Each video communication service provider has its own High-definition conference room system. However, among the many service providers, only UT can achieve 720p HD video effect at 60 frame/sec rate. Utroom is designed to integrate IP networks and can decode and display multiple high-definition video sources in a much higher quality video system than dedicated bandwidth. The

Utroom system features easy to use, easy to configure, and can be activated through multiple-screen voice. Based on flexible meeting control options, users can easily manage the system through utportal or other remote control devices. To ensure that the user's normal working state can be rendered remotely with more natural effects, utroom can also seamlessly interoperate with utdesktop clients, allowing all users to join the meeting anytime, anywhere.

(3) Utdesktop: High quality meetings anytime, anywhere

by fusing IP networks, UT can extend high quality video conferencing to ordinary desktop PCs! This "high quality", far beyond the user experience of the vast majority of conference room video conferencing system. The

Utdesktop is a software client that can be easily used and managed by Utportal to send and receive high-definition quality video bit streams. Each user will be given a password-protected personal space so that they can hold a meeting at any time, either immediately or in advance. In addition, the no scheduled Instant conferencing feature for video conferencing can also be used for voice conferencing and networking meetings. Whether you're in a dedicated video conference room or sitting in your own utdesktop, a user needs a USB camera, a microphone, and a computer to make multiple video calls to others.

(4) Utgateway: Consolidate and reuse legacy systems

UT the company realizes that it is impossible for companies to abandon all legacy systems when investing in new videoconferencing systems. To this end, UT Utgateway carefully launched to help users easily to the legacy of the PO litong (Polycom), Ted (Tandberg) or other multi-point control unit system integrated into the new H.264/SVC system, seamless interoperability. The

Utgateway supports H.323 and SIP standards, and can support h.254 and h.263 outside of h.239 data collaboration in video and broadband audio. Video conferencing participants can still see clear images and smooth movements, even when conditions are extremely bad.

(5) Utrouter: A major breakthrough in the field of video communications

as the core of UT's HD video conferencing system, Utrouter completely subverts the traditional video technology architecture of the past decades. InUT in the conference system, all the solution codes are at the endpoint, intelligent Utrouter can handle packet exchange with the best efficiency, neither affect the video quality, nor lead to obvious delay.

Because of the restrictive impact of factors such as bandwidth, processing power, screen resolution, and so on, utrouter can efficiently transfer the number of packets with the maximum processing power of the endpoint, thereby greatly increasing the utilization of the network. While processing power and bandwidth are constantly changing, utrouter is able to continuously test and calibrate the amount of packets that are appropriate for transmission to ensure that each endpoint gets the best quality video. Even if the local environment is fickle, utrouter can still maintain good reception capability. Each router supports up to 100 high-definition video ports, as well as numerous virtual conference rooms, and is managed with a unified utportal that greatly reduces the cost of redundancy and geographic distribution.
