Abstract

Machine-readable media, methods, and apparatus are described for a media playing tool with a multiple media playing model. In some embodiments, the multiple media playing model may decoding a first media stream into a plurality of first frames and decode a second media stream into a plurality of second frames. Further, the multiple media playing model may adjust a first frame of the plurality of first frames and a second frame of the plurality of second frames into a third frame with a predetermined layout.

Claims

1. A method comprising:

receiving two video streams at a host, said host coupled to a client;

determining whether said streams are to be displayed on said host or said client;

selectively converting said streams'"'"' formats, resolutions, positional relationships with respect to one another, and sizes depending on whether said streams are to be displayed on said host or said client; and

if said streams are to be displayed on said client, transmitting said streams to said client.

2. The method of claim 1 including:

decoding a first media stream into a plurality of first frames;

decoding a second media stream into a plurality of second frames; and

adjusting a first frame of the plurality of first frames and a second frame of the plurality of second frames into a third frame with a predetermined layout, wherein the third frame comprises a first sub-frame and a second sub-frame and the predetermined layout defines at least one of a positional relationship between the first sub-frame and the second sub-frame, a first resolution of the first sub-frame, and a second resolution of the second sub-frame.

3. The method of claim 2, wherein the adjusting further comprises:

resizing the first frame to generate a resized first frame based upon the first resolution of the first sub-frame;

resizing the second frame to generate a resized second frame based upon the second resolution of the second sub-frame; and

blending the resized first frame with the resized second frame based upon the positional relationship.

4. The method of claim 2, further comprising:

encoding the third frame to be transmitted to another computing platform.

5. The method of claim 2, further comprising:

playing the third frame at the computing platform.

6. An apparatus comprising:

a processor to receive two video streams at a host, said host coupled to a client, determine whether said streams are to be displayed on said host or said client, selectively convert said streams'"'"' formats, resolutions, positional relationships with respect to one another, and sizes depending on whether said streams are to be displayed on said host or said client; and

a storage coupled to said processor.

7. The apparatus of claim 6 said processor to:

decode a first media stream into a plurality of first frames;

decode a second media stream into a plurality of second frames; and

adjust a first frame of the plurality of first frames and a second frame of the plurality of second frames into a third frame with a predetermined layout, wherein the third frame comprise a sub-frame and the predetermined layout defines at least one of a positional relationship between the third frame and the sub-frame and a resolution of the sub-frame.

8. The apparatus of claim 7, adjust a first frame further comprises:

resize the second frame to generate a resized second frame based upon the resolution of the sub-frame; and

blend the first frame with the resized second frame based upon the positional relationship.

9. The apparatus of claim 7 including:

said processor to encode the third frame to be transmitted to another computing platform.

10. The apparatus of claim 7 including:

said processor to play the third frame at the computing platform.

11. One or more non-transitory computer readable media storing instructions executed by a processor to perform a method comprising:

receiving two video streams at a host, said host coupled to a client;

determining whether said streams are to be displayed on said host or said client;

selectively converting said streams'"'"' formats, resolutions, positional relationships with respect to one another, and sizes depending on whether said streams are to be displayed on said host or said client; and

if said streams are to be displayed on said client, transmitting said streams to said client.

12. The media of claim 11 said method including:

decoding a first media stream into a plurality of first frames;

decoding a second media stream into a plurality of second frames; and

adjusting a first frame of the plurality of first frames and a second frame of the plurality of second frames into a third frame with a predetermined layout, wherein the third frame comprises a first sub-frame and a second sub-frame and the predetermined layout defines at least one of a positional relationship between the first sub-frame and the second sub-frame, a first resolution of the first sub-frame, and a second resolution of the second sub-frame.

13. The media of claim 12, wherein the adjusting further comprises:

resizing the first frame to generate a resized first frame based upon the first resolution of the first sub-frame;

resizing the second frame to generate a resized second frame based upon the second resolution of the second sub-frame; and

blending the resized first frame with the resized second frame based upon the positional relationship.

14. The media of claim 12, further comprising:

encoding the third frame to be transmitted to another computing platform.

15. The media of claim 12, further comprising:

playing the third frame at the computing platform.
