摘要： The present invention provides a system and method for affiliating a wireless device with a wireless local area network (WLAN). An embodiment of the method of this invention comprises establishing, at a control node of the WLAN, access frequency(s) for affiliation with the WLAN. The control node periodically provides a beacon frame on the access frequency(s) that indicates the timing of affiliation with the WLAN. The wireless device determines the access frequency(s) for affiliating with the WLAN and the timing of affiliation with the WLAN based on the beacon frame. The wireless device provides self identification information via the access frequency during the beacon frame. This allows the control node to determine the access privileges of the wireless device based on the identification information. Finally, the control node affiliates the wireless device with an initial access channel from a set of access channels in accordance with the access privileges.

摘要： A method and apparatus for dynamic data rate adjustment of a wireless transport channel include processing that begins with one of a plurality of client modules within a wireless multimedia system monitors channel characteristics of a wireless transport channel. The monitoring is done at or below a received packet rate to determine variations in the channel characteristics on a packet-by-packet basis or on a group-of-packets by group-of packets basis. The processing continues when the client module determines whether the variations in the channel characteristics affect the data rate of data contained in the packets received via the wireless transport channel. When the variations in the channel characteristics affect the data rate, the client module provides data rate adjustment feedback to a multimedia server of the wireless multimedia system via the wireless transport channel. The processing continues when the multimedia server adjusts the data rate of the data contained in the packets being transported via the wireless transport channel in accordance with the data rate adjustment feedback.

摘要： Audio video synchronization begins by receiving an audio-video signal via a first communication path. The processing continues by capturing a representation of an audio component of the audio-video signal, wherein the audio component was rendered audible via a second communication path. The processing continues by deriving a reference representation of the audio component of the audio-video signal received via the first communication path. The processing continues by aligning a video component of the audio video-signal of the first communication path with the audio component of the audio video signal of the second communication path based on the representation of the audio component and the reference representation of the audio component.
