ABSTRACT:
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.
