Abstract: 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.

Abstract: A set top terminal equipped with a camera and microphone includes the capability to send and receive video calls through a cable television delivery system or other communications networks. In response to detection of the occurrence of a video call event or triggering event, a video program is automatically paused. In response to an incoming video phone call, message, web page, or other video communications information, the system pauses the video program and displays an indication of the occurrence of the communications event. The system also buffers the video program while paused, permitting a user to replay missed portions of it. Alternatively, the system waits for a triggering event, which includes the user's access to the communications event, in order to pause the video program. The set top terminal also includes features for caller identification of video calls and dual display of video programs and video calls, such as picture in picture.

Abstract: A processor in a television program delivery system receives programs watched information from terminals in a television delivery system. The processor arranges the programs watched information in a database or programs watched matrix so that the frequency of programs watched may be determined. The programs watched matrix may consist of time slots and program categories. The processor determines a program count for programs or program categories. The program count may then be used to send programming to the terminals. The terminals may provide the programs watched information in response to a cyclic polling message generated by the processor or by using a random access routine. The programs watched information may be provided over a cable or a telephone line.

Abstract: A method and an apparatus are used to target virtual objects to subscribers in a television delivery system. Programs are selected and virtual object locations are defined in the selected programs. The virtual objects available for targeting are categorized and the categories are correlated to viewing population information to determine the optimum targeting of the virtual objects. The virtual objects may be targeted based on information related to groups of subscribers. When a frame of a program includes a virtual object location, a default or an alternate virtual object is displayed. The virtual object location may change over space or time. The virtual object maybe interactive, and maybe used to link a subscriber to a remote location, such as an Internet web site.

Abstract: A rate generator for generating a plurality of different frequencies that represent video requests in a video on demand (VOD) system. The rate generator comprises a plurality of parallel groups, each group comprising a phase accumulator module having a plurality of phase accumulators, a phase increment model having a plurality of phase increment registers, and an adder, coupled to the phase accumulator module and the phase increment module. The adder sums the phase increment value from the phase from the phase increment module and the output of the phase accumulator module and provides the value back to the phase accumulator module. When the sum reaches a pre-determined value, the adder resets and generates a pulse at a frequency dependent on the phase increment and the sampling frequency. In addition, a method for deriving the rate generator architecture is also provided.

Abstract: A method and apparatus for compressing a plurality of video sequences, is provided where each sequence has information that is common with other video sequences. The ensemble encodes the video sequences into an MPEG compliant transport stream using less predicted frame information than separately encoding each video sequence. One illustrative application involves efficiently encoding and transmitting a user interface such as a program guide, interactive program guide, electronic program guide, navigator and the like. The user interface is illustratively embodied in an interactive program guide (IPG).

Abstract: 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).

Abstract: A method is disclosed for delivering television programming, including advertisements, to subscribers using a tiered video system. Advertisements or other video programs are associated with a plurality of channels, one or more of which may be used for programs. The user selects a program on a first channel for display on a television. The method switches the television from the first channel to a second channel having a video program, such as an advertisement. For example, the system displays programming from the first channel and displays an advertisement from a second channel during a commercial break in the program. After displaying the advertisement, the method switches the television channel back to the program channel. The channel switching is transparent to the user, and the advertisement may be a targeted selected from a group of advertisements to most closely associate with a profile of the subscriber stored in memory.
