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 ...
The various serial digital interface standards all use (one or more) coaxial cables with BNC connectors, with a nominal impedance of 75 ohms. This is the same type of cable used in analog composite video setups, which potentially makes for easier "drop in" equipment upgrades (though may be necessary for long runs at the higher bitrates for older oxidising or lower grade of cable to replaced ...
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.
An integrated receiver/decoder (IRD) is an electronic device used to pick up a radio-frequency signal and convert digital information transmitted in it. Consumer IRDs [ edit ]
An oscilloscope trace of a tri-level sync pulse. Tri-level sync is an analogue video synchronization pulse primarily used for the locking of high-definition video signals ().
Level B-DL format is the mapping of dual-link HD-SDI/SMPTE 372M (i.e.: 1080p up to 60 fps) in a single serial digital interface at the nominal 3 Gbit/s. That is, one video signal, two streams, in one cable.

Crystal oscillators can be manufactured for oscillation over a wide range of frequencies, from a few kilohertz up to several hundred megahertz.Many applications call for a crystal oscillator frequency conveniently related to some other desired frequency, so hundreds of standard crystal frequencies are made in large quantities and stocked by electronics distributors.
