QuestionQ1

Audiovisual technologies

At present, widely used video-compression standards include H.263, H.264, H.265, MPEG-1, MPEG-2, and MPEG-4. The H.26X series standards are primarily used for real-time video communication, while the MPEG series standards are primarily used for video storage (DVD), video broadcast, and streaming media.

Explanation

H.264 and H.265 are jointly aligned ITU-T/ISO video-coding standards intended for videoconferencing and communication as well as digital storage media, television broadcasting, and Internet streaming. The H.26x and MPEG labels therefore do not create the stated application split.

QuestionQ2

Audiovisual technologies

Which of the following statements is correct regarding image sampling?

Choose two
Explanation

YUV 4:2:0 retains full-resolution luma while sampling each chroma component at one-quarter resolution, so it uses half the component-sample data of YUV 4:4:4. Because human vision is more sensitive to luminance detail than chrominance detail, the U and V components can be downsampled.

QuestionQ3

Session Initiation Protocol (SIP)

Which of the following header fields indicates the route of a response message?

Explanation

In SIP, each server adds a Via header field while forwarding a request. Responses use the Via header fields to return along that request path.

QuestionQ5

Audiovisual technologies

Assume a dual-channel audio file uses PCM encoding, has an 8 kHz sampling frequency, and represents each quantized sample value with an 8-bit binary code. What is the audio file’s encoding rate, in kbit/s?

Explanation

For PCM audio, the encoding rate is the sampling frequency times the bit depth times the number of channels. With 8 kHz sampling, 8 bits per sample, and two channels, the rate is 8,000 × 8 × 2 = 128,000 bit/s, or 128 kbit/s.
