摘要： A digital video apparatus provides reduced channel change times. According to an exemplary embodiment, the digital video apparatus includes at least one receiver for receiving first and second video streams representing the same program, wherein the first video stream has at least one characteristic different from the second video stream; a first signal processor for processing the first video stream to generate a first processed video stream; a second signal processor for processing the second video stream to generate a second processed video stream having a delay with respect to the first processed video stream; a renderer for rendering the second processed video stream responsive to a channel change command; and a switch for switching from the second processed video stream to the first processed video stream after the renderer begins rendering the second processed video stream, and thereby causing the renderer to begin rendering the first processed video stream.

摘要： A network information delivery system automatically determines end-user information output requirements based on predetermined data corresponding to each requesting end-user terminal. A user profile is maintained in a database either associated with a network information delivery system or with the end-user terminal and is accessed by the network information delivery device. If the network information delivery device has authority to access the end-user terminal, a program may be downloaded to the end-user terminal to determine the exact end-user terminal configuration. The program executing in the end-user terminal returns to the network information delivery device a user profile containing the end-user terminal capabilities so that the requested information may be formatted and delivered to the end-user in an optimal manner. The information to be delivered to end-users may be pre-stored in predetermined formats. The predetermined formats may be determined based on a volume of requests and the characteristic of the information. The information may also be stored in a generic format so that packaging the information for a specific user may be efficiently and timely performed.
