Methods, systems and content have been developed for increasing the
bandwidth available to a bandwidth-constrained medium for transmitting
digital video content. The content that is to be transmitted is
compressed in proportion to the desirability of the content. The
desirability of the content is determined by obtaining human-factors data
indicative of whether a selected item of content is highly desirable. A
desirability score derived from the data is assigned to the content. The
desirability score determines the compression level. Feedback systems
change the level of compression as the desirability of the content
changes with time.
