Abstract

The present disclosure relates to rendering and recording multimedia content at a computer. The multimedia content may be streamed from a source such as an Internet website, received at the computer, and rendered by the computer. The rendering may include recording the multimedia content if the computer is so authorized by adding a recording component to a linked set of components or filters that perform the rendering of the multimedia content. If the computer is not authorized to record the multimedia content, the recording component is disabled or left out; however, the multimedia content may be processed and rendered through the linked set of components without the recording component.

5. The method of claim 1 wherein the creating comprises components to render the multimedia content whether providing a recording component is performed or not.

6. The method of claim 1 wherein the creating is performed for every instance multimedia content is received.

8. The method of claim 1 wherein the determining authority is based on a predetermined protocol with the source.

9. The method of claim 8 wherein the predetermined protocol is based on encryption and decryption keys shared with the source.

10. The method of claim 1 wherein the providing the recording component is omitted if not authorized to record the multimedia content.

11. The method of claim 1 wherein the providing a recording component comprises a writer component connected to the recording component which stores the multimedia content to a local storage device.

12. The method of claim 11 wherein the multiplexes audio and video content.

13. The method of claim 11 wherein the writer component compresses the multimedia prior to storing to the local storage device.

14. The method of claim 11 wherein the write component makes use of a predetermined protocol to store the multimedia content to the local storage device, where the predetermined protocol is used to play back the multimedia content.

15. The method of claim 1 wherein the providing is based on the recording component being registered to be installed in the linked set of components.

16. The method of claim 1 further comprising establishing a user interface component to the recording component.

17. The method of claim 16 wherein the user interface component provides status as to recording and rendering states.

18. The method of claim 16 wherein the user interface component is part of a media player that comprises the linked set of components.

19. The method of claim 16 wherein the user interface component is external to a media player that comprises the linked set of components.

20. A personal computer that performs the method of claim 1.

7. The method of claim 7 wherein the linked set of components is destroyed once rendering is complete.

21. A method comprising:

receiving a stream of multimedia content from a source;

separating the streamed multimedia content into audio content and video content;

initiating a first linked set of components to process the audio content, and a second linked set of components to process the video content;

creating a first recording component in the first linked set of components to record the audio content if authorized, and a second recording component in the second linked set of components to record video content if authorized; and

providing audio output from the first linked set of components and video output from the second linked set of components.

22. The method of claim 21 wherein the receiving the stream of multimedia content is from a separate source on a network.

23. The method of claim 21 wherein the receiving the stream of multimedia content is from an Internet source.

24. The method of claim 21 wherein the receiving the stream comprises protected multimedia content.

25. The method of claim 21 wherein the creating is performed based on registration of the first recording component as authorized to record audio content, and registration of the second recording component as authorized to record video content.

26. The method of claim 25 wherein the creating of first and second recording components is based on a predetermined protocol to allow recording of audio and video content.

27. The method of claim 25 wherein the creating of the first recording component as authorized to record if audio content is not protected, and creating the second recording component as authorized if video content is not protected.

28. The method of claim 25 wherein the creation of the first recording component as authorized to record if a predetermined protocol is established to allow audio content to be copied, and creation of the second recording component as authorized if the predetermined protocol is established to allow video content to be copied.

29. A computer comprising:

means for receiving streaming multimedia content;

means for rendering the streaming multimedia content;

means for storing the streaming multimedia content if so authorized; and

means for playing back the stored multimedia content.
