Abstract

A video on demand system includes a head-end coupled through a proxy server to plural client terminals. The proxy server performs (or cooperates with another component in performing) various functions, including user interface definition, security, system administration (e.g. channel management, load distribution, and failover), and protocol translation.

Claims

1. In a video-on-demand application including plural user terminals and an infrastructure linking the terminals to one or more video servers, a method comprising:

presenting a user interface on a screen associated with one of said terminals, the user interface comprising plural elements;

specifying a first group of user interface elements in accordance with first instructions stored in the user terminal; and

specifying a second group of user interface elements in accordance with second instructions received by the user terminal from the infrastructure, wherein the user interface elements of the first and second groups allow the user to input commands;

wherein the infrastructure further comprises a head end and a proxy server, the proxy server positioned between the plural user terminals and the one or more video servers so that communications pass from the one or more video servers through the proxy server to the plural user terminals;

the proxy server comprising a control point for administering the second group of user interface elements on the plural client terminals so that the first and second groups of user interface elements are shared between the user terminal and the proxy server for displaying the shared user elements on the user terminal, the first group of user interface elements including a play button and the second group of user interface elements including a control, the play button and the control forming a portion of the user interface on the screen so that the user interface includes a combination of user interface elements provided by both the user terminal and the proxy server, and the method further comprises;

receiving a video-selection via a graphical control presented on the screen, the video-selection made from among plural videos presented for selection as provided from a library of available videos maintained at the proxy server, the proxy server maintaining the library based on communications with the head end data;

the graphical control comprising an element of the second group of user interface elements sent from the proxy server.

2. The method of claim 1 wherein the first and second user interface elements are presented at different times.

3. The method of claim 1 wherein the second instructions include graphic data, the method including using said graphic data for logo branding of the user interface.

4. The method of claim 1 comprising interrupting delivery of an on-demand video in response to a user command input through one of said first group of user interface elements, and presenting a screen display including at least one of said second group of user interface elements in response.

5. The method of claim 4 wherein said screen display indicates whether the viewer has electronic mail waiting.

6. The method of claim 4 wherein said screen display indicates time remaining for the interrupted on-demand video.

7. The method of claim 1 wherein the graphical control presented on screen is provided via HTML instructions sent to a set-top box coupled to the screen, wherein the HTML instructions are sent to the set-top box from the proxy server for rendering user interface screens and controls.

8. The method of claim 1 wherein a new user interface element is added to the second group of user interface elements and the new user interface element is sent by the proxy server and presented on the screen.

9. The method of claim 8, wherein the new user interface element added to the second group of user interface elements comprises a button, a control, a graphic element, or a label.

10. The method of claim 1 wherein the proxy server dynamically changes a logo as it appears at plural user terminals.

11. The method of claim 1 wherein the first group of user interface elements comprise play controls for video-on-demand and the second group of user interface elements further comprise an indication that a viewer has electronic mail waiting.

12. A video on-demand system comprising a screen coupled to a set-top box, a remote control controlling the set-top box, a remote head-end comprising video entertainment, and a proxy server interposed between the set-top box and the remote head end so that the video entertainment passes from the remote head-end to the proxy server and the proxy server delivers the video entertainment to the set-top box, the video on-demand system further comprising:

a user interface presented on the screen;

the presented user interface specified via textual mark-up language elements comprising a first group and a second group of textual mark-up language elements;

the first group of textual mark-up language elements stored in the set-top box; and

the second group of textual mark-up language elements stored in the proxy server and sent to the set-top so that the first and second groups of textual mark-up language elements are shared between the set-top box and the proxy server so that some of the textual mark-up language elements are supplied from the proxy server and some from the user terminal so that the combination of textual mark-up language elements from the proxy server and textual mark-up language elements from the set-top box together form the user interface presented on the screen, the textual mark-up language elements from the set-top box including a first selectable button and the textual mark-up language elements from the proxy server including a second selectable button.

13. The video on-demand system of claim 12 wherein a graphical control specified via the second group is activated on the screen via the remote control to provided a video-selection, the video-selection made from plural available videos provided from a library of available videos maintained at the proxy server, the proxy server maintaining the library based on communications with the head end data.

14. The video on-demand system of claim 13 wherein the proxy server adds a new element to the second group, and the set-top box receives and displays the new element as specified.

15. One or more computer readable storage device comprising computer-executable instructions of a distributed video-on-demand application, the distributed video-on-demand application facilitating video-on-demand for plural user terminals, a head-end, and a proxy server positioned between the head-end and the plural user terminals, the computer-executable instructions comprising:

instructions for presenting a user interface on a screen associated a user terminal, the user interface comprising plural elements;

instructions for specifying a first group of user interface elements in accordance with first instructions stored in the user terminal; and

instructions for specifying a second group of user interface elements in accordance with second instructions received by the user terminal from the proxy server so that the first and second groups of user interface elements are shared between the user terminal and the proxy server for displaying the shared elements on the user terminal.

16. The computer readable storage device of claim 15 wherein the computer-executable instructions specifying the first group of user interface elements include play controls for video-on-demand, and the computer-executable instructions for specifying the second group of user interface elements include controls for video-on-demand selection.

17. The computer readable storage device of claim 15 wherein the computer-executable instructions specifying the second group further comprise a graphical element presented on the screen, the graphical element presented for receiving a selection from among plural selectable video programs, the plural selectable video programs provided from a library of available video programs maintained at the proxy server, the proxy server maintaining the library based on communications with the head end, the communications indicating available video programming at the head-end, and wherein a specification of the graphical element is sent to the user terminal from the proxy server.
