High quality sound reproduction can be achieved by digital transmission techniques, high quality still picture reproduction such as image sharpness, high image stability and faithful color reproduction can be achieved by digital transmission technique as well.: AHD is a disc system that records and reproduces digital information signals with the same way as VHD does. AHD has four digital transmission channels, each transmitting 88.2 K bytes data per second. Each channel transmits digital data such as high quality audio, still picture and computer data. The memory size of the still picture is 384 KB, it requires 2.4 seconds to send full picture frame using two digital channels.: This paper discusses digital still picture systems in relation to AHD and high definition TV applications.
