Digital TVs


MPEG AV decoding (playback) technology is a key element in digital TVs.

Our MPEG AV decoders for digital TVs use NEC Electronics'highly acclaimed EMMA™architecture, thus incorporating in one chip all of the functions required for a digital TV and enabling support of a range of digital broadcast standards worldwide, such as DVB in Europe and ARIB in Japan.
