As a couple of other replies have mentioned, progressive transmission has been documented in the literature extensively for some time, but it may be difficult to get some introductory material together. One of the best references for image compression issues in general (that also covers progressive transmission) is a book available directly from SPIE (or phone ordered) as follows:Digital Image Compression Techniques Majid Rabbani and Paul Jones SPIE Tutorial Text Series, Vol TT7 SPIE Press, Bellingham, WA Phone orders: (206)676-3290
I'll admit to having a bias for this work, since I have worked with the authors for quite a few years at Eastman Kodak. As a single reference, the book is a comprehensive (and understandable) source for technical information on progressive transmission and other compression techniques.
It has a description of both variable amplitude and variable resolution (pyramidal) progressive transmission schemes and also has image examples.
