for repacketizing the encoded non-realtime content and the encoded realtime video and audio into transport packets; and a re-timestamp unit coupled to the remultiplexer for providing timestamps to be applied to the transport packets in order to synchronize the realtime and non-realtime content therein.
