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.

Bytes 18 to 21, Bits 0 to 7: According to John Ratcliff’s Timecode: A low-quality auxiliary channel used as specified in the channel status word, notably for producer talkback or recording studio -to-studio communication. At the highest level, each consecutive frames are grouped into an audio block. Of the physical interconnection types defined by IECthree are in common use.

The 8-bit preambles are transmitted in time allocated to the first four time slots of each subframe time slots 0 to 3.
A value of all zeros for 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. These are essentially consumer versions of AES3 for use within the domestic high fidelity environment using connectors more commonly found in the consumer market. This page was last edited on 25 Novemberat Frames contain 64 time slots and are produced once per sample time.
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. One sample stored with most significant bit MSB last.
During the presence of defective samples, the receiving ief may be instructed to mute its output. Therefore, no need to order amendments in addition jec this publication. This third edition of IEC cancels and replaces the second edition published in and constitutes a technical revision. Any of the three marks the beginning of a subframe. Bits from each frame of an audio block are collated giving a bit channel status word. Two subframes A and B, normally used for left and right audio channels make a frame.
For information on the synchronization of digital audio structures, see the AES11 standard. This bilingual version corresponds to the monolingual English version, publishedin An AES3 signal can carry two channels of PCM audio over several transmission media including balanced linesunbalanced linesand optical fiber.
As stated before there is one channel status bit in each subframe, making one bit word for each channel in each block. We recommend that you check the website of the publishers of the international document before making a purchase.
Type I connections are most often used in professional installations and are considered the AES3 standard connector. While samples repeat each frame time, metadata is only transmitted once per audio block. 60598-3 is important to us that you purchase the right document. Variants using different physical connections are specified in IEC Forms a serial data stream for each channel with 1 bit per framewith a format specified in the channel status word.
In the case of AES3, the standard describes in detail how the bits have to be used.
IS/IEC 60958-3: Digital audio interface, Part 3: Consumer applications
60958- is the time-of-day laid down during the source encoding of the signal and shall remain unchanged during subsequent operations. A user’s guideit is embedded as a bit binary word in bytes 18 to 21 of the channel status data. The development of standards for digital audio interconnect for both professional and domestic audio equipment, began in the late s  in a joint effort between the Audio Engineering Society and the European Broadcasting Union, and culminated in the publishing of AES3 in 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.
