Adaptive wireless channel allocation for media distribution in a multi-user environment

摘要

Adaptive wireless channel allocation in a multi-user environment based on quality of received video streams. During the transmission of encoded media streams from a wireless access device to at least first and second video devices over a wireless channel, transmission windows are allocated in shared transmission frame intervals for transmission of media packets to the first and second video devices, respectively. Relative priorities are set/adjusted for the video devices based, at least in part, on one or more of the following: channel estimation information, reception characteristics, transmission acknowledgment information, video device characteristics and/or user feedback. The relative priorities are utilized to adaptively (re)allocate at least one portion of the transmission frame intervals. In addition to channel reallocation, the prioritization of devices may be utilized to adaptively alter the encoding bit rate of one or more media streams.

主权项

1. A method for transmitting media streams from a media server to a first client device and a second client device over a wireless channel during respective allocated portions of shared transmission frame intervals, comprising:
transmitting media packets to the first client device during a first allocated portion of a first transmission frame interval(s); transmitting media packets to the second client device during a second allocated portion of the first transmission frame interval(s); establishing relative priorities for the first and second client devices based on at least one of associated wireless channel estimation information, reception characteristics, transmission acknowledgment information, client device characteristics or user feedback; and reallocating, based on relative priorities, at least one portion of the first or second allocated portions of the transmission frame interval(s) to the other of the first or second allocated portions for further transmission of media packets by the media server during a subsequent transmission frame interval.
