DSP Decodes Digital Disks

The next-generation HD DVD and Blu-ray high-definition DVD formats will tax systems that need to decode streams with high data rates. Cirrus Logic's single-chip CS49700 audio processor can support the six surround-sound audio algorithms typically found on these discs, including Dolby Digital, Dolby Digital Plus, Dolby TrueHD, DTS, DTS Master, and DTS High Resolution. It handles post-processing algorithms such as Dolby Pro Logic IIx, DTS 96/24TM, Neo:6, MPEG, AAC, SRS Circle Surround II, Dolby Headphone, Dolby Virtual Speaker, SRS Tru-Surround XT, and THX Ultra2. It also supports the HDMI 1.3 interface. Pricing for the 144pin low-profile quad flat package is $7.98.
