What is high-profile – Troubleinthepeace


The birth of High Profile created a whole new step in real-time video and created a big change in the media image market.

You are viewing: What is High-profile?

While H.264 is a widely established and deployed standard for video compression, the much simpler and less efficient Baseline Profile is still being used for visual communication applications today.

What is H.264? What makes High Profile H.264 different from other H.264? What impact will High Profile have on the visual media market? How will customers benefit from it? How will this technology help CIOs roll out video across the organization? How does High Profile interact with other video functionality?

This article will look at High Profile from both business and technology perspectives, and provide answers to these questions.

Impact of HD on the HNTH market

High Definition (HD) video leads to a rapid and overall change to the video conferencing market in particular and visual communication in general. The new generation of video systems offers sharp images and high frame rates that make real-time video look like a produced movie, far from the low-quality video users of previous generations. . New applications emerge, most notably immersive telepresence that combines HD video and audio technology with multiple screens and room designs optimized for immersive interaction. By 2008, most enterprise video equipment operated with HD support. The only limitation is the higher bandwidth required to compress HD video images. This puts additional scalability requirements on video network infrastructure, resulting in a complete new scalable, redundant, and reliable solution, as described in “Scaleable Architecture for Video Delivery. ”

But while high-end telepresence systems and selected conference rooms can connect to HD quality via dedicated virtual LANs, and well-designed MPLS WANs, most regular users aren’t. access up to HD even if they already have a system that supports HD. Very few organizations have the network resources to allow HD video to flow freely. Cuts from the 2008-2009 financial crisis did not allow most CIOs to upgrade their networks, restricting HD to premium users, venues, or festivals.

Where HD has been widely deployed, users will quickly discover the benefits of high-quality picture and sound. HD video has become a viable alternative when traveling and face-to-face meetings. HD makes visual communication much more attractive, and mass deployment is in demand regardless of the type and size of the organization. The problems of CIOs today are how to meet user needs and requests for HD communications while not breaking the bank for network upgrades.

Now that HD-enabled systems and infrastructure are scalable enough to support large HD deployments, bandwidth is the ultimate limiting factor for HD-quality HNTH deployment.

Advances in video compression technology.

The ITU-T H26x series of standards are established standards for interoperability. The original H.261 standard has been replaced by H.263 and the latest H.264. The standards describe how to compress video so that it can be efficiently transmitted over the network, and how to decompress at the receiver.

A native HD video that could require up to 1 gigabit per second (1Gbs) of bandwidth is clearly not suitable for any network. By applying H.264 Baseline Profile, 1Gbs can be compressed down to 1Mbs, which is 1000 times, which is an impressive technical achievement. However, if using H.264 High Profile, the videos can be compressed down to 512kbs, which is 2000 times.

High Profile significantly reduces a key barrier to entry for visual communications, enabling wider deployment across organizations. CIOs concerned that adding video or integrating video into their UC application could overwhelm their IP networks now that have the option to roll out videos without redesigning their entire network.

Currently, this technology is being applied by Yealink in the production of its video conferencing equipment such as VC110, Vc120 to VC400. See Yealink’s products at: yealink.com.vn
