IEC +AMD+AMD CSV Standard | Digital audio interface – Part 3: Consumer applications. IEC (formerly IEC ) is the International Electrotechnical Commission’s standard on digital audio interfaces. It consists of several parts: IEC General; IEC Software Information Delivery Mode; IEC Consumer. IEC Digital audio interface – Part 3: Consumer applications.

No attempt was made to use a carrier able to support both rates; instead, AES3 allows the data to be run at any rate, and encoding the clock and the data together using biphase mark code BMC. Archived from the original on Consumer applications This document has been re-assessed by the committee, and judged to still be up to date.
For information on the synchronization of digital audio structures, see the AES11 standard. This third edition of IEC cancels and replaces the second edition published in and constitutes a technical revision. Even parity bit for detection of errors in data transmission.

Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the latest version of a document, including where it has not yet been provided through an international feed.
This bilingual version corresponds to lec monolingual English version, publishedin During the presence of defective samples, the receiving equipment may be instructed to mute its output.
An AES3 signal can carry two channels of 06958-3 audio over several transmission media including balanced linesunbalanced linesand optical fiber. A low-quality auxiliary channel used as specified in the channel status word, notably for producer talkback or recording studio -to-studio communication.
Of the physical interconnection types defined by IEC irc, three are in common use.
Two subframes A and B, normally used for left and right audio channels make a frame. The standard was first published in and was revised in and It can be used for synchronization and for logging and identifying audio content. A value of all zeros 6095-83 the binary sample address code shall, for the purposes of transcoding to real time, or to time codes in particular, be taken as midnight i.

Transcoding of the binary number to any conventional time code requires accurate sampling frequency information to provide the sample accurate time. Type I connections use balanced3-conductor, 69058-3 twisted pair cabling with XLR connectors.
Retrieved from ” https: The development of standards for digital audio interconnect for both professional and domestic audio equipment, began in the late s  in a joint 60958- between the Audio Engineering Society and the European Broadcasting Union, and culminated in the publishing of AES3 in This is the time-of-day laid down during the source encoding of the signal and shall remain unchanged during subsequent operations.
If the auxiliary sample is used, bits 4—7 are not included. Here is a summary of the channel status word: It is used by most CD players to indicate that concealment rather than error correction is taking place. Data with smaller sample bit depths always have MSB at bit 27 and are zero-extended towards the least significant bit LSB.
BS EN +A – Digital audio interface. Consumer applications
Forms a serial data stream for each channel with 1 bit per framewith a format specified in the channel status word. It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be used. This determines the clock rate. A user’s guideit is embedded as a bit binary word in bytes 18 to 21 of the channel status data.
