Abstract

A high capacity interactive multimedia system is provided that can deliver large number of concurrent video on demand and high speed data streams in an integrated fashion to a plurality of subscribers located at one or more subscriber sites. A video server module in the system generates a plurality of video on demand streams, which are transported via a high capacity transport system to a plurality of clients located at a subscriber site. A web server in the system stores data, such as web pages, which are also transported via the high capacity transport system to the clients. By accessing the web pages, a plurality of subscribers interact with the system via the clients. The interactive multimedia system controls and monitors in a centralized fashion the hardware and software components of the system, thus assuring the quality of the video and data services provided to the subscribers.

Claims

1. A system, comprising:

a video server that includes;

a set of storage devices;

a plurality of nodes configured to stream a plurality of video streams from a video title, the video title divided into segments stored in the set of storage devices, each of the plurality of nodes comprising a processor, each of the processors running a video server program configured to combine the segments stored in the set of storage devices into the plurality of video streams and to stream the plurality of video streams, and the processors all having concurrent access to said set of storage devices for concurrently streaming the plurality of video streams;

a transport system to transport the plurality of video streams from the video server to a plurality of client devices; and

a system controller configured to monitor the video server and client devices, wherein the monitoring includes sending echo messages to the video server, determining a fault condition when the video server does not respond to at least one of the echo messages, and displaying a color coded fault indication on a display of the system controller.

2. The system of claim 1, wherein the segments are stored throughout the set of storage devices.

3. The system of claim 1, wherein each of the plurality of client devices is configured to receive at least some of the plurality of video streams.

4. The system of claim 3, wherein the plurality of client devices includes at least one of a set top box or a personal computer.

5. The system of claim 1, further comprising:

an encoder for encoding video and for storing the encoded video in the video server.

6. The system of claim 5, wherein the encoder comprises a real-time encoder for encoding real-time video.

7. The system of claim 5, wherein the encoder comprises an off-line encoder for encoding off-line video.

8. The system of claim 1, further comprising a web server to store data and send the data via the transport system to the plurality of client devices.

9. The system of claim 8, wherein each of the plurality of client devices comprises:

a browser program to retrieve the data from the web server;

a video client program to receive one of the video streams and control the video stream; and

a processor to execute the browser program and the video client program.

10. The system of claim 8, wherein the web server interfaces an Internet Protocol (IP) network.

11. The system of claim 8, wherein the data is in Hypertext Markup Language (HTML) format.

12. The system of claim 1, wherein each of the plurality of nodes further comprises:

an interface module configured to format the video streams into packets and transmit the packets on the transport system; and

a disk controller configured to retrieve the video titles from the set of storage devices.

13. The system of claim 1, wherein the transport system includes one or more asynchronous transfer mode (ATM) networks.

14. The system of claim 13, wherein the transport system includes pre-established connections associated with the plurality of client devices, respectively.

15. The system of claim 1, wherein the video server program configures a video session with the plurality of client devices by mapping an IP address of each of the plurality of client devices to a network address of the client device.

16. A method comprising:

receiving at a video server a plurality of requests initiated by each of a plurality of client devices to receive one or more video titles, the one or more video titles each divided into segments and stored in a set of storage devices;

streaming by a plurality of nodes of the video server a plurality of video streams corresponding to the one or more video titles, wherein the plurality of video streams are formed by combining the segments stored in the set of storage devices, wherein each of the plurality of nodes comprises a processor having concurrent access to the set of storage devices, and wherein the plurality of video streams are streamed concurrently;

transporting the plurality of video streams via a transport system;

monitoring the video server at a system controller by sending echo messages to the video server;

determining a fault condition when the video server does not respond to at least one of the echo messages; and

displaying a color coded fault indication on a display of the system controller.

17. The method of claim 16, wherein the segments are stored throughout the set of storage devices.

18. The method of claim 16, further comprising:

receiving each of the plurality of video streams at a respective requesting client of the plurality of plurality of client devices.

19. The method of claim 16, further comprising:

encoding video received from a video input; and

storing the encoded video as the video title in the video server.

20. The method of claim 19, wherein the encoding comprises at least one of encoding real-time video or encoding off-line video.

21. The method of claim 16, further comprising:

configuring a video session with each of the plurality of client devices by mapping an IP address of each of the plurality of client devices to a network address associated with said client device.

22. The method of claim 16, wherein receiving the plurality of requests initiated by each of a plurality of client devices includes:

transmitting by a web server to the plurality of client devices a graphical user interface including a number of indications corresponding to the one or more video titles;

receiving by the web server selections from the plurality of client devices of the one or more video titles; and

sending the plurality of requests from the web server to the video server, each of the plurality of requests including an identifier of a selected video title.

23. The method of claim 16, further comprising:

receiving at the video server from the plurality of client devices one or more control commands; and

adjusting the streaming of the plurality of video streams in accordance with the one or more control commands;

wherein the one or more control commands include at least one of a play, forward, reverse, stop and pause command.
