Hence, the number of cameras needed to capture vivid details such as facial features or license plate is largely reduced. These systems can be directly upgraded from analog to HD-SDI; therefore, installers can simply replace front-end products. This is because when integrating SDI and IP systems, the front-end HD-SDI real-time video streams are captured into a video encoder, then the converted digital signals are distributed to a video matrix switcher for real-time monitoring.

The signals are then further sent to an encoder for storing. This approach ensures HD rendition in monitoring and storing. While bad connections or false linkage of connectors in analog systems simply cause horizontal strips or jitters on the video, HD-SDI camera installations, on the other hand, cannot stand any false connections because the video will be lost.

Analog video signal frequency is in waveforms whereas HD-SDI signal frequency looks like serrated edges. Transmission Currently, HD-SDI supports a limited transmission distance of meters on regular video coaxial cables. Distance larger than meters can result in less stable transmission. For a longer distance, installers are suggested to use fiber optic to ensure video quality and reliability. The proven and tested distance limitation is 20 meters, but video signals would be weakened after 15 meters on HDMI.

In some occasions that require long-distance transmission, such as the connection of two distant studios, copper is a bit powerless, and at this moment, the optical fiber cable becomes a natural substitute for copper. Only single-mode optical fibers and corresponding optical connectors are allowed when transmitting high-definition signals — Electrical, electrical-optical conversion by the appropriate optical receiver and optical transmitter to complete.

Taking into account the distribution of high-frequency transmission cable parameters affects the transmission of high-definition video signals, the cable length will be greatly reduced. The data transmission format of HD-SDI is basically the same as the transmission format of SD-SDI, and the luminance signal Y and the color difference signals Cb and Cr subjected to time-division multiplexing are handled as bit words. Each bit word corresponds to a color difference sample and a luminance sample.

With the advent of high definition HD video standards such as i and P, interfaces have been adapted to handle higher 1. Dear sir Can u tell me i am using sony nx5r camera i need to make Meter cable what is the cable i can use. You must be logged in to post a comment.
