RTCP can ensure the transmission quality well through RR, and each participant who receives data must send a RR.
The color rendering index affects the reproducibility of the image, and when the color rendering index is low, the color of the image will deviate greatly from the original image. ( )
A multi-screen conference needs to occupy the MCU one-way multi-screen encoding resources, and N sprites need N/2 multi-screen decoding resources.
The ARQ carries information about the node itself (IP address and port number), as well as information about the hard-called terminal (terminal number) and ( )
Omnidirectional poetry is suitable for large conference rooms, and pointing pickup is suitable for small conference rooms.
Dialogs can be divided into INVITE transactions and non-INVITE transactions, where the INVITE transaction in turn includes a request message and a response message.
In MCU ride-on-the-wall mode, you can configure IP routing to send and receive data through GE1.
Illuminance is based on the luminous flux received by the vertical surface as the standard, and if oblique illumination is used, the illuminance decreases. ( )
A transaction can only be identified by a unique branch.
Diagnosis of peer-to-peer networks without networking traversed by public and private networks. ( )
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.
GK can only be installed on the C or D drive of the operating system.
VR can be understood as an interactive way to guide users to a destination meeting or create a meeting. ( )
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.
Background lighting can improve monotonous backgrounds; The background light should be dimmer than the main light to highlight the human image and create a sense of depth. ( )
