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： An “all-in-one” encoder that simultaneously produces an MPEG-2 compliant fast forward, fast reverse and play bitstreams from a sequence of video frames, e.g., 601-format video. The encoder subsamples the video sequence, extracting a plurality of frames from the video sequence and buffering the subsampled frames. Simultaneous with the subsampling and buffering, the source frames are encoded within a real-time encoder, e.g., an MPEG-2 encoder. The buffered frames are recalled from the buffer and coupled to a second real-time encoder. The second encoder forms both the fast forward and fast reverse bitstreams using a time multiplexing technique wherein a group of pictures (GOP) for the fast forward stream can be formed, followed by the compression of the same GOP having the frames organized in reverse order. As such, the compressed GOPs are represented by the fast forward and fast reverse bitstreams. The play, fast forward, and fast reverse bitstreams for each GOP are organized into a file and stored on the mass storage device (e.g., disk drive array) of the file server.

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 system and method for efficient delivery of video segments. One embodiment relates to the delivery of short-time duration video segments. The video segments may be delivered as part of a media-rich interactive program guide (IPG) or for some other application. The system and method provides a viewer with access to a video segment starting at its beginning (or any other selectable point within the video segment). Such access may be provided using a server-centric interactive technique. The server-centric technique may involve use of a demand-cast system and method. Demand-cast messaging may occur between a session manager, transport stream generator, and terminal. For example, a video object on a screen may be activated by a viewer using a remote control for a terminal. Activation of the object may cause transmission of a request from the terminal to a session manager for a video segment corresponding to the object. In response to the request, the session manager may initiate a process to accomplish delivery of the video segment from a transport stream generator to the terminal.
摘要翻译：一种用于高效传送视频片段的系统和方法。一个实施例涉及短时间段视频片段的传送。视频段可以作为媒体丰富的交互式节目指南（IPG）或其他一些应用的一部分来传送。该系统和方法为观众提供从其开始（或视频片段中的任何其他可选点）开始的视频片段的访问。可以使用以服务器为中心的交互技术来提供这种访问。以服务器为中心的技术可能涉及使用需求转换系统和方法。会话管理器，传输流发生器和终端之间可能发生请求转移消息。例如，屏幕上的视频对象可以由观看者使用终端的遥控器激活。对象的激活可能导致从终端向与对象相对应的视频片段的会话管理器发送请求。响应于该请求，会话管理器可以启动完成从传输流发生器到终端的视频段的传递的过程。
