The virtual conference ID range of the SMC video conferencing system is set to 9100000 to 9299999. Which of the following may be the ID of a new common conference (that is not bound to a VMR)? (Choose all that apply.)
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 information is displayed when you run the CloudMCU debugging command “mswt-media allflow”?
The new and old MCU architectures differ in bandwidth and codec resource usage during cascading. The new architecture supports multiple working modes, such as MCU, SFU, and IAU. The old architecture does not provide different working modes of the MCU. Which of the following statements is false about MCU cascading?
Which of the following header fields is used to indicate the route of a response message?
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?
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)?
Assume endpoints T1 and T2 are registered with the same SC node zone. After T1 calls the number of T2 using H.323, T1 and T2 communicate with each other. Which of the following statements are true about the call process? (Choose all that apply.)
Which of the following MCU debugging commands is used to display detailed information about a specified conference?
In the non-DMZ public-private network traversal scenario (small- and medium-sized network where the SMC and SC are co-deployed), you need to configure the LAN2 port of the SC as the default routing port.
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.)
FILL BLANK
The stream transmission speed of a digitalized 1080p 60 fps analog TV signal is around ____________ Mbit/s. (Assume that a pixel is 24-bit and enter an integer.)
