JPEG2000 (J2K) to compress the video on three concepts: storing the video sequence frames to provide quality and spatial resolution scalability, prediction and conditional replenishment of code-blocks. B-frame technique is employed to compare the video. This paper provides considerably better interactivity compared to existing schemes and can adapt immediately to interactive changes in client interests.

INTRODUCTION JPEG Due to the increasing demand for amazing graphic design in low-band on the one hand and in heavy duty applications such as GIS on the other, image compression has gained great attention over the last two decades. Video takes up a lot of space, so video must be compressed before it is put on the web. “Compressed” just means that the information is packed into a smaller space. JPEG is the "Joint Photographic Experts Group" is used to compress the image /video. Typically compression will be of 10:1 ratio with loss in the image quality. A photograph that takes 1 MB to store in a Windows BMP file can usually be compressed down to 50 KB with JPEG. JPEG2000 (J2K) The compression rate can still improved by JPEG2000 (J2K) which is the advance version of JPEG. J2K not only increase the compression rate but also improved scalability and editability. Very low and very high compression rates are supported in JPEG 2000. JPEG 2000 compresses the video using wavelet technology. Advantage of JPEG 2000 is its ability to display images at different resolutions and sizes from the same image file. Because JPEG 2000 is based on wavelets, the wavelet stream can be only partially decompressed if the user only wants a low-resolution image, while the full resolution image can be viewed if this is desired. If an image was available for download on the Internet, someone with a fast Internet connection could download the full resolution image, while someone with a slower connection could choose to save time by downloading a lower-resolution image. The ability to display a single file with different resolutions also promises to be helpful in many industry applications where a certain image may need to be displayed with only a low resolution at times, while in other processes a clearer picture may be needed. Using JPEG, a different file would need to be generated for each picture. Using JPEG 2000, the same image file could be used, and the user could choose at what resolution to display the image [4, 5]. IMPLEMENTATION OF THE PROPOSED SYSTEM The video is encoded by extracting avi file from the data base. Video coding is done by using JPEG2000, before we approach to the encoder part the video should be pre-processed. The pre-processing stage preparers side-information of frames. Then the user will have two choice: 1) Spatial Scaling: In spatial scaling the original video can be reduced to half or quarter size. Here the original image is reduced to half. 2) Region of Interest: In region of interest the user can select the interesting part of the video so that only that part will be of high resolution and remaining part will be of low resolution. Input to J2K encoder is either of the above choice. Block diagram of "Flexible video encoding uses JPEG2000 (J2K)” is shown in figure 1. Research Article
