35、ACE Part 3: Consumer applications 1 Scope This part of IEC 60958 specifies the consumer application of the interface for the inter- connection of digital audio equipment defined in IEC 60958-1. NOTE When used in a consumer digital processing environment, the interface is primarily intended to carry
36、stereophonic programmes, with a resolution of up to 20 bits per sample, an extension to 24 bits per sample being possible. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undat

39、nt, the terms and definitions given in IEC 60958-1 apply. 4 Interface format The interface format as defined in IEC 60958-1 shall be used. Unless otherwise specified in the annexes, the following specification is applicable. Audio sample word has a length of 20 bits/sample. The auxiliary sample bits
40、 are an optional expansion of the audio sample, if not used = “0”. User data is not used, all bits = “0”. Channel status is identical for both subframes of the interface, with the exception of the channel number, if that is not equal to zero. Licensed Copy: London South Bank University, London South

Channel status information is organized
42、in a 192-bit block, subdivided into 24 bytes, numbered 0 to 23 (see Table 1). The first bit of each channel status block is carried in the frame with preamble “B”. The individual bits of a channel status block are numbered 0 to 191. The primary application is indicated by channel status bit 0. As st
43、ated in IEC 60958-1, for the consumer digital audio applications described in this standard, this first channel status bit equals “0”. NOTE As stated in IEC 60958-1, for professional application this first channel status bit equals “1”. Secondary applications may be defined within the framework of t
44、hese primary applications. 5.2 Application 5.2.1 Channel status general format For each channel, the channel status block provides the information described in this clause and summarized in Table1.
