Sound quality makes a noticeable difference to user-experience, and users seek better sound quality features in the equipment. BS IEC 61937‑14 is the 14th part of the multi-series on digital audio with a focus on the interface for non-linear PCM encoded audio bitstreams. BS IEC 61937‑14 describes the method to convey non-linear PCM bit streams encoded according to the AC-4 format.
BS IEC 61937‑14 on the digital audio interface to convey non-linear is useful for:
The audio data bursts and specific properties such as reference points, repetition period, the method of filling stream gaps, and decoding latency are specified for each data type that is used by the transmitter to schedule data bursts as necessary to establish synchronization between picture and decoded audio.
BS IEC 61937‑14 specifies the AC-4 audio data-burst. The decoding latency (or delay), indicated for the data type, should be used by the transmitter to schedule data bursts as necessary to establish synchronization between picture and decoded audio.
BS IEC 61937‑14 discusses the mapping of the audio bitstream onto IEC 61937-1, the format of AC-4 data-bursts, pause data-burst, audio data-burst, the latency of the AC-4 decoder, the latency of the AC-4 HBR4 decoder, the latency of the AC-4 HBR16 decoder, and latency of the AC-4 LD decoder. With obedience and compliance to BS IEC 61937‑14, you can achieve precision in terms of product functionality.
