Abstract

A multimedia system for rendering multimedia content in a portable device having an embedded processor. The portable device includes one or more rendering resources. A method is provided that performs operations of generating a multimedia object based on the multimedia content, associating a format handler with the multimedia object, and controlling a selected rendering resource using the format handler to render the multimedia content from the multimedia object.

Claims

1. A method for rendering multimedia content in a portable device having an embedded processor, the portable device further comprising one or more rendering resources, and the method comprising:

generating a multimedia object based on the multimedia content;

associating a format handler with the multimedia object; and

controlling a selected rendering resource using the format handler to render the multimedia content from the multimedia object.

2. The method of claim 1, further comprising generating a multimedia data structure based on the multimedia content.

3. The method of claim 1, wherein the step of controlling comprises:

implementing a state machine in the format handler to control the selected rendering resource; and

rendering the multimedia content using the state machine in the format handler.

4. A multimedia system for rendering multimedia content in a portable device having an embedded processor, the portable device further comprising one or more rendering resources, and the multimedia system comprising:

create media logic that operates to generate a multimedia object based on the multimedia content;

selection logic that operates to associate a format handler with the multimedia object; and

format handling logic that operates to control a selected rendering to render the multimedia content from the multimedia object.

5. The apparatus of claim 4, further comprising data structure logic to generate a multimedia data structure based on the multimedia content.

6. The apparatus of claim 5, wherein the format handling logic comprises:

logic to implement a state machine in the format handler to control the selected rendering resource; and

logic to render the multimedia content using the state machine in the formation handler.

7. A computer-readable medium containing computer-executable instructions for rendering multimedia content in a portable device having an embedded processor, the portable device further comprising one or more rendering resources, the instructions when executed perform a method, comprising:

generating a multimedia object based on the multimedia content;

associating a format handler with the multimedia object; and

controlling a selected rendering resource using the format handler to render the multimedia content from the multimedia object.

8. The method of claim 7, further comprising generating a multimedia data structure based on the multimedia content.

9. The method of claim 7, wherein the step of controlling comprises:

implementing a state machine in the format handler to control the selected rendering resource; and

rendering the multimedia content using the state machine in the formation handler.

10. A multimedia system for rendering multimedia content in a portable device having an embedded processor, the portable device further comprising one or more rendering resources, and the multimedia system comprising:

means for generating a multimedia object based on the multimedia content;

means for associating a format handler with the multimedia object; and

means for controlling a selected rendering resource using the format handler to render the multimedia content from the multimedia object.

11. The apparatus of claim 10, further comprising means for generating a multimedia data structure based on the multimedia content.

12. The apparatus of claim 10, wherein the means for controlling a selected rendering resource comprises:

means for implementing a state machine in the format handler to control the selected rendering resource; and

means for rendering the multimedia content using the state machine in the formation handler.

13. A multimedia system for rendering multimedia content in a portable device having an embedded processor, the portable device further comprising one or more rendering resources, and the multimedia system comprising:

one or more format handlers that operate to control the one or more rendering resources in the portable device; and

a creation utility that operates to create a multimedia object from the multimedia content and associate a selected format handler with the multimedia object, wherein the selected format handler renders the multimedia content from the multimedia object.

14. A method for rendering multimedia content in a portable device having an embedded processor, the portable device further comprising one or more rendering resources, and the method comprising:

encoding the multimedia content with media constructs;

transmitting the multimedia content to the portable device;

generating a multimedia object based on the media constructs;

associating a format handler with the multimedia object; and

controlling a selected rendering resource using the format handler to render the multimedia content from the multimedia object.
