4. The apparatus of claim 1, wherein said controller is to monitor said encoding bit rate and said frame rate of said video stream, and to request said at least one video source to decrease said frame rate if said encoding bit rate of said video stream is low and said frame rate is high.

5. The apparatus of claim 1, wherein said controller is to control a wireless communication unit to transmit a feedback to said at least one video source, wherein said feedback includes said one or more attributes.

6. The apparatus of claim 1, wherein said one or more wireless video streams are to be transmitted over at least one link selected from the group consisting of a Wireless Fidelity (WiFi) link, a Wireless Display (WiDi) link, and a wireless gigabit (WiGig) Display Extension (WDE) link.

7. A system comprising:

a display to display one or more windows including video of one or more wireless video streams transmitted by one or more video sources;

at least one antenna to receive said one or more wireless video streams; and

a controller to control said one or more windows and to request at least one video source of said one or more video sources to set one or more attributes of a video stream transmitted by said at least one video source,

wherein said one or more attributes include at least one attribute selected from the group consisting of a resolution of said video stream, a frame rate of said video stream, an encoding bit rate of said video stream, and whether or not said video stream is to be transmitted,

and wherein said controller is to request said at least one video source to set the one or more attributes of the video stream based on a drop rate of the video stream, and to request said at least one video source to decrease said frame rate of said video stream if said encoding bit rate of said video stream decreases.

8. The system of claim 7, wherein said controller is to request said video source to set the encoding bit rate of said video stream based on the drop rate of said video stream.

9. The system of claim 8, wherein said controller is to request said at least one video source to increase said encoding bit rate of said video stream if said drop rate of said video stream is lesser than a first predefined threshold, and to decrease said encoding bit rate of said wireless video stream if said drop rate of said video stream is greater than a second predefined threshold.

10. The system of claim 7, wherein said controller is to monitor said encoding bit rate and said frame rate of said video stream, and to request said at least one video source to decrease said frame rate if said controller detects said encoding bit rate of said video stream is low and said frame rate is high.
