摘要： A user interface for an interactive information distribution system comprising a graphics region, a video region and a mask/reveal layer. The user interface is generated in a head end of the system as a digital bitstream and transmitted to subscriber equipment for display. Operation of the user interface is facilitated by functions on both a local level with the subscriber equipment and on a system level within the head end. One embodiment of the user interface is an interactive program guide.

摘要： Methods for managing delivery of video sequences of an interactive program guide (IPG) over a communications network to a plurality of terminals are provided. In one embodiment, the method pre-allocates a broadcast bandwidth in the communications network for common video sequences to be transmitted by a broadcast technique. The common video sequences are transmitted in the broadcast bandwidth to the plurality of terminals by way of the broadcast technique. A request for a specific video sequence is received from a specific terminal via the communications network. A demandcast bandwidth is allocated in the communications network for the specific video sequence. The specific video sequence is transmitted in the demandcast bandwidth to the specific terminal via the communications network.

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.
