BS EN 61937-8 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 Windows Media Audio (WMA) Professional format. Sound quality makes a noticeable difference to user experience, and users seek better sound quality features in the equipment.
BS EN 61937-8 is the eighth part of the multi-series on digital audio that specifies the method for the digital audio interface specified in IEC 60958 to convey non-linear PCM bitstreams encoded in accordance with the WMA Professional format.
BS EN 61937-8 on the digital audio interface to convey non-linear is useful for:
BS EN 61937-8 specifies the audio data-burst for WMA Professional. Specific properties such as reference points, repetition period, the method of filling stream gaps, and decoding latency are specified for each data-type. The decoding latency (or delay), indicated for the data-types, should be used by the transmitter to schedule data-bursts as necessary to establish synchronization between picture and decoded audio.
BS IEC 61937‑8 discusses the mapping of the audio bitstream ontos IEC 61937, Windows Media Audio Professional burst-info, the format of WMA Professional data-burst, Pause data-burst, and audio data-bursts. This will help the digital audio interface to convey non-linear PCM bitstreams encoded with the WMA Professional format.
