APPARATUS AND METHOD OF STREAMING PROGRESSIVE VIDEO DATA BASED VISION RECOGNITION

摘要

PURPOSE: A visual recognition based progressive video streaming apparatus and a method thereof are provided to reduce a service dissatisfaction which is caused by 'an interactive delay which is generated in a trick mode like a channel change and a concern time point viewing which are used in an interactive video service'. CONSTITUTION: A video reproduction quality selector(103) determines a quality level of a video reproduction based on gaze information which is detected in a gaze detector(102). A progressive streaming receiver(104) requests and receives video data in consideration of 'a visual recognition priority based on the detected gaze information'. A visual recognition-centered player(105) controls and reproduces the video data in order to an interactive delay below a selected standard while reducing 'a quality change which is recognized by a visual sense in the received video data'.
