Abstract: Approaches for encoding/transcoding of digital video based on subjective video quality preferences or display device characteristics or capabilities. A set of esthetic digital video preferences are received from a user via a user interface. The user may be associated with a supplier or provider of digital video or may be a viewer of the digital video. A video quality profile that describes the set of esthetic digital video preferences or the characteristics or capabilities of a display device is created and stored. Upon determining that a video quality profile is associated with a compressed digital video bit stream, a final rate of compression for the compressed digital video bit stream is determined using one or more video quality profiles. In this way, a user's subjective video quality preferences or the characteristics or capabilities of a display device can be considered in encoding/transcoding digital video.

Abstract: Approaches for transcoding on-the-fly (TOTF). A digital video is encoded to produce a set of encoding decisions. A video quality profile is created that describes the set of encoding decisions. Upon determining that the video quality profile is associated with a compressed digital video bit stream, a final rate of compression is determined, frame by frame, for the compressed digital video bit stream using the video quality profile. The final rate of compression may be determined either internal or external to an encoder/transcoder. The video quality profile may be created by reviewing a plurality of encoding decisions to determine which encoding decisions merit inclusion based on a variety of criteria.
