DS-400xHCI

4 or 8 Channel PCI MPEG4 AVC / H.264 Encoder

Available as DS-4004HCI for 4 channels, and DS-4008HCI for 8 channels

Overview:

The DS-400xHCI is the only real time MPEG4 AVC / MPEG4 Part-10 / AVC / H.264 Encoder available on the market. It implements H.264 / MPEG-4 AVC video compression and OggVorbis audio compression in real time. This new standard has a much higher compression ratio, yet higher picture quality compared to standard MPEG4.
At the same video quality, the bit rate is about 40% lower than MPEG4-ASP. The perfect synchronization of audio and video ensures that it can be used in many applications. The DS-400xHCI is mainly intended for the CCTV DVR and Video Surveillance market but can also be used in Distance Learning and Video Streaming applications.

With the embedded encoder SW, 4 video and 4 audio(DS-4004HCI) or 8 video and 8 audio(DS-4008HCI) streams can be encoded simultaneously in real time. All parameters for each channel can be set or adjusted independently. The A/V streams are fed into the memory of the video display adapter directly without consuming any CPU MIPS.

The DS-400xHCI is supported under Windows and Linux. We do not give out source code for the drivers. For support of other versions, please contact us.

Software:

DSP Research provides SDKs to minimize your development cost when you develop your own DS-400xHCI software to suit your particular needs. The following SDKs are currently available from DSP Research:

	Encoder SDK
	Decoder SDK
	Net SDK

Download the latest version of the SDK here.

DSP Research also provides demo applications that use the SDKs. The source code for some of these applications has been included in the SDK to get you started 'on the fly' and further decrease your development time. The following demo applications are currently provided by DSP Research:

Encoder:

	H.264 Demo Encoder (source code is included)
	H.264 Demo Encoder for LINUX (source code is included)
	H.264 Demo Streaming Server (source code is included)
	H.264 Demo Streaming Server for LINUX (source code is included)

Decoder:

	Multimedia Player (source code included)
	Multimedia Player for LINUX (source code is included)
	Windows Media Player Plug-in
	H.264 Demo Client (source code is included)
	H.264 Demo Client for LINUX (source code is included)

System Requirements:

Here follows a summary of the System Requirements for the Encoder PC.

	CPU - Genuine Intel Pentium 4, Preferable 1.6 GHz or greater
	Motherboard - ASUS P4B, P4T, P4B266 - OR - Gigabyte P4 Titan Motherboard (preferably use an Intel Motherboard with Intel chipset).
	RAM - Min 256 MB RAM (suggested 512MB)
	Operating System - Win 2k/XP
	Graphic Card - See the DS-400x FAQ section

Application Notes:

The DS-400xHCI boards are mainly intended for the surveillance market and low resolution applications. Below are some samples on how the DS-400xHCI, H.264 Encoder, can be used in a complete system for different applications

	Surveillance
	Streaming Video
	VIDEO Conferencing over IP

Since the system layer of H.264 is not standardized, decoders from other vendors will not be able to decode the bit stream generated by the DS-400xHCI encoder.
