Abstract: A system and method for optimizing video for transmission on a device includes, in one example, the method includes capturing an original video frame and scaling the original video frame down to a lower resolution video frame. The lower resolution video frame is downscaled using a first encoder to produce a first layer output and the first layer output is decoded. The decoded first layer output is upscaled to match a resolution of the original video frame. A difference is obtained between the upscaled decoded first layer output and the original video frame. The difference is independently encoded using a second encoder to create a second layer output. The first and second layer outputs may be stored or sent to another device.

Abstract: An improved system and method are disclosed for providing virtual parallel access to a shared resource. In one example, the method includes receiving a request from a device to take control of the shared resource. After determining that another device is currently in control of the shared resource, a timer is started. Control of the shared resource will automatically pass from the device currently in control to the requesting device when the timer expires. Input received from the device currently in control is executed. Input received from the device that has requested control is buffered and executed once control is transferred.

Abstract: A system and method for managing a conference call using a selective transmission unit (STU) to manage multiple client devices participating in the conference call. In one example, the STU uses video transmission parameters and video reception parameters from each of the client devices to control which video streams are sent by the client devices to the STU. The STU then sends particular received video streams to each of the client devices based on the video reception parameters of the respective client device.
