Scalable streaming of JPEG2000 images using hypertext transfer protocol.

ABSTRACTThis paper describes a scalable architecture for streaming of JPEG2000 images, using Hypertext Transfer Protocol (HTTP). JPEG2000 is a new image compression standard. One of the goals of JPEG2000 is to support large images. For a large image, even the compressed image file size can be very big. Thus downloading the entire image at its full resolution can take a long time depending upon the user's connection speed. Thus we propose to use streaming of JPEG2000 images. We use Hypertext transfer protocol (HTTP) for streaming. The use of HTTP to stream JPEG2000 images will ease its deployment, because of the widespread availability and accessibility of web servers. Thus JPEG2000 images can be hosted by web server and can be streamed to the client helper application. Our solution is scalable. The clients can view image at a variety of resolutions and quality levels. It is also possible to stream only selected region of the image at a particular resolution and decode this partial stream and display it at the client. Thus client devices with different capabilities, variety of screen resolutions, heterogeneous bandwidths can all achieve a scalable viewing of the same content stored in a single file.
