[1.1] The new VIVE Pro Virtual Reality stereo display uses 3 primary colors for each pixel. Assume a 24-bit number represents each of these primary colors, and the VIVE Pro resolution of each of its two screens is full HD (1920x1080 pixels). Each eye sees an image called "frame". a. How large is the buffer of the graphics hardware that can store 1 frame, in bits and in bytes? Ans. 18,662,400 bytes/frame Alternate acceptable answer is the buffer holds the frames of both eyes,thus holds 37,324,800 bytes/frame b. The new Vive Pro, unlike its predecessor, is wireless. That means no cables to the PC, and each frame is being transmitted over a wireless network. If there are 120 frames transmitted for each eye every second, what is your minimum network bandwidth that can accommodate such hardware, if all packets are received? Ans. 35,831 Gbits/second c. Now assume that 15% of bits are lost and need to be retransmitted. What minimal network bandwidth is needed in this case?
