The H460 protocol specifies that the H.323 media streaming portion of the public-private network traversal processing process is

MsDA is the master-slave decision response message, which carries the Master or Slave flag, which refers to the state of the local side.

In video conference rooms, the illuminance cannot be too low because whether it is a CCD or CMOS, the camera will have a lot of snowflake noise in low light.

H.323 is used to provide multimedia services in packet-switched networks. ( )

Fe and GEO, GE1 IP addresses can not be in the same network segment, otherwise it will cause network failure, at this time the front panel ALM light is always on. ( )

SIP messages are encoded as text.

Image format refers to the size or resolution size of the image, common image formats include, SOCIF, QCIF, CIF, ACIF, 16CIF, HD, Full HD. ( )

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

The role of the LAN2 port of the HD terminal ().

Master-slave decisions are mainly used to prevent both parties from triggering the same unsharable event or resource at the same time during communication, so a master party needs to be identified in

advance. When a conflict occurs, the slave shall act at the discretion of the master.

Mixing is actually mixing the loudest venues except for your own venue, not mixing all the venue sounds.

RTP is a real-time transmission control protocol: on a network service of multicast (multicast) or unicast (unicast). Provides end-to-end network transmission capabilities for applications to transmit real-time

data such as audio, video or simulation data.

The color temperature is defined by the absolute black body, the radiation of the light source in the visible region and the radiation of the absolute black body are exactly the same, at this time the Kelvin

temperature of the black body is called the color temperature of this light source. ( )

The secondary stream can only be displayed on one display with the mainstream, not independently.

On the terminal web page, you can set parameters for subtitles, which include banners, middle captions, and instant messages. Banners and middle captions can be displayed separately or at the same

time; Instant messages can be sent to peer-to-peer private chat, broadcast and sent, or sent at a designated venue.

H.323 gateway refers to a node that provides real-time two-way traffic between the H.323 terminal on the SCN and other nodes on the PBN.

The basic concept of white balance technology is that "white objects can be reduced to white regardless of any light source", which is a case for color casts that occur when shooting under a specific light

source Compensation is made by reinforcing the corresponding complementary colors. ( )

A single value in the header field can only appear once in the message, such as Via, Route, etc. ( )

The core of the NAT mapping is to modify the packet header (source address) to translate the source address into a NAT address ( ).

In logical SIP entities, UAS is used to initiate SIP requests and UAC is used to return SIP responses.

The Call-ID header field serves as a unique identifier for a collection of messages, and in a conversation, the Call-id must be the same in all the last requests sent by each UA. ( )

Only one P frame is sent at the beginning of the build during the call, and the subsequent video images are encoded using I frames.

TCSA refers to the capability exchange success response, which is used to return to the local side after the ability exchange is successful.

Color temperature represents the most general indicator of the spectral quality of a light source in lux (Lux , lx ). ( )

Huawei's video product fault location method can be mainly summarized as, grain and grass first, follow the vine to touch the melon, step by step, bold and careful, and pass on the torch. ( )

The chamber sound reaches a stable state during reverberation time, and the residual sound is repeatedly absorbed by the sound absorbing material in the room after the sound stops, and the original value

of the average sound energy density word decays to one part in a million (Acoustic code attenuation 60dB). The time required, expressed in T60.

Static NAT converts a private address into an Internet address, and it is many-to-many, and there is no guarantee that a private address will be converted to a public address.

Desktop tones can be taken as skin color adjacent to color or gray, avoiding the same color of skin tone; Desktop reflectance should be higher than skin tone, highlighting the skin image.

Stretch mode is stretched to a full screen proportional to the output, which captures part of the image. ( )
