NEW QUESTION # 25
Which of the following statements is true about image sampling?
- A. The transmission rate of video data using YUV 4:2:0 is 140 Mbit/s. If the 4:2:2 mode is used, the transmission rate required by the video is 175 Mbit/s.
- B. The YUV 4:2:0 sampling mode is half the size of the YUV 4:4:4 sampling mode.
- C. For human eyes, the Y component in YUV is the most important. Therefore, downsampling can be performed on the UV components.
- D. RGB components have weak correlation, which is unfavorable for video image compression. Therefore, RGB is often used for image display.
Answer: B
Explanation:
YUV 4:2:0 subsamples chroma by a factor of two in both horizontal and vertical dimensions, reducing total data to half of the full-resolution YUV 4:4:4 format.

NEW QUESTION # 31
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.)
- A. 225 RAS messages (registration, admission, status) always traverse the SC (gatekeeper) for endpoints in the same zone.
- B. In this process, the H.225 call signaling interaction between T1 and T2 must pass through the SC.
- C. In this process, the H.225 RAS signaling interaction between T1 and T2 must pass through the SC.
- D. In this process, the media stream must be directly transmitted between T1 and T2.
- E. Endpoint control signaling involved in this process mainly includes H.225 RAS, H.225 Call Signaling, and H.245.
Answer: C,D,E
Explanation:
RTP media is exchanged directly between T1 and T2 once the call is established.
The call control sequence involves H.225 RAS (registration/admission), H.225 call signaling (SETUP/CONNECT), and H.245 control for capabilities.

NEW QUESTION # 35
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?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: C
Explanation:
Dual-channel PCM at 8 kHz with 8 bits per sample yields 8,000 × 8 = 64 kbit/s per channel; two channels give 64 × 2 = 128 kbit/s.

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.)
Answer:
Explanation:
2986
Explanation:
Uncompressed 1080p at 60 fps has 1920 × 1080 = 2,073,600 pixels per frame. At 24 bits per pixel, that's 2,073,600 × 24 = 49,766,400 bits per frame. Multiplied by 60 fps gives 2,985,984,000 bit/s, which is approximately 2986 Mbit/s.
