Abstract

Disclosed is a method to dynamically reduce bandwidth requirements for media in which the audio is the focus while retaining as much of the visual aspect as possible within the bandwidth limitations of the device. The invention provides a novel method to dynamically provide an alternate visual portion of the media, retaining quality at the expense of frequency of updates. It consists of a slide show composed of interesting portions of the video at a frame rate variable based on bandwidth or profile, while leaving the audio element intact.

Dynamic creation of alternate, individual video content for bandwidth constrained devices

Web based media streaming applications are popular for watching music and other types of videos. Particularly in the case of items classified as music videos, the audio portion is arguably more important than the video portion. Video also consumes more bandwidth than audio does. On bandwidth constrained devices or devices in areas with low available bandwidth, there can be extended wait times for buffering, which is highly disruptive to a piece of music, mostly due to the total file size as a result of the video portion.

Other solutions to this problem, known in prior art are to:


• Reduce the quality of the complete stream


• Stop one stream entirely

One solution describes art around basic key frame for previewing. ( http://www.google.com/patents/US20070237225?dq=auto+creation+of+slideshow+from +video+content&ei=JzCgT9zZLM_XiQLw0M2yAg). This disclosure provides a solution that is several steps further than the prior art.

The proposed solution is a method to dynamically reduce bandwidth requirements for media in which the audio is the focus while retaining as much of the visual aspect as possible within the bandwidth limitations of the device. The invention provides a novel method to dynamically provide an alternate visual portion of the media, retaining quality at the expense of frequency of updates. It consists of a slide show composed of interesting portions of the video at a frame rate variable based on bandwidth or profile, while leaving the audio element intact.

The steps for operation include:
