Audio Codecs

Our full spectrum Muzip codecs deliver MP3 quality audio at up to four times the compression rate. Audio files compressed with our latest Muzip4 deliver MP3 quality audio in one quarter of the file size. The Muzip codecs have been field tested in our Gummy MP3 players (http://www.gummymp3.com) with overwhelming success.

MUZIP is a general purpose audio codec designed to produce mono and stereo audio streams from 10 kbps to 64 kbps. Stereo audio when compressed using MUZIP at 32 kbps sounds very close to MP3 quality. Compressed audio streams at 48 kbps and 64 kbps equal or exceed MP3 quality.

Applications for the MUZIP codec include MP3 players, "Click and Play" streaming over the Internet, low bit rate playback using very small Java players, etc.

TELP is our speech codec designed specifically for low data rate compression of human speech. Data rates as low as 4.8 kbps can produce excellent quality audio containing male or female speech. Our latest TDAC-S speech codec compressed audio data streams from 10 kbps to 16 kbps with a minimum demand on compute resources making it ideal for low cost voice recorder and Java based recorder applications.

Video Codecs

LittleBits is a highly optimized video codec designed to allow very small Java applications to play back the video and audio content. A modified version of MUZIP is used in LittleBits to enable a Java player of less than 15 K bytes to play back both the audio and video data.

BigBits is a proprietary video codec capable of delivering near DVD quality video at significantly greater compression rates. When compared to MPEG, BitBits produces video files up to 2.5 times smaller with comparable video quality. Used for compression of XVD files, BigBits enables users to store an unprecedented 150 minutes of video on a single CD. Combined with the advanced XVD players, an auto play CD containing an entire movie can be played back on any Windows PC merely by inserting the CD into the PC's CDROM drive.

Our Domen video codec preceded Littlebits and used a Java player of approximately 60 KB. The Domen codec can produce better quality in specific instances but has for the most part been replaced with Littlebits.

Streaming and Playback Technology

All of our codecs have been designed to play back with the minimum amount of compute resources. Depending on the codec, we have implemented either very small Java players or very efficient ActiveX controls that can be easily downloaded over the Internet. In some cases, we have also ported our players to very inexpensive DSP's for implementation into low cost products like MP3 players.

Videograms

Videograms are self-contained emails that combine graphics, audio and video content into a compact HTML file that can be played back on any Windows or Macintosh PC. Other than a browser containing a Java Virtual Machine, no special hardware or software is required to play back the Videogram.

Using proprietary compression techniques, the entire content of the web page is enclosed in the HTML file except for the Java applets used to play back the file. And since the Java applets are so small (less than 15KB), the latest versions of the players can be downloaded in seconds over the Internet when the user wants to play the Videogram.

We introduced Videogram video email in 1995 and have since improved significantly on the underlying technology. In its' latest release, Videogram Creator has solved the problems of system security and cross platform compatibility by using very small Java players for the playback of received video mail. Because Java players only use the limited resources available to it from the Java Virtual Machine, system resources are protected to the same degree as from any web page containing Java content. And since many platforms support Java including Macintosh's and some PDA's, Videograms will play on many different targets without translation. The Videogram implementation is so unique that we have filed a patent on how a Videogram is delivered completely contained in a HTML file.

Encoding Solutions

All of our encoders have been developed on Windows platforms and in the case of lower bit rates and resolution execute in real time. In some cases, we have ported our encoders to hardware platforms for higher speed encoding. These hardware platforms allow us to encode voice, music or high-resolution video in real time. Please contact us for more information on our encoding solutions.

Patents and Other Intellectual Property

We have a number of patents on our audio and video compression technologies and have in process other patents that cover our latest ideas and techniques. Acknowledging our limits in time and resources, we have purposely chosen not to submit for the patent process all of the algorithms and techniques that are contained in our intellectual property. In some cases, this was done to protect specific ideas and approaches that could not be fully protected by a patent. Instead we have chosen to dedicate our resources to develop the very best products that we can utilizing all of our intellectual property - patentable or not. We believe that this strategy will allow us to respond in the most responsive and timely manner to our customer's specific requirements.
