Abstract:
1. A contents distribution system for distributing contents from a distribution server to a display terminal, wherein said distribution server detects a region in which a character is displayed from an image of video contents, generates character information for use in confirming said character displayed in said region detected and distributes said character information generated to said display terminal at a low bit rate, wherein said distribution server distributes said video contents to said display terminal simultaneously with the character information of said video contents, and said display terminal presents the character information of said video contents received from said distribution server together with said video contents received simultaneously, wherein the character information obtained from the image of video contents is encoded at a higher resolution than non-character information of the image of video contents prior to being sent by said distribution server to said display terminal, wherein said distribution server transmits character subsidiary information including position information of said region detected to the display terminal, accepts designation of said region from said display terminal, generates alternatively an image of designated region having high resolution or character code obtained by character read from said designated region, and distributes said image of said designated region or said character code as the character information to the display terminal.
