System-on-chip platform for high-speed DVD+R/RW video and data applications

Abstract

This paper discusses the architecture of a highly-integrated subsystem for optical disc engines that operate with write-once (CD-R, DVD+R) and erasable (CD-RW DVD+RW) media. Cost-efficient, high-performance optical disc players and recorders for audio/video and computer applications can be built by using only a few additional integrated circuits (ICs). The described system-on-chip (SoC) has been designed to write DVD+R/RW discs at overspeeds up to 8X and read DVDs at maximum 16X. The operation in the so-called super combo mode is also possible, for which the SoC has been prepared to record compact discs at overspeeds as high as 48X and play them back at 56X.
