S/PDIF is an audio-only format carried over electrical coaxial cable (with RCA jacks) or optical fibre . Note that there are no differences in the signals transmitted over optical or coaxial S/PDIF connectors—both carry exactly the same information. Selection of one over the other rests mainly on the availability of appropriate connectors on ...
S/PDIF is a data link layer protocol as well as a set of physical layer specifications for carrying digital audio signals over either optical or electrical cable. The name stands for Sony/Philips Digital Interconnect Format but is also known as Sony/Philips Digital Interface. Sony and Philips were the primary designers of S/PDIF. S/PDIF is ...
TOSLINK (Toshiba Link) [3] is a standardized [4] optical fiber connector system. [5] Generically known as optical audio, the most common use of the TOSLINK optical fiber connector is in consumer audio equipment in which the digital optical socket carries (transmits) a stream of digital audio signals from audio equipment (CD player, DVD player, Digital Audio Tape recorder, computer, video game ...
The precursor of the IEC 60958 Type II specification was the Sony/Philips Digital Interface, or S/PDIF. Both were based on the original AES/EBU work. S/PDIF and AES3 are interchangeable at the protocol level, but at the physical level, they specify different electrical signalling levels and impedances, which may be significant in some applications.
The most commonly used professional interface is AES3, developed by the Audio Engineering Society and the European Broadcasting Union, which transmits two channels of digital audio up to 24-bits 192 kHz over a balanced XLR cable. S/PDIF (Sony/Philips Digital Interface) is the consumer version of this protocol, which uses either RCA leads or ...
The communication functionality is provided by driver software known as MOST Network Services. MOST Network Services include Basic Layer System Services (layers 3, 4, 5) and Application Socket Services (layer 6). They process the MOST protocol between a MOST network interface controller (NIC) and the API.
When the sound card uses a custom driver for use with the system supplied port class driver PortCls.sys or implements a mini-driver for use with the streaming class driver, applications can bypass the KMixer completely and use the kernel streaming interfaces instead to directly interact with audio driver and reduce latency. Windows 98 includes ...
MADI uses 75-ohm coaxial cable with BNC connectors or optical fibre to carry up to 64 channels of digital audio in a point-to-point connection. It is most similar in design to AES3, which can carry only two channels.
