Unprecedented Digital Compression Performance
The DifWav proprietary compression algorithm delivers a 50% - 90% performance advantage over MPEG-4 and h.264 compression.

DifWav Compression Results
|Analog||6 Mbps||JPEG; MPEG-4 | 600 Kbps||120 – 150 Kbps|
|USB||250-300 Kbps||h.264 | 200 Kbps||20 – 60 Kbps|
|IP||1.2 – 2 Mbps||h.264 | 600 Kbps||120-150 Kbps|
This performance advantage leads to:
- Higher frame rates for live streaming video
- Transmitting multiple camera images over a single 3G/4G connection
- Storing digital files in less space
DifWav allows users to accomplish their goals with fewer resources (storage), or viewed alternatively, accomplish more when resources (bandwidth) are constrained.
Direct or Sequential Application
DifWav digital compression can be applied to the initial digital stream or sequentially (to streams already compressed using other standard methods) in order to achieve further compression. The DifWav codec can also be applied to High Definition streams (defined as files from 720 to 1080i). Generally, HD streams compressed with DifWav are about twice the size of the DifWav Compression figures appearing in the last column of the chart above.
DifWav enables high-resolution video in conjunction with an attendant increase in frame rate (20 to 30 fps) while utilizing a relatively small amount of computing resources (CPU and RAM). By doing so, DifWav significantly enhances the capacity of current broadband technologies such as DSL, wireless, 3G/4G and satellite. In addition, DifWav achieves comparable efficiencies when used for storage.
DifWav is offered as an appliance or as software only. DifWav is integrated into Celadon Reef’s CRoS (a Linux from scratch distribution) that runs on most x-86 hardware. DifWav can be deployed in stationary or mobile environments. In conjunction with readily available wireless broadband, a DifWav appliance can be deployed almost anywhere to provide streaming video and remote viewing. Possible applications include:
- Fleet Management: mobile streaming and DVR (digital video recorder) with up to four separate video streams
- Surveillance: ad-hoc video surveillance networks without time consuming provisioning of wireline broadband
- Public Safety: police and first responder proactive, real time streaming video and DVR
