Overview of JPEG standardization committee activities

Editor's Notes

1. Illustrate the gradual increase in complexity and functionality File Format: address the issue of many file formats around and attempts to create consistency/interoperability -> box-based file format based on Apple Quicktime = ISO Base File Format
2. Forward compatibility is the ability of a design to gracefully accept input intended for later versions of itself. The concept can be applied to entire systems, electrical interfaces, telecommunication signals, data communication protocols, file formats, and computer programming languages. A standard supports forward compatibility if older product versions can receive, read, view, play or execute the new standard gracefully, perhaps without supporting all new features. In telecommunications and computing, a product or technology is backward compatible (BC)[1] or downward compatible if it can work with input generated by an older product or technology such as a legacy system.[2] If products designed for the new standard can receive, read, view or play older standards or formats, then the product is said to be backward-compatible; examples of such a standard include data formats and communication protocols. Modifications to a system that do not allow backward compatibility are sometimes called "breaking changes."
