(a) A video sequence with 4:2:0 chroma subsampling and 8 bits per pixel is encoded using MPEG-2 video encoder. It has a frame resolution of 720x576, a frame rate of 30 fps, and a video length of 110 minutes. The following settings are used to generate the compression bitstream: on average, 1 I-frames, 4 P-frames and 10 B frames are encoded per Group of Picture (GOP). The video is compressed at the required quality has an I-frame average compression ratio of 10:1, an average P- frame compression ratio of 30:1, and an average B-frame compression ratio of 70:1 Assume that the compression ratio includes all necessary headers, calculate the encoded video size. State your assumptions, if any (10 Marks) (b) 3D video can be represented using stereoscopic format for the left view and right view of the scene (i) With the help of simple diagrams, explain simulcast coding for encoding of (ii) What is the main disadvantage of simulcast coding in terms of coding stereoscopic 3D video efficiency? Owing to this main disadvantage, what is the major application of simulcast coding? (iii) With the help of simple diagrams, explain inter-view prediction coding for encoding of stereoscopic 3D video (a) A video sequence with 4:2:0 chroma subsampling and 8 bits per pixel is encoded using MPEG-2 video encoder.
