Abstract: To allow a user to maximize use of a video and digital multimedia aggregator, a search suggestion engine and corresponding method may be used to provide suggestions of available content. The search suggestion engine starts by constructing a database of metadata elements or word items. The metadata element database may be constructed by using a crawler that periodically or continually crawls a content metadata database and extracts word items from the content metadata database. The word items are then processed according to a number of factors, including part-of-speech, entries in dictionaries and thesaurus and other factors. The thus-processed word items are indexed, and may be provided with a vector value. A subsequent search request submitted by the user may include search criteria that may be provided vector values. A processor within the search suggestion engine compares the vector values to determine if an indexed word item should be considered for retrieving the indexed word item's associated content.

Abstract: A device equipped with a camera and microphone includes the capability to send and receive video calls through a 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 indicates the occurrence of the communications event. The system also buffers the video program while paused, providing a user with replay capability. Alternatively, the system waits for a triggering event in order to pause the video program. The device may also include features for caller identification of video calls and dual display of video programs and video calls (e.g., picture in picture). A hardware upgrade for adding video call functionality to a device is also disclosed.

Upstream data reception hardware, databases and processing hardware and software, and corresponding features in a user's terminal are used to accomplish these functions.

Abstract: 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.

Abstract: Service resource items for use in call setup in a telephone system are held on servers that are connected to a computer network which is logically distinct from the telephone system infrastructure; this computer network may, for example, make use of the Internet. Each service item is locatable on the network at a corresponding URI and is associated with a particular telephone number. A mapping is provided between telephone numbers and the URIs of associated service resource items. When it is desired to access a service resource item associated with a particular telephone number, this mapping is used to retrieve the corresponding URI which is then used to access the desired service resource item.
