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 standard SMPTE 349M: Transport of Alternate Source Image Formats through SMPTE 292M, specifies a means to encapsulate non-standard and lower-bitrate video formats within an HD-SDI interface. This standard allows, for example, several independent standard-definition video signals to be multiplexed onto an HD-SDI interface and transmitted ...
The Society of Motion Picture and Television Engineers (SMPTE) (/ ˈ s ɪ m p t iː /, rarely / ˈ s ʌ m p t iː /), founded in 1916 as the Society of Motion Picture Engineers or SMPE, [1] is a global professional association of engineers, technologists, and executives working in the media and entertainment industry.
Two standards, SMPTE 272M (for SD) and SMPTE 299M (for HD and 3G) define how audio is embedded into the ancillary space. The SD and HD standards provide for up to 16 channels of PCM audio, while 3G allows up to 32 channels, typically encoded in the AES3 format.
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. These bit-rates are sufficient for 1080p video at 50 or 60 frames per second. [ 1 ]
Commonly used digital SD SDI baseband signal = SMPTE 259M-C, 270 Mbit/s bitrate Commonly used Frame rate = 30 frame/s black and white, 29.97 interlaced frame/s color Black level = 7.5 IRE for NTSC , 0 IRE for NTSC-J in Japan and PAL-M in Brazil .
Hailing from Japan, these digital pets were all the craze in the ’90s. By enabling users to care for a virtual pet, the pocket-sized devices mimicked all the responsibilities of real pet ...
SMPTE ST 296 is a standard published by SMPTE which defines the 720 line high definition video formats including 720p50 and 720p60. It is frequently carried on serial digital interface physical cables defined by the SMPTE 292M standard.
