Abstract: Example methods and apparatus for adaptive video transmission based on channel capacity are disclosed. A first wireless display source device for adaptive video transmission based on channel capacity includes a video bit rate determiner, a comparer and a video bit rate setter. The video bit rate determiner is to determine a collective video bit rate based on a current number of wireless display connections in a peer-to-peer (P2P) group multiplied by a current video bit rate of the first wireless display source device. The P2P group includes a second wireless display source device in proximity to the first wireless display source device. The comparer is to compare the collective video bit rate to a wireless display capacity in proximity to the first wireless display source device. The video bit rate setter is to set the current video bit rate of the first wireless display source device to a first adjusted video bit rate value in response to the comparer determining that the collective video bit rate is greater than the wireless display capacity, and to set the current video bit rate of the first wireless display source device to a second adjusted video bit rate value in response to the comparer determining that the collective video bit rate is not greater than the wireless display capacity.

Abstract: Techniques related to adaptive bitrate streaming for wireless video are discussed. Such techniques may include determining candidate bitrates for encoding segments of a source video. A minimum of the candidate bitrates may be selected and a segment of the source video may be encoded based on the selected encoding bitrate. The encoded bitstream may be transmitted wirelessly from a transmitting device to a receiving device, which may decode the bitstream and present the decoded video to a user.

Abstract: A method for adaptive video transmission based on channel capacity. As part of the method, a first wireless display capacity in a proximity of a wireless display source device is determined. The first wireless display capacity is based on information that is received from a wireless channel scan associated with a formation of a (P2P) peer-to-peer group that includes the wireless display source device and a wireless display. Further, the video bit rate of one or more devices with wireless display connections in the proximity is determined, the video bit rate of the one or more devices with wireless display connections in the proximity is compared to the wireless capacity, and, based on the comparing, a video bit rate of the wireless display source device is set. A second wireless display capacity in the proximity of the wireless display source device is determined based on a wireless channel scan of a wireless channel to determine wireless display connections in the proximity.
