Video Data Rate for HEW

This presentation by Huai-Rong Shao and colleagues from Samsung explores how to calculate the data rate for uncompressed video, incorporating factors like frame width, height, bits per pixel, and frame rate. It also provides insights into estimating the data rate for compressed video, highlighting the significant differences between pre-stored video formats such as JPEG and HDTV versus real-time video applications. The importance of compression techniques like MPEG, H.264, and HEVC is discussed alongside their implications for data rates and latency in various applications.

  1. Video Data Rate for HEW Date:2013-07-16 Authors: Huai-Rong Shao, et al. (Samsung)

  2. This presentation explains • How to calculate the data rate of uncompressed video • How to estimate the data rate of compressed video Motivation Huai-Rong Shao, et al. (Samsung)

  3. (Uncompressed video data rate) = (Video frame Width)*(Video frame Height)*(Bits per pixel)*(Video frames per second) (Bits per pixel) depends on the (Bit depth per each color element) and video format (4:4:4, 4:2:2 or 4:2:0) Data Rate of Uncompressed Video Note: Traditionally commercial video uses 4:2:0 format, but now 4:4:4 and 4:2:2 video formats are mandated by video interface standards Huai-Rong Shao, et al. (Samsung)

  4. Data rate examples Data Rate of Uncompressed Video Note: Huawei’s contribution 11-13-0527r2 has a similar table on 4k and 8k video Huai-Rong Shao, et al. (Samsung)

  5. Data rate of compressed video depends on the compression ratio • Two major video application areas • Pre-stored video such as TV broadcasting and Blue-ray movies • High compression ratio: can go up to several hundreds (MPEG, H.264 and now HEVC) • Long latency: Both intra-frame and inter-frame video processing, also multi-frame reference schemes • Real-time video such as 60GHz display extension • Low compression ratio: usually at the order of 10 • Low-latency: Mainly intra-frame video processing Data Rate of Compressed Video Huai-Rong Shao, et.al. (Samsung Electronics)

  6. Thank you! Huai-Rong Shao, et.al. (Samsung)
