What Is SDI And SDI Camera. In this article, you will read the history of SDI, what is SDI cable, what is SDI Camera, uses of SDI camera, various types of SDI cables, pros of SDI cable, cons of SDI cable, and difference between SDI and HDMI.
History Of SDI:
SDI cable is used to stream on televisions since the 1990s. A coaxial cable is used with one end of the cable attached to another end. Audio and video transmission of the latest cable released in 2015 is 270 megabits/sec up to 12 gigabits/sec.
It is one of the professional video transmission methods. SDI cable is preferably used over other methods because of its durability, reliability and its range which is up to 300 ft.
What Is SDI And SDI Camera
What is SDI cable?
SDI stands for Serial Digital Interface. SDI cable is a broadcasting coaxial cable. It is used to connect televisions, cameras, and other video sources to encoders, switchers, and other production systems.
What Is SDI Camera?
A camera which supports SDI video output is known as an SDI camera. SDI cable can be connected to different video equipment like a recorder, a production system, or a streaming encoder with the help of the locking connector. This connection can be used to output video from SDI cameras.
In the 90s, people used SDI cameras for streaming video by connecting the streaming device with the recorders.
Uses Of SDI Camera:
The uses and features of SDI cameras are as follows:
-SDI cameras are high-definition cameras.
-SDI cameras are used for professional work or production.
-It can easily toggle between recording and broadcasting live shows.
-It delivers the best video from different angles and frames.
-SDI cameras can be used in CCTV video solutions and monitoring applications.
-SDI cameras are a good option for Wi-Fi or IP cameras.
Various Types Of SDI Cables:
There are two types of SDI cables i.e. Plenum and Non plenum.
Plenum cables are used in the ceilings and walls. They are best for long-distance and permanent installation. They are fire resistant, which provides better safety and durability.
Non-plenum cables are less expensive and cannot withstand fire. If the wires get burnt, they release harmful gases.
There are different types of SDI cables available in the market. Here are some of the types and their output formats.
Pros Of SDI Cables:
-More stable in connection.
-Made up of a single strand of wire which acts as a serial data pipeline.
-BNC connectors keep the cable in place.
Cons Of SDI Cables:
-Heavier than fibre.
-Expensive than others.
Differences Between SDI And HDMI:
-SDI transmits raw data.
-HDMI transmits processed image data.
-SDI is the main source of supply for long distances.
-HDMI cable needs extension support after 50 feet.
-In SDI, the data is first analyzed and encoded in the Atomos recorder to show the image on the screen.
-In HDMI, the image data is transferred directly, as it is formed in the camera.
