What is HD-SDI used for?
What is HD-SDI used for?
HD-SDI is a high-definition digital component serial interface. HD-SDI is high-definition radio and television camera which is real-time and uncompressed. It is another scientific and technological progress in the security monitoring field. It provides a high-definition image source for the monitoring center.
What is HD-SDI cable?
SDI – Serial Digital Interface. SDI is a professional digital video standard developed for broadcast video. SDI carries uncompressed digital video and 16 channels of PCM audio. SDI is transmitted over 75 Ohm coax cable with BNC connectors, typically RG-6. HD-SDI and above can be run up to 300′.
Does HD-SDI carry audio?
SDI is simple and is a pipeline of pixels pouring down the cable at high speed! SDI includes video, audio, timecode and metadata all embedded in a single cable. Because of its reliability, SDI is ideal for live production, post and broadcast.
What is the difference between SDI and HD-SDI?
SD-SDI: The SD-SDI standard support the 270 Mb/s bit rate. HD-SDI: The standard known as the HD Serial Digital Interface (HD-SDI) is standardized in SMPTE 292M; Although this standard is known as the 1.5 Gb / s interface, the bit rates supported by HD-SDI are actually 1.485 Gb / s and 1.485 / 1.001 Gb/s.
What is difference between SDI and HDMI?
SDI and HDMI both support uncompressed digital video transmission, but the HDMI interface to use the 19-line transmission, SDI with the ordinary 75-ohm coaxial line can. HDMI can only transmit the longest 40 meters, SDI can transmit 120-400 meters.
How is audio embedded in SDI?
When we talk about embedded audio in a SDI video signal, we refer to the digital audio that is included in the frame of the SDI digital video signal. That is, through a single cable or fiber, a video signal plus the audio signal associated with that video is transmitted.
