Several generic digital data connection standards are designed to carry audio/video data along with other data and power: USB was designed as a single connector to support all needs, including any generic data, audio/video, power, and more; DisplayLink is its most successful Audio+Video protocol. Until the 3.0 revision, very low data rates ...

The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
ASI has one purpose only: the transmission of an MPEG Transport Stream , [7] [8] and MPEG-TS is the only standard protocol universally used for real-time transport of broadcast audio and video media today. Even when tunneled over IP, MPEG-TS is the lowest-common-denominator of all long-distance audio and video transport.
The system was commonly used to connect data storage devices and DV (digital video) cameras, but was also popular in industrial systems for machine vision and professional audio systems. Many users preferred it over the more common USB 2.0 for its then greater effective speed and power distribution capabilities.
The figures below are simplex data rates, which may conflict with the duplex rates vendors sometimes use in promotional materials. Where two values are listed, the first value is the downstream rate and the second value is the upstream rate. The use of decimal prefixes is standard in data communications.
RFC 3551, entitled RTP Profile for Audio and Video (RTP/AVP), specifies the technical parameters of payload formats for audio and video streams. The standard also describes the process of registering new payload types with IANA; additional payload formats and payload types are defined in the following specifications:
bits 4–7: Used to indicate the format of the user channel word; Byte 2: Audio word length bits 0–2: Aux bits usage. This indicates how the aux bits (time slots 4–7) are used. Generally set to 000 2 (unused) or 001 2 (used for 24-bit audio data). bits 3–5: Word length. Specifies the sample size, relative to the 20- or 24-bit maximum.
