Abstract

A multimedia server system and a method for communicating multimedia programming to distantly situated media control systems are disclosed. The multimedia server system includes a mass storage library for storing a plurality of multimedia programs. A multimedia program is coded in accordance with a predetermined compression standard and stored in a compressed digital format as sequentially ordered discrete program segments in the mass storage library, with each of program segments being representative of a unique portion of the multimedia program. A video parser organizes the sequentially ordered program segments of a multimedia program into a custom ordered series of program segments preferably including non-sequentially and sequentially ordered program segments in accordance with configuration parameters associated with the configuration and presentation control features of a media control system requesting the multimedia program. Concurrent transmission of a plurality of custom ordered series of program segments to a corresponding plurality of distantly located media control systems is facilitated by an asynchronous transfer mode distribution switch. The custom ordered series of program segments are processed by a local media control system to provide for the sequential presentation of the program segments on a local display and for providing local VCR-type control functions.

Claims

1. A server system for communicating multimedia programming to a distantly situated local media control system over a communication channel, the server system comprising:

a mass storage library for storing a plurality of multimedia programs, the multimedia programs being segmented into source program segments, and each of the source program segments representing a multimedia program portion;

an organizing unit that arranges the source program segments of a selected multimedia program into a custom ordered series of source program segments including non-sequentially ordered source program segments and sequentially ordered source program segments;

a transmission unit that transmits the source program segments of the custom ordered series to the communication channel;

a server controller that communicates with the local media control system and receives a configuration signal from the local media control system over the communication channel, the configuration signal being representative of configuration parameters associated with the local media control system; and

the organizing unit, in response to the configuration signal, organizing the source program segments into the custom ordered series of source program segments in accordance with the configuration parameters.

2. A system as claimed in claim 1, wherein:

the server system further comprises a coder that codes the source program segments defining the plurality of multimedia program stored in the mass storage library in accordance with a predetermined coding standard.

3. A system as claimed in claim 1, wherein the mass storage library includes either one of a digital storage device and a dynamic random access storage device for respectively storing the plurality of multimedia programs.

4. A system as claimed in claim 1, further comprising a segmenting unit that segments each of the plurality of multimedia programs into a corresponding series of sequentially ordered source program segments.

5. A system as claimed in claim 1, further comprising an indexing unit that associates a unique segment address with each of the source program segments.

6. A system as claimed in claim 1, further comprising a staging storage device, coupled to the organizing unit and the transmission unit that stores the custom ordered series of source program segments received from the organizing unit.

7. A system as claimed in claim 1, wherein the transmission unit transmits the source program segments arranged in packets to the communication channel, each of the packets comprising no greater than a predetermined maximum number of the source program segments.

8. A system as claimed in claim 1, wherein the transmission unit transmits the source program segments arranged in packets to the communication channel during transmission windows having a predetermined duration.

9. A system as claimed in claim 8, wherein the predetermined duration of the transmission windows is associated with the number of the source program segments arranged in the packets and the portion of the selected multimedia program represented by each of the source program segments arranged in the packets.

10. A system as claimed in claim 1, wherein the transmission unit comprises an asynchronous transmission mode switching unit that transmits a plurality of custom ordered series of source program segments representative of a corresponding plurality of multimedia programs asynchronously to a plurality of distantly situated local media control systems over the communication channel.

11. A server system for communicating multimedia programming to a distantly situated local media control system over a communication channel, the server system comprising:

a mass storage library for storing a plurality of multimedia programs each segmented into source program segments, each of the source program segments including a unique segment address and being representative of a portion of one of the plurality of multimedia programs;

an organizing device that arranges the unique segment addresses of source program segments associated with the one of the plurality of multimedia programs to produce a custom ordered series of source program segments;

a transmission device that transmits the custom ordered series of source program segments arranged in packets to the communication channel; and

wherein the organizing device arranges the unique segment addresses to produce a custom ordered series of source program segments including non-sequentially ordered source program segments.

12. A system as claimed in claim 11, further comprising a segmenting device that segments each of the plurality of multimedia programs into a corresponding series of sequentially ordered source program segments.

13. A system as claimed in claim 11, wherein the mass storage library includes either one of a digital storage device and a dynamic random access storage device for respectively storing the plurality of multimedia programs.

14. A system as claimed in claim 11, further comprising a staging storage device, coupled to the organizing device and the transmission device, for storing the custom ordered series of source program segments received from the organizing device.

15. A method for communicating a multimedia program from a remote multimedia server to a local media control system, the method comprising:

organizing sequentially ordered source program segments representative of the multimedia program into a custom ordered series of source program segments, the custom ordered series comprising non-sequentially ordered and sequentially ordered source program segments, and each program segment representing a unique portion of the multimedia program;

transmitting the source program segments of the custom ordered series to a communication channel; and

wherein the transmitting step includes the further step of transmitting the source program segments of the custom ordered series arranged in packets to the communication channel during transmission windows having a predetermined duration.

16. A method as claimed in claim 15, including the further step of segmenting the multimedia program into the sequentially ordered source program segments.

17. A method as claimed in claim 15, including the further step of selecting the multimedia program from a plurality of multimedia programs.

18. A method as claimed in claim 15, including the further step of coding the sequentially ordered source program segments in accordance with a predetermined coding standard.

19. A method as claimed in claim 15, wherein the predetermined duration of the transmission windows is associated with the number of source program segments arranged in the packets and the portion of the multimedia program represented by each of the source program segments arranged in the packets.

20. A method as claimed in claim 15, wherein the transmitting step includes the further step of transmitting the source program segments of the custom ordered series to the communication channel in accordance with an asynchronous transfer mode transmission methodology.
