Isochronous transmission providing method for use in standard wireless local area network transmission system, involves varying number of samples in audio frames to minimize buffer size in transmitter and receivers

摘要

#CMT# #/CMT# The method involves adjusting a contention-free isochronous audio traffic of a beacon interval to an optimum value, and reserving enough bandwidth for the audio traffic. A system delay is controlled and requirements are buffered. A maximum bandwidth for a contention-based traffic is assured, in addition to the contention-free isochronous audio traffic. Number of samples in audio frames is varied to minimize a buffer size in transmitter and receivers, where the samples in the audio frames are varied in a cycle of consecutive beacon intervals. #CMT# : #/CMT# Independent claims are also included for the following: (1) a wireless transmission system (2) an error correction method (3) a synchronization method for providing an isochronous transmission. #CMT#USE : #/CMT# Used for providing an isochronous transmission for streaming multi channel digital isochronous data e.g. audio data or video data, in a standard wireless local area network transmission system. #CMT#ADVANTAGE : #/CMT# The method allows for avoiding all error factors associated to a loudspeaker signal path, and for maximizing sound quality of the loudspeaker, without requiring connectors and differential signal transmitter/receivers for installation work, in a simple and cost effective manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block diagram of a standard wireless local area network transmission system. #CMT#INDUSTRIAL STANDARDS : #/CMT# The standard wireless local area network transmission system conforms to Institute of Electrical and Electronic Engineering (IEEE) 802.11g standards.
