"DTS" is a registered trademark of DTS, Inc. Note: "AC-3" and "Pro Logic" are registered trademarks of Dolby Laboratories Licensing Corporation. Has a built-in PLL oscillation circuit to generates its own operating clock. Possible to connect most of SPDIF receivers, A/D and D/A converters, by setting I/O data interface format. (at fs= 48 kHz) Reads Dolby Digital (AC-3)/DTS decode information through the microprocessor interface.
to 1.36 second delay time is capable when used with an external 1Mbit SRAM. High performance 25 MIPS programmable DSP suitable for a variety of sound field processing such as original surround, filtering, virtual surround etc.
#DTS DECODER EXTERNAL PRO#
Pro Logic decoding for Dolby digital 2 channels decoded signal as well as ordinary PCM. (when AC-3 decoding) Included de-emphasis filter. Original compression mode as well as four compression modes recommended by Dolby. (possible to decode based on data-stream-number) AC-3 karaoke mode. Possible to decode multi-language encoded data. (Group-A Dolby Digital decoder) No external memory is required (Memory for center and surround channel delay is included) when DTS decoding as well AC-3 / Pro Logic. Dolby Digital (AC-3) / Pro Logic and DTS decode.
Sub DSP is compatible with YSS902, the Sub DSP programs developed for YSS902 are also applicable to YSS912C. Sub DSP is capable of realizing various sound fields, such as virtual surround, by down-loading the program and coefficient. The YSS912C is one chip LSI consisting two built-in DSP's Dolby Digital (AC-3) / Pro Logic / DTS decoder (Main DSP) and a sound processing DSP (Sub DSP).
