Abstract

The invention relates to an audio/visual system for providing network connectivity to a common embedded interface by simulating the embedded interface. The audio/visual system is coupled to a computer that has at least one memory, and comprises a rendering circuit having a memory and an emulation circuit that is coupled to the rendering circuit. The emulation circuit comprises a memory for storing instruction sequences and a processor coupled to the memory, that executes the stored instruction sequences. The audio/visual system further comprises an audio/visual apparatus coupled to the rendering circuit and the emulation circuit, and a display coupled to the rendering circuit. The stored instruction sequences cause the processor to (a) retrieve information stored in one of the memory of the audio/visual apparatus or the memory of the computer; (b) forward the information to the rendering circuit for processing; (c) forward the processed information to the display; and (d) display the processed information. Various embodiments are described.

Claims

1. An audio/visual system comprising:

a. an audio/visual device subsystem;

b. a user interface facilitating operation of the device subsystem and selection of content;

c. a rendering circuit facilitating presentation of selected content on the audio/visual system in a digital format native to the audio/visual system; and

d. an emulation circuit facilitating receipt of a content selection via the user interface, determining if the content resides on the device subsystem in the digital native format and, if not, obtaining the content from another source in a format other than the digital native format, converting the content into the digital native format and providing the converted content to rendering circuit for presentation, the emulation circuit thereby facilitating the rendering of the received content by the rendering circuit as if the content was retrieved from the device subsystem in the digital native format.

2. The system of claim 1 wherein the audio/visual system further comprises a drive.

3. The system of claim 1 wherein the another source is a computer.

4. The system of claim 3 wherein the computer is connected to the audio/visual system via a computer network.

5. The system of claim 4 wherein the computer network is selected from a group consisting of:

a global computer network, a local area network, and a wide area network.

6. The system of claim 4 further comprising a memory for storing content retrieved from said computer network on said audio/visual system.

7. The system of claim 4 wherein the emulation circuit transcodes information retrieved from said computer network.

8. The system of claim 4 wherein the emulation circuit further includes stored instruction sequences to control data flow through the audio/visual system based on at least one of the following parameters:

at least one parameter of said computer network, at least one parameter of a target device in said computer network, an output display requirement of said audio/visual system, a data type of said content and a data characteristic of said content.

9. The system of claim 8 wherein said at least one parameter of said target device is one or more of the following:

a bandwidth of said target device, and a storage size of said target device.

10. The system of claim 8 wherein the emulation circuit further includes stored instruction sequences to control data flow through the audio/visual system by providing a handshake protocol based on said at least one parameter of said computer network, to optimize data flow.

11. The system of claim 3 wherein the computer is directly connected to the audio/visual system.

12. The system of claim 1 wherein said audio/visual device subsystem is selected from a group consisting of a digital versatile disk system, a digital video cassette recorder, an audio presentation device and a television.

13. The system of claim 1 wherein the rendering circuit decompresses said content prior to presentation.

14. The system of claim 1 wherein the rendering circuit formats said content prior to presentation.

15. The system of claim 1 wherein the emulation circuit further packetizes said content for distribution to a home network system.

16. The system of claim 1 further comprising a remote control, said remote control to issue a control signal that is converted by said audio/visual system to a network command for retrieving said content.

17. The system of claim 1 wherein said audio/visual system is coupled to a network comprising a plurality of audio/visual apparatuses, and said emulation circuit retrieving said content from one of said plurality of audio/visual apparatuses.

18. A method of facilitating selection and display of media content on a player device comprising a device subsystem for presenting media content in a digital format native to the player device including a user interface adapted to operate the device and facilitating selection of content thereon, the method comprising the steps of:

a. receiving a content selection via the user interface and determining if the content is accessible via the device subsystem in the digital native format;

b. if so, reading the content from the device subsystem, rendering the content for presentation in the digital native format on the player device and displaying the content on the player device;

c. if not, obtaining the content from another source in a format other than the digital native format, converting the content into the digital native format, rendering the content as though read from the device subsystem of the player device in the digital native format, and displaying the content on the player device.

19. The method of claim 18 wherein the content is obtained from another source via a computer network.

20. The method of claim 19 further comprising transmitting the content retrieved from said network to a computer for remote storage.

21. The method of claim 19 wherein the computer network is selected from a group consisting of:

a global computer network, a local area network, and a wide area network.

22. The method of claim 19 further comprising storing content retrieved from said computer network in a memory device residing on said player device.

23. The method of claim 19 further comprising transcoding said content retrieved from said computer network.

24. The method of claim 19 further comprising controlling data flow in said player device, based on at least one of the following parameters:

at least one parameter of said computer network, at least one parameter of a target device in said computer network, an output display requirement of said player device, a data type of said content and a data characteristic of said content.

25. The method of claim 24 wherein said at least one parameter of said target device is one or more of the following:

a bandwidth of said target device, and a storage size of said target device.

26. The method of claim 24, wherein controlling data flow further comprises providing a handshake protocol based on said at least one parameter of said computer network to optimize data flow.

27. The method of claim 18 wherein said player device is selected from a group consisting of a digital versatile disk system, a digital video cassette recorder, an audio presentation device and a television.

28. The method of claim 18 further comprising decompressing said content prior to presentation of said content.

29. The method of claim 18 further comprising formatting said content prior to presentation of said content.

30. The method of claim 18 further comprising packetizing said content for distribution to a home network system.

31. The method of claim 18 further comprising receiving a control signal from a remote control, said control signal being converted by said player device to a network command for retrieving said content.
