This project was proposed by Robin Caine, vice chair of SC-02 through working group SC-02-02. It was approved under our rules by Subcommittee SC-02 and assigned to the working group SC-02-02 on digital input/output interfaces.
|TITLE||AES-X180, Amendment 5 to AES3, extensions to status data|
|SCOPE||This amendment adds a flag to indicate hidden data within a PCM signal, provides indications for two additional sampling frequencies, and clarifies the use of certain status bits when the signal is non-PCM.|
|OUTPUT INTENT||Amendment to standard|
|RATIONALE||Recent projects to support carriage of MPEG Surround data in an AES3 bitstream, as well as questions arising when considering non-PCM data in an AES3 signal, require some detailed changes to the AES3 specification.|
|WHO BENEFITS?||Advanced implementors and users of AES3 interfaces.|
|WHY AES?||The Audio Engineering Society is reponsible for controlling, maintaining and updating AES standards.|
