Main Chipset

The NeuNeo DV308 uses the Amlogic 3288 chipset, which has all the features of the 3285, mentioned below. Additionally, the chipset itself is DivX® Home Theater Certified.

The AML3285/AML3295 A/V Processor is a completely inegrated system targeting all types of Audio/Video decoder applications. The AML3285/AML3295 combines the full functionality of MPEG-2 and MPEG-4 decoding, numerous dedicated and general purpose peripherals and an embedded 32bit host CPU in a single device. The AML3285/AML3295 has two built-in AMRISC 24-bit RISC processors with special instructions to accomodate audio and video digital signal processing.

The embedded 32-bit host CPU handles system initialization, DVD navigation and other systems applications. The AML3285/AML3295 processor provides a glueless interface to all external components: ATAPI loaders, Thomson serial front-end devices, audio DACs and memory. Numerous general-purpose I/O pins can be used to control the front panel display and other miscellaneous tasks. The Flash interface allows the Flash memory to be shared with the front-end chip to reduce system cost in mono-board designs. Together, the embedded host CPU and special glueless interfaces reduce the total system cost for all A/V applications.

The AML3285/AML3295 A/V Processor also integrates an NTSC/PAL TV encoder that supports S-Video, composite, YUV component and RGB signals. The video encoder also supports high-quality de-interlaced progressive scan (480p/576p) with full Macrovision support. Contrast enhancement, hue adjustment, video scaling, video interpolation, pan-scan, letter-box, and zoom are also supported. In addition, four built-in Video DACs complement the video encoder further reducing system cost.

The integrated AMRISC RISC processor is designed to support advanced digital audio processing. The micro-coded engine provides support for all existing audio formats and it also has enough flexibility to accomodate new audio standards. Popular audio formats like Dolby AC3 5.1, DTS, HDCD, MP3 and WMA are supported.
