video CD (VCD)
The Video CD( VCD) is to be regarded as the forerunner of the DVD-Video. It was developed by Sony, Matsushita, Philips and JVC and dates from 1993 and refers to the White Book. Video CDs are used in DVD players, personalcomputers and game consoles.
The storage capacity of the video CD was only sufficient to store about one hour of video, compressed with MPEG-1 audio. Video resolution is 352 x 288 pixels at 25 frames for PAL, and 352 x 240 pixels for NTSC. Still images have a resolution of 720 x 576 pixels. The aspect ratio deviates slightly from the 4:3 aspect ratio. The data transfer rate is 1.15 Mbit/s. The VCD is comparable to VHS in picture quality. As audio compression, the VCD uses MPEG-1 audio, the sampling frequency is 44.1 kHz and the constant bit rate is 224 kbit/s.
The successor technology of Video CD (VCD) is Super Video CD( SVCD).
