thereof via an iec 958 protocolled interface for use in a multi channel audio reproduction apparatus for each respective audio channel mpeg audio samples are packaged recurrently in burst payloads and these burst payloads are packaged as user data in iec958 format frames pause bursts are used for signalling absence of audio for all associated channels with each pause burst representing such audio absence during a perceptibly acceptable time interval only application_number US 201313940404 A description for better detailing the invention first various applicable information formats are described fig1 shows the iec958 format which according to the upper diagram consists of a concatenation of frames grouped into blocks of 192 frames each the second diagram shows each frame to consist of two sub frames the first frame of a block has subframes labelled b left and w right further subframes are all labelled m the third diagram shows the setup of a subframe as shown it has four preamble bits four auxiliary bits four unused bits sixteen data bits or bitstream and four flag bits v u c p the flag bits indicate the following v indicates no deviation from the standard u indicates user data with u2018 0 u2019 default c contains one bit of a channel status word and p is a parity bit relating to bits 4 through 31 a pair of subframes may contain one pcm word from each of left and right channels according to the present invention for consumer applications the channel status word as built from.
