- Huffman encode Motion Estimation Table A simplified version of Huffman is used to encoded the motion estimation table.

- Compress half/full/residual image into JPEG
If the number of new+moved blocks is over 70~, the frame is classified as full frame.
Full frames will be compressed as JPEG images. Since key frames require a lot of storage even after JPEG compression, there are two ways to reduce the storage.
1. Full frames can be scaled down to lower the bitrate.
2. Continuous Full frames can be compressed with lower Quality - Construct new History Frame Based on the Motion Estimation Table, moved blocks and no-change blocks are copied from History Frame to the New Frame bitrate, too high/low.

A 3 second moving average is used to predict the current bitrate seconds ahead and start changing the quality before the bitrate is The Error level used in Motion Estimation is hooked to the JPEG
Since the quality of the JPEG compressed image degrade as the quality goes lower, we can relax the motion estimation matching criteria. Linear interpolation is used to adjust the error level threshold.

About the Developers Q. What do you mean by'playerless'?
Buy Vic~eoCli~..ostrea~nNo player is needed to view the video with i'ISectic~r~ VideoClipstreamT"' installed.
All the software needed is on the server-side and in the browser Java. All platforms that support t-~arpe accepted Java standards should be able to view the clips.
Q. What is the advantage of being a playerless technology? r~
r Sites using VideoClipstreamT"' won't need to support a variety of video streaming standards or rely on site visitors already having a player installed. Web surfers just want to see the video without waiting to install a needed player or upgrading the one they already spent twenty minutes downloading.
Q. What will be the pricing structure for VideoClipstreamT""?
This has yet to be determined. If you would like to discuss strategies for using VideoClipstream~~ you can contact our sales d~ artment.
Q. What is the process for encoding existing footage into VideoClipstreamT""?
VideoClipstreamTM is encoded using our ~lut~in for Adobe Premiere 5.1 and higher.
Q. What are the browser requirements for VideoClipstreamT""?

Q. Will there be a live video component for VideoClipstream T""?
Yes. This was one of the first applications tested.
Q. Can VideoClipstreamT"" feeds be saved or downloaded?
No. VideoClipstreamT"" is a streaming product. However, this has advantages for content providers who wish to protect their content.
Q. How can I'test out' VideoClipstreamTM?
Our samples have 28, 56, 150, 300 and 800k bit buttons. Push them to see the quality difference. The other quality differential will be in the bandwidth of your server and that of your site visitors. See our demo section here.
Q. When will VideoClipstreamT"" be available for sale?
VideoClipstreamT"" 1.0 has been released.
Sales requests are handled by our sales de ar~tmer~t.
Q. Will I be able to view VideoClipstreamT""
on my WebTV appliance?
No. This is because WebTV still does not and perhaps will never support Java, despite many calls for it to do so. See the following articles for more information on this:

FAQ The hunger for full motion video over the Applications Internet hit the web full force this year. Millions of web surfers waited for hours to download Technical Info movie trailers, music videos, humorous About the Developers commercials, comedy skits and DV short films.
t3uy VideoClipstream While it's obvious that i~~lp SeGtica~ web consumers want the t~~;~e video experience online, the capacity for the web to meet the demand is still good for a select few.
For those without access to a high bandwidth pipe to the Internet the reality was a long wait, often overnight, before they could view The Lord of the Rings trailer or the latest commercial off Adcritic.com.
VideoClipstreamT"" can help you reach the vast majority of others who still use 56k or lower speed modems. With VideoClipstreamT"' high quality streaming video can convey appealing messages of any length without a prohibitively heavy download for low bandwidth users as well as those with cable / DSL. VideoClipstreamT"' can help you in these developing fields:
Publicity - The use of promotional video on the web has been restricted to high bandwidth users who have the correct players. Stream movie trailers, music videos or commercials.
Corporate Training - Website or intranet based corporate training can be forcefully delivered using streaming video. The java-based approach means reaching the widest variety of machines in the corporate world as possible.
