Serial digital interface (SDI) is a family of digital video interfaces first standardized by SMPTE (The Society of Motion Picture and Television Engineers) in 1989. [ 1 ] [ 2 ] For example, ITU-R BT.656 and SMPTE 259M define digital video interfaces used for broadcast -grade video.
SMPTE 292 is a digital video transmission line standard published by the Society of Motion Picture and Television Engineers (SMPTE). This technical standard is usually referred to as HD-SDI; it is part of a family of standards that define a serial digital interface based on a coaxial cable, intended to be used for transport of uncompressed digital video and audio in a television studio ...
In addition to setting the clock frequency, the main must also configure the clock polarity and phase with respect to the data. Motorola [4] [5] named these two options as CPOL and CPHA (for clock polarity and clock phase) respectively, a convention most vendors have also adopted. SPI timing diagram for both clock polarities and phases. Data ...
SDI-12 (Serial Digital Interface at 1200 baud) is an asynchronous serial communications protocol for intelligent sensors that monitor environment data. These instruments are typically low-power (12 volts), are used at remote locations, and usually communicate with a data logger or other data acquisition device.
SMPTE 424M is a standard published by SMPTE which expands upon SMPTE 259M, SMPTE 344M, and SMPTE 292M allowing for bit-rates of 2.970 Gbit/s and 2.970/1.001 Gbit/s over a single-link coaxial cable.
A Transport Stream, and thereby ASI when over coax, can carry one or multiple SD, HD or audio programs that are already compressed, as opposed to an uncompressed SD-SDI (270 Mbit/s) or HD-SDI (1.485 Gbit/s). An ASI signal can be at varying transmission speeds and is completely dependent on the user's engineering requirements.
“Anyone can decide to cut back or re-think their relationship to alcohol, regardless of quantity, frequency, or context for when they drink,” says Marilyn Piccirillo, psychologist and ...
ARINC 429 is a data transfer standard for aircraft avionics. It uses a self-clocking, self-synchronizing data bus protocol (Tx and Rx are on separate ports). The physical connection wires are twisted pairs carrying balanced differential signaling.
