1 Video Encoding with Multicore Processors March 29, 2007

2 Video is Ubiquitous... Demand for Any Content Any Time Any Where Resolution ranges from 128x96 pixels for mobile to 1920x1080 pixels for full HD Frame rates range from 10 to 60 fps The only constant is that raw digital data always outstrips available capacity! FORMAT lpf ppl bpp Mbpf fps Mbps 2 hr video Channel Mbps Storage GB Sub-QCIF MB GSM.0014 POTS.0056 Brdbd.3840 NTSC GB Satellite 006 Cable 020 DVD 17 ipod 80 HDTV , TB T OC HD-DVD 30 Blu-Ray 50 2

3 High Definition = High Quality 1080 lines per frame 60 frames per second Frame 16 x 9 aspect ratio pixels per line Le Grand Jatte (aka Sunday in the Park ), 1886 George Seurat 120 x 81 inches About 3.5 million dots = 19 dpi view from feet (vs. about 2.1 million pixels on HDTV screen) 24 bits per pixel RGB/YUV 3
