BS EN 61937-12:2010

What is this BS EN 61937-12 - Digital audio interface to convey non-linear PCM bitstreams about?  

BS EN 61937-12 discusses digital audio and interface for non-linear PCM encoded audio bitstreams lying IEC 60958 with a focus on non-linear PCM bitstreams according to the DRA formats. Sound quality makes a noticeable difference to user experience, and users seek better sound quality features in the equipment. 

BS EN 61937-12 is the 12th part of the multi-series on digital audio that specifies the method for IEC 60958 to convey non-linear PCM bitstreams encoded in accordance with the DRA formats. 

Who is BS EN 61937-12 - Digital audio interface to convey non-linear PCM bitstreams for? 

BS EN 61937-12 on the Digital audio interface to convey non-linear PCM bitstreams is useful for: 

• Manufacturers of products that provide audio output (televisions, phones) 
• Audio equipment manufactures  
• Audio programmers  
• Music producers 
• Sound technicians 
• Recording and dubbing studios  

Why should you use BS EN 61937-12 - Digital audio interface to convey non-linear PCM bitstreams?  

BS EN 61937-12 specifies the audio data bursts of DRA. Specific properties such as reference points, repetition period, the method of filling stream gaps, and decoding latency are specified for the DRA data type. The decoding latency (or delay), indicated for the DRA data type, should be used by the transmitter to schedule data bursts as necessary to establish synchronization between the video and the decoded audio. 

BS IEC 61937‑12 discusses DRA burst-info, format of DRA data-bursts, pause data-burst, audio data-bursts, DRA condition, DRA half-rate low sampling frequency condition, and DRA quarter-rate low sampling frequency condition.
