Instead, it employs a combination of a gamma curve for the brightness of SDR content and a logarithmic curve for higher levels of brightness when using an HDR display. They developed the software for Windows in 1994. It has a dynamic range of at least 13 stops, much higher than SDR video.
High dynamic range (HDR) video addresses these issues. In order for this data to be transferred over a normal network -- instead of requiring a network with massive bandwidth -- codecs must be used to compress the data into digital packets, allowing the captured AV input to travel faster over broadband or Wi-Fi Internet.
Choosing the right UC product depends a lot on its features. Video conferencing is a rapidly growing technology as it helps businesses in cost reduction, faster client interaction, conducting and joining video conferences from anywhere anytime etc. But it is equally important to know when another tool will increase your ability and efficiency.
