EVER-INCREASING QUALITY FOR STORED VIDEO STREAMING IN A MOBILE WIRELESS INTERWORKING ENVIRONMENT.

摘要

There is provided a method for managing the downloading and display of a video program using a mobile device in an networking environment that includes a first radio acccess nework (210) and a second radio access network (220) that has a faster transfer rate than the first network (210). A layer of video program (310) that has been encoded into multiple layers is downloaded via the first or second network (210 or 220). The downloaded video program (310) is displayed at a playback rate that corresponds to a display quality. Excess portion (320) of the downloaded video program that result when a rate at which the video program is displayed are buffered. The number of layers being downloaded and the playback rate at which the video program is displayed are increased (330) to increase the display quality, when the buffered excess portions exceeds a threshold level (325).
