摘要： Techniques to efficiently deliver interactive program guide (IPG). In one aspect, if an IPG page is requested by a viewer and not already transmitted, only the guide portion for the requested page is sent instead of the entire page. The requested page includes a guide portion that is specific to the requested page and a background portion that is common for a number of pages. The background portion can be continually broadcasted by the head-end. The requesting terminal is thus able to regenerate the requested page based on the demand-casted guide portion (i.e., transmitted upon request) and the continually broadcasted background portion. Alternatively, the entire requested page can be transmitted. In another aspect, instead of sending the requested guide portion continually, the guide portion is sent a limited number of times (e.g., only once, upon receiving the request). Since the guide portion for any particular page is normally static and does not change over time, sending the guide portion a limited number of times (e.g., once) is typically sufficient and greatly reduces bandwidth usage.

摘要： Indexing techniques to maintain track of IPG pages and allow a terminal to determine whether a selected IPG is currently received and available, which regions are to be assembled together to generate the selected page, and which packet identifiers (PIDs) are to be processed to recover the needed regions. In one method, a “roster” is formed which includes a number of record elements, with each record element being associated with and identifying a respective IPG page received at a terminal. Each record includes a page ID field that specifically identifies the associated IPG page. A number of fields may be included in each record element such as fields for a guide PID, a video PID, a data PID, and so on. The roster is updated to reflect changes in IPG pages received at the terminal.

摘要： A data structure for representing program data that includes a number of streams. Each stream comprises a group of pictures (GOP) having a first picture and remaining pictures. The data structure includes a first set of one or more elements for representing data for the first pictures in the GOPs, and a second set of one or more elements for representing data for the remaining pictures in the GOPs. At least one element in the first set represents data for the first picture of at least one respective GOP, with each such first picture having been encoded as a reference I picture. Each remaining element (if any) in the first set represents data for the first picture of a respective remaining GOP, with each such remaining first picture having been encoded as either a difference picture or a P picture. Each element in the second set represents data for a particular remaining picture in one of the GOPs, with each such remaining picture having been encoded as either a P or B picture. Each stream is represented by one or more elements in the first set and one or more elements in the second set.

摘要： An interactive program guide (IPG) may include a program grid section and a multimedia section. The program grid section typically contains program information organized in a grid with a time axis and a channel axis. The multimedia section may include video for advertisement, previews, and other purposes. Such an IPG may be rendered and encoded at a server and distributed to client terminals in the form of compressed bit streams.For certain IPGs, the program grid section may comprise alternating stripes of background with different shades (lighter/darker) or different colors. Typically, the alternating background stripes may be used to visually separate text information into timeslots or channels.Blank areas of the background may be “skip” encoded to “save” a portion of the bit rate. Meanwhile, the quantizer stepsize for encoding that section may be lowered so as to utilize the saved bits to improve the viewing quality of the program grid section. Additionally or alternatively, the quantization matrix for encoding the program grid section may be optimized for encoding text (rather than being, for example, a standard quantization matrix).Encoding may be performed on the program grid section such that encoded macroblocks do not cross a border between two stripes. In other words, each encoded macroblock in the program grid section may be within a single stripe. Additionally or alternatively, low-pass frequency filtering may be applied on the background stripes. Such low-pass filtering reduces visual defects due to ringing from edges between stripes.

摘要： A method and apparatus for combining video frame sequences with a video display of an interactive program guide (IPG). The apparatus comprises a plurality of compositors that combine background information, video frame sequences and program guide graphics into a single video frame sequence. The sequence is then digitally encoded to form an MPEG-like bitstream. The same background information and informational video is composited with a different program guide graphic to form another video sequence that is also encoded. A plurality of such sequences are produced with each sequence having a different program guide graphic. Each sequence is encoded and then multiplexed into a transport stream such that all the encoded sequences are transmitted to a subscriber's terminal using a single transport stream. As such, the subscriber can transition from one program guide to the next without interruption of the background or video display as the program guide graphic is changed.

摘要： Techniques to efficiently deliver interactive program guide (IPG) to a number of terminals. Each IPG page can be decomposed into a guide portion that is specific to each IPG page and a background portion that is common for all IPG pages. The background portion can be further decomposed into a time-varying video portion and other static portions. One method includes receiving a viewer selection for imagery, where the imagery includes at least one intracoded slice and at least one predictively coded slice, and each of the intracoded and predictively codes slices are associated with respective bitstreams. Packets from the at least one bitstream corresponding to the at least one intracoded slice of the selected imagery are extracted, and packets from the at least one bitstream corresponding to the at least one predictively coded slice of the selected imagery are also extracted. The payload portions of the extracted packets are then arranged to form the selected imagery.

摘要： A terminal for decoding and presenting encoded realtime and non-realtime interactive program guide (IPG) content including a realtime video portion and a non-realtime guide graphics portion. The terminal includes a demodulator operative to receive and demodulate a modulated signal to provide a transport stream, and a transport demultiplexer coupled to the demodulator and operative to receive and process the transport stream to provide a sequence of transport packets re-timestamped to synchronize encoded realtime content and encoded non-realtime content included therein. At least one video decoder is coupled to the transport demultiplexer and operative to receive and decode the encoded realtime and non-realtime contents to recover the realtime and non-realtime contents for the user interface.
