System of high-definition video conference aids informatization of fire control

From;  Author:Stand originally

The system backs up - MCU advocate accuse board, business board, main chip all can achieve millisecond level automatic rearrange, the conference when rearrange is completely insusceptible. Terminal has double net opening, can join at the same time two pieces of different networks, realize port backup.

Circuit backs up - do not stabilize character according to H.323 network, the conference terminal of this system and MCU still should have IP network to get used to ability oneself at the same time, implementation Qos ensures a mechanism. When network occurrence congest, terminal meeting is first those who make sure frequency flows send, make sure the conference is uninterrupted thereby.

Advanced sex

The core that this system builds inspects bandwidth of frequency, network to take up to use high-definition clear function of low, error correction is strong, stable reliable product. Video communication agreement adopts advanced H.323 agreement platform, satisfy the bandwidth requirement of wide area newwork already, the confluence application of the system such as compatible speech, monitoring.

Video encode technology - use the current and advanced video that applies to a variety of bandwidth conditions to fall to compress algorithmic H.264720P.

Frequency encode technology - use the AAC of advanced dual track, high compression ratio, broadband speech technology that can achieve CD level acoustic quality - LD.

Data encode technology- - the transmission definition that data sheds can amount to SXGA(1280 × 1024) , implementation high definition draws the data of acoustic quality of qualitative, high fidelity and tall clarity to show, assure the high quality of video conference adequately.

True implementation video, frequency, data " three-dimensional an organic whole " high-definition solution.

Use a sex easily

The conference controls a function - the system can choose a variety of conferences to hold mode, the administrative software that the administrator can handle major undertakes booking to the conference, hold, the operation such as the end. Personnel attending the meeting can control terminal to have the operation such as initiate, speech, hang up through the remote controller.

Graphical interface function - the station of graphical interface management that the system should use major undertakes administrative to whole system, supervisory equipment reachs the situation of the network.

Classification the function that distribute right - systematic node is much, group network is intricate, 2 class net and the means that 3 class net communication use MCU cascade come true, each class MCU must have corresponding administrator to undertake maintenance. Because this asks the system should be had,classification the function of minute of authority, to attributive of set of all management user.

Security

The system manages equipment to have strict safe safeguard to MCU, terminal unit and relevant network, support password attestation. Can install on MCU and terminal open, shut control port. Supportive H.235 increases secret agreement, offer a letter to make, media shedding is added close, prevent an user to be risked by copy; Protective conference information is not intercepted and capture to translate in deferent process, prevent divulge a secret.
