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: As stated before there is one channel status bit in each subframe, making one bit word for each channel in each block. Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the kec version of a document, including where it has not yet been provided through an international feed.
It is important to us that you purchase the right document. Of the physical interconnection types defined by IECthree are in common use.
It includes the following changes: A synchronisation preamble biphase mark code violation for audio blocks, frames, and subframes.
These are essentially consumer versions of AES3 for use within the domestic high fidelity environment using connectors more commonly found in the consumer market. Forms a serial data stream for each channel with 1 bit per framewith a format specified in the channel status word.
This uses the same cabling, patching and infrastructure as analogue or digital video, and is thus common in the broadcast industry. It can be used for synchronization and for logging and identifying audio content. During the presence of defective samples, the receiving equipment may be instructed to mute its output.
This bilingual version corresponds to the monolingual English version, publishedin LSBs uec transmitted first.

At the highest level, each consecutive frames are grouped into an audio block. If you need help with the purchase or have any queries please email enquiries standards. Therefore, no need to order amendments in addition to this publication. Consumer applications This document has been re-assessed by the committee, and judged to still be up to 6058-3.
If the auxiliary sample is used, bits 4—7 are not included. 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 List of International Electrotechnical Commission standards.
This third edition of IEC cancels and replaces the ice edition published in and constitutes a technical revision. In the case of AES3, the standard describes in detail how the bits have to be used.
Time of day sample address code. Data with smaller sample bit depths always have MSB at bit 27 and are zero-extended towards the least significant bit LSB. While samples repeat each frame time, metadata is only transmitted once per audio block.

IS/IEC 60958-3: Digital audio interface, Part 3: Consumer applications
We recommend that you 609588-3 the website of the publishers of the international document before making a purchase. Views Read Edit View history. An AES3 signal can carry two channels of PCM audio over several transmission media including balanced linesunbalanced linesand optical fiber. Default value shall be logic “0”. This determines the clock rate. A user’s guideit is embedded as a bit binary word in bytes 18 to 21 of ie channel status data.
Bits from each frame of an audio block are collated giving a bit channel status word. The 8-bit preambles are transmitted in time allocated to the first four time slots of each subframe time slots 0 to 3. One sample stored with most significant 60958–3 MSB last.

Two subframes A and B, normally used for left and right audio channels make a frame. It is used by most CD players to indicate that concealment rather than error correction is taking place. A low-quality auxiliary channel used as specified in the channel status word, notably for producer talkback or recording studio -to-studio communication. This is the time-of-day laid down 609958-3 the source encoding of the signal and shall remain unchanged during subsequent operations.

For information on the synchronization of digital audio structures, see the AES11 standard. This consolidated version consists of the third edition ,its amendment 1 and its amendment 2 The hardware interface is usually implemented using RS line eic and receivers. International Classification for Standards ICS is an international classification system 60958- technical standards. Type I connections are most often used in professional installations and are considered the AES3 standard connector.
