EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60958 testing. IEC EN 60958 defines a serial, unidirectional, auto-clocked interface for interconnection of digital audio equipment for consumer and professional applications. It provides the basic structure of the interface. Separate documents describe items specific to certain applications. The interface is primarily designed to carry monophonic or stereophonic programs, encoded using linear PCM and with a resolution of up to 24 bits per sample.
When used for other purposes, the interface may carry encoded audio data other than linear PCM encoded audio samples. The interface is also allowed to carry data related to computer software, multimedia technologies or signals encoded using non-linear PCM. The format specification for these applications is not part of this document. The interface is designed to operate at sound sampling frequencies of 32 kHz and above.
Prefaces are special patterns that enable the synchronization and identification of subframes and blocks. In order to achieve synchronization within a sampling period and make this process completely reliable, these models violate the biphasic signed code rules, thus eliminating the possibility of spoofing preambles of data.
The channel status for each subframe provides information about the data carried in the main data area of the same subframe. The specific organization depends on the application. In comments, the "0" suffix denotes the first byte or bit. Where channel status bits are combined to form non-binary values, the least significant bit should be transmitted first, unless otherwise specified.
