Definition:MPEG-1 video and audio compression standards were mainly devised for CD-ROM applications at 1.5 Mbps.
The MPEG-1 video compression algorithm was optimized for bitrates of 1.1 Mbps since coded video at about 1.1 Mbps and coded stereo audio at 128kbps together match the CD-ROM data rates of approximately 1.4Mbps [2]. SIF was used for optimal performance in MPEG-1 [2]. SIF corresponding to NTSC and PAL have the size of 352x240 at 29.97 fps and the size of 352x288 at 25 fps, respectively.
Key Compression Tools for MPEG Video
All MPEG standards are based on motion compensated transform coding, where main compression tools are following three: 1. Color conversion to YUV and down sampling in UV domain, 2. Spatial de-correlation, and 3. Temporal de-correlation. The video is encoded one macro block (MB) at a time. Each MB corresponds to a 16x16 luma component and the corresponding chroma components. First, UV domain down sampling is adopted to minimize domain resolution in color...
