Pass the Huawei HCNP-VC H11-861_V2.0 Questions and answers with ExamsMirror

Several video compression standards that are currently widely used include: H.261H.263 and H.264 and MPEG-1. MPEG-2 and MPEG-4. Its H.26X series of standards is primarily used for real-time video

communications, and the MPEG series of standards is primarily used for video storage (DVD), video broadcasting, and video streaming.

In an RTP packet, the initial value of the Sequence number is random, no RTP packet is sent, and the sequence number is incremented. The receiver detects packet loss and rebuilds packets based on it.

Network recording and broadcasting does not occupy any resources of the MCU, and there is no interference with the running status of the video conference.

RAS messages are a type of message specified in the H.225.0 protocol, which is a protocol used between nodes and gateways to perform management functions, mainly including registration, access

control, and status.

TCs are capability exchange requests that inform the peer of the capability information ( ).

The HD terminal provides remote control interface, web management, remote SSH function, and assigns a user name and password to each service.

Network recording can record the audio and video output of any venue in the video conference (voice, SD/HD/Zhizhen) and play it back on demand via web.

During point-to-point calls under different GKs, LRQ uses GK routing prefixes to query neighbor GK for information about the called node.

In the MCU's web page, the format of the exported address book information is ( ). (Fill in the blanks)

Forward Error Correction FEC enables super error correction when more than 0.1% of the media stream drops within 10S are detected after the two parties have established a call. The super error

correction function will divide the call bandwidth into a part and use it to transmit redundant code streams that are anti-packet loss.

Remote audio loopback, from audio input, encoding, transmission through the network to the remote end and then forwarded back, the main test network connection is normal.

There are ways to join an IVR meeting at a venue. (Fill in the blanks)

GK's active-standby inversion is coordinated by a heartbeat connection.

In H460 networking, the H.245 TCP connection of the private network terminal is established with TS.

H. 225 is used for media channel control, including call signaling (Q. 931), and RAS messages between nodes and GKs. ( )
