4. Audio codec protocol, at least support G.711, G.722, G.722.1*, G.722.1C*, AAC-LD, SILK and other audio compression algorithms, support automatic lip synchronization, echo cancellation and VAD speech excitation detection technology.
5. Support ITU-T H.323, IETF SIP multimedia framework protocol;
6. Support ITU-T H.239, BFCP dual-stream protocol;
7. Audio input interface, at least 1 route input, at least 1 microphone input;
8. Audio output interface, at least 1 route output, at least 1 HDMI audio output;
9. Video input interface, at least 1 x HDMI input, 1 DVI input;
10. Video output interface, at least 2 HDMI output;
11.USB port, at least 2 USB inputs;
12.NAT/ firewall traversal, support H.460.18/19, H.460.23/24;
13. Support at least dual 1080p 30 frame/second video, main video and auxiliary video dual 1080P resolution, the two channels of the double stream image frame rate is not less than 30 frames per second.
14.H323 media security, at least support H235.6 (AES-256), H235.6 (AES-128), SRTP (AES-128&SHA1-80);
15.SIP media security, at least SRTP (AES-128&SHA1-80);
16.★ Support at least 64kbps to 8Mbps call bandwidth.
17. Support the local and remote view function, that is, the local video output video screen to the remote synchronous output, local and remote watch the same video screen;
18.★ Support the built-in MCU function of the conference terminal, and support at least 1+3 meetings through the built-in MCU;
19.★ Support video conference terminal local USB recording, what you see is recorded, you can choose to record local picture, remote picture, double stream picture and multi-picture, generate standard mp4 format files, terminal on demand;
20. Support timing automatic switch function;
21.★ Support analog microphone, USB microphone input;
22. Supports quick import and export of terminal address books;
23.SIP signaling security, at least support TLS for SIP call signaling encryption protection;
24. Support the terminal to directly RTMP to the live broadcast platform, live broadcast of the meeting;
25. Support RTP transmission protection, without manual intervention, the terminal can automatically analyze, automatically identify and protect the RTP code stream, and self-check and restore the abnormal code stream. When the network packet loss is serious, the system automatically detects the packet loss delay and implements QOS-FEC protection. The system is not affected by packet loss within 25%.
