Stream transfer control LSI
MN85620GL
Overview
MN85620GL is an LSI for performing transfer of real-time data
stream, such as video and audio.
This LSI performs CPRM encryption of the MPEG stream from
an encoder, records it on DVD-RAM/R,HDD by software
control, and transfers the stream to the decoder by CSS
authentication.
Moreover, this LSI realizes simultaneous playback and recording
with SDRAM buffer control and internal high-speed data transfer.
