VIA VX11 Media System Processor: Breathing Life into 3D and High Definition Video Playback

This product is available fully ROHS-compliant.

The VIA VX11 media system processor (MSP) family is designed for next generation desktop, small form factor and all-in-one PCs, offering a world-class HD multimedia platform for media-intensive applications. The VIA VX11 features the VIA Chrome® 640\645, a genuine DirectX11 graphics processor that offers richer visual and 3D contents for immersive environments.

The VIA VX11 DX11GPU is designed to leverage the power of parallel processing and provides support for sophisticated shading and texturing techniques such as tessellation for smoother 3D animation and more lifelike graphics. Including Shader 5.0 to integrate cohesive post graphic processing, DirectCompute 11 for scalable GPGPU computing, as well as better multithreading and control for parallel computing, the VIA VX11 MSP provides enhanced graphic capabilities for today’s media intensive applications and has been designed to support OpenCL™.

The VIA VX11 MSP has received SuperSpeed USB certification from USB-IF and supports up to 3 USB 3.0 ports for data transfer speeds up to ten times faster than USB 2.0 with optimized power efficiency.

The VIA VX11 MSP features the high-performance and versatile VIA Chromotion 5.0 video processor, providing ultra smooth decoding of MPEG-4, H.264, MPEG-2, and VC-1. It offers advanced filtering and cutting edge post-processing. Support for the latest connectivity standards includes Display Port, HDMI, DVP, VGA and LVDS.

The VIA VX11 MSP supports up to 16GB of the latest DDR3 system memory at speeds of up to 1600MHz and is compatible with the VIA QuadCore, VIA Nano®, and VIA Eden® processor families. Integrating all the features of a traditional North and South bridge solution into a 33mm x 33mm single chip package and leveraging the 40nm advanced manufacturing process, the VIA VX11 is a single chip solution that reduces overall silicon footprint and lowers system power consumption.

VIA Chromotion 5.0

The VIA Chromotion 5.0 is a high performance video processor supports stereoscopic decoding in MVC format bringing 3D content to life. Also boasting hardware acceleration of the H.264 HD encoding technology that is driving today's advanced online HD video streaming services, the VIA Chromotion 5.0 video processor brings crisp, smooth 1080p HD video content to life without hogging key system resources or resorting to an additional third party decoder.

The Chromotion 5.0 video processor supports the latest video codecs including full Blu-ray support at true HD screen resolutions, including dual 1080p HD decode and playback of MPEG-2, MPEG-4, WMV9, VC-1 and H.264 content. Additional enhancements include H.264 HD encoder, motion compensation, transform, de-blocking, full VLD support, and AVS support.

Full frame rate playback of MPEG-2, H.264 and Windows Media Video-based codecs, including VC-1 at full 1080p resolutions, is assisted by hardware acceleration assistance and includes Advanced Profile level 4 support on WMV/VC-1 content and High Profile level 4.1 for H.264-based content.

Advanced Display Connectivity

Integrated display support includes a dedicated CRT interface, integrated LVDS transmitter, a multiplexed display interface for DisplayPort and HDMI and parallel digital video output port (DVP) to external HMDI/LVDS/DVI transmitter. The VIA VX11 MSP provides multi-monitor extended desktop support where two independent display engines can display different content at different resolutions, pixel depths and refresh rates.

VIA Vinyl HD Audio

As the PC platform increasingly becomes the central device for home entertainment, the HD Audio codecs provide home theatre quality performance with support for the latest high definition audio content in Blu-ray and other popular HD audio formats.

The VIA Vinyl HD audio codec is a low power, high-fidelity 8-channel high definition audio codec designed for desktop PC audio systems, supporting QSound, DTS Connect, Dolby1 Digital Live, Dolby PCEE program, SRS Lab and Creative technologies. HD DVD Audi Content protection is also supported for full-rate lossless DVD audio, and HD DVD audio content playback.
