5 Video Compression 20 Points A Hd 1080p Digital Movie Video Format At 24 Fps Plays Is Encoded To Deliver At Cbr Eac 1 (135.84 KiB) Viewed 34 times

5) Video Compression – 20 points A HD 1080p digital movie video format at 24 fps plays is encoded to deliver at CBR. Each pixel on average is encoded using YUV 4:2:0 representation. To achieve CBR better, the frames are organized as in GOPs with these two parameters defined as follows: Pbetween) = 7 and BbetweenP = 2. The delivery needs to be on a network supporting 5Mbits per second If delivered without compression, how many bits are required for each GOP? (6 points) This is obviously greater than what the network can guarantee. Compute the compression needed per GOP 10 support CBR on the network? (2 points) When compressing the video, assume that the compression algorithm on average compresses every P frame to about 20% of I frame and every B frame to about 70% of a P frame. What is the minimal compression ratio needed per I frame for CBR? (8 points) Though this design would work, network jitter (changes in latency/delay) is always a problem because this causes fluctuations in available bandwidth. How would you adjust this setup to better address such fluctuations? (4 points) . .
