Abstract

A method of providing improved quality of Internet Protocol (IP) video content over the Internet involves, for an item of content, calculating a score representative of a likelihood that a particular viewer will order the item of content; if the score is greater than a threshold score T, then downloading a portion of the item of content from a content provider, and storing the portion of the item of content in a storage location local to the viewer; if the viewer elects to view the item of video content, then: retrieving the stored portion of the item of video content, streaming an augmentation to the stored portion of the item of video content from the content provider, and combining the stored portion with the augmentation of the stored portion to produce an improved resolution version of the item of video content. This process can be carried out in an IPTV adapter. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

3. The method according to claim 1, wherein one of the stored portions and the augmentation of the stored portion comprise high frequency components of the video content.

4. The method according to claim 1, wherein one of the stored portions and the augmentation of the stored portion comprise one of spatial sub-sampling, frame sub-sampling and time sub-sampling.

5. The method according to claim 1, wherein the score is comprised of a summation of score components.

6. The method according to claim 5, wherein at least one of the score components comprises a score component representing a general popularity of the item of content, a score component representing an analysis of the viewer'"'"'s viewing habits as they relate to the item of content, and a score component representing a viewer'"'"'s direct input regarding the item of content.

7. The method according to claim 5, wherein the score components are weighted by a plurality of weighting factors.

8. The method according to claim 7, wherein the weighting factors are dynamically altered by feedback.

9. The method according to claim 1, wherein once the stored portion of the item of content is stored, the score of the item of content is modified.

10. The method according to claim 9, wherein the score is modified based upon a plurality of score components.

11. The method according to claim 10, wherein the plurality of score components comprise at least one of:

a score component representing a general popularity of the item of content, a score component representing an analysis of the viewer'"'"'s viewing habits as they relate to the item of content, a score component representing a viewer'"'"'s direct input regarding the item of content, a component of passage of time, a score component representing remaining storage capacity, a score component representing viewing of the content, and a score component representing direct viewer intervention.

12. The method according to claim 10, wherein the stored portion is purged when its score drops below a specified threshold.

13. A computer readable storage medium storing instructions which, when executed on a programmed processor, carry the method according to claim 1.
