Assume that a dual-channel audio file uses the PCM encoding, the sampling frequency is 8 kHz, and each quantized sample value corresponds to an 8-bit binary code. What is the encoding rate (kbit/s) of the audio file?
SIP and SDP are independent of each other. SIP can implement multimedia calls independently to add new applications or media easily.
The main functions of H.245 include capability negotiation, video encoding, and master-slave determination.
Which of the following statements are true about the intranet-only SC cluster network? (Choose all that apply.)
In the encrypted conference scenario, the SIP transmission type must be set to TLS on both the MCU and endpoint.
At an SMC video conferencing system site, the customer wants to deploy a conferencing system with converged firewall ports, with a planned DMZ. The SC1 is deployed on the intranet and SC2 is deployed in the DMZ. In this case, which of the following deployment modes is the most suitable one for SC1 and SC2?
FILL BLANK
In a SIP-only multipoint conference, when a participant sends the presentation, the system uses the ____________ protocol for presentation. (Enter the abbreviation.)
The Call priority protocol on the Box 310 endpoint is set to SIP by default.
Which of the following statements is false about point-to-point calls?
In an SVC hybrid conference (scheduled on the SFU and IAU), when an AVC participant views continuous presence of an SVC participant, dynamic codec resources on the IAU are consumed. When an AVC participant views continuous presence of other AVC participants, no dynamic codec resources are consumed.
By default, the SMC provides six user roles. Default permissions of each user role can be modified or deleted based on site requirements.
An endpoint is disconnected from a conference due to a power failure. After the endpoint is powered on again, it is not called to the conference again, and the SMC does not detect that the endpoint is disconnected. The SMC O&M engineer finds that this fault is caused by the “Timeout for hang-up upon no code streams” parameter on the CloudMCU. Which of the following parameter values may cause this fault? (Choose all that apply.)
During a point-to-point call between different GKs, the local GK sends an LRQ request to the neighboring GK to query the information about the called node.
Which of the following information is displayed when you run the CloudMCU debugging command “mswt-media allflow”?
The VDC can be used with the Huawei video conferencing platform to provide rich conference control functions. Conference control settings can be customized, and conference control shortcut keys and descriptions can be set.
Assume endpoints T1 and T2 are registered with the same SC node zone (signaling routing is enabled on the SC). After T1 calls the number of T2 using H.323, T1 communicates with T2. How many TCP connections are established in this process?
Which of the following statements are true about the SC cluster reconstruction deployment scenario? (Choose all that apply.)
An AVC conference is scheduled on the CloudMCU (working in SFU mode) and VP9850 (working in IAU mode). After the conf get strmInfo 41353221 command is executed on the CloudMCU, the following information is displayed:
Which of the following is the video stream number generated after the IAU decodes and re-encodes the three video streams of Site (16), Site (17), and Site (18)?
