Introduction
New
generation TV - Digital TV, equipped large screen, high resolution,
sharp image, good quality and low radiation will be a revolution of
home appliance. It replaces traditional CRT TV to be the main stream,
accompany with digital TV hot market. Digital interface and transfer
is the best way to reduce distortion, no more shown on screen when image
moved. According to the report, currently, 50% of images are stored
in digital, 80% in five years. The quality is not good enough when using
CRT TV display a digital image, despite several times of A/D and D/A
transfer, color space transfer and display driver and circus design
are also the known reason for reducing image quality. Digital TV can
display smooth video image and true color space, just as real scene
shows.
Digital storage access will come to
a new age with Flash memory card introduce to the small portable device,
actually its already popular then any other potable media on digital
storage access, Digital TV should be one of these. With the multi Flash
card reader, Digital TV embedded digital access and media playback function
is the trend from now on. Digital TV Multi-Media Playback Solution provides
any of advantage mentioned above, the market competition will never
loss if the solution attached.
