Abstract: A motion image distribution system includes a server and a user terminal. The server generates a feature quantity table CHT1 representing a data structure of motion image encoded data VDE, and authenticates the motion image encoded data VDE by using the generated feature quantity table CHT1. Then, the server transmits the motion image encoded data VDE and the feature quantity table CHT1 to the user terminal. The user terminal generates a feature quantity table CHT2 representing a data structure of the received motion image encoded data VDE, and authenticates received motion image encoded data VDE by using the generated feature quantity table CHT2. Then, the user terminal plays back the motion image encoded data VDE and outputs motion image playback information.

Abstract: The movie image retrieving apparatus includes an image input device 13 to which the movie images are inputted in a time-series manner, a feature value calculation device 14 which includes a feature value deriving section 16 for deriving the feature value and a quantization section 17 which quantizes the feature value with a predetermined quantization width to produce the feature value information, a comparative information selection device 15 for deriving the comparative feature value information from the data-base, and a matching device 18 for matching the feature value information and the comparative feature value information using a quantization error. The matching result is outputted from the output device 19. Load on the hardware is reduced and the time required for the search is shortened.

Abstract: Multi-media (MM) information are flexibly reproduced, edited, processed and re-transmitted in conformity with users' needs. A plurality of elements of MM information are distributed, stored and used via a control terminal (4) for distributing and controlling information between a transmission terminal (1) and a reception terminal (2). MM information are stored in a package and distributed. MM information has container information for identifying MM information as one unit, content information constituted of media information itself, and behavior information for manipulating content information. MM information are accumulated and distributed after being compressed, and used after being developed (decompressed).

Abstract: A moving picture search system comprises, for searching, a moving picture input unit for search; and a feature amount calculation unit including a local region extraction unit, a signal extraction unit and a feature amount table creation unit; and, for creating a database, a moving picture input unit for a database; a moving picture database; a feature amount calculation unit including a local region extraction unit, a signal extraction unit and a feature amount table creation unit; a table database registration unit; a table database; a search processing unit including a database read out unit, a matching unit, and a matching result judgment unit; a moving picture database read out unit; and a search result output unit. By calculating the feature amount of the moving picture, it is possible to perform a high-speed moving picture search with a small amount of information.

Abstract: Converting operation information for converting and controlling contents and contents information extracted by the contents distinction section 3 from contents are inputted to the information conversion management section 4. Besides, contents are outputted to the information conversion section 5. The information conversion management section 4 controls the information conversion section 5 in accordance with the converting operation information and the contents information, and the information conversion section 5 converts the inputted contents under control of the information conversion management section 4. Following to the above conversion, the user terminal receives the converted contents provided with a desired quality of contents.

Abstract: The multimedia information processing device includes an internal structural information generator for generating the internal structural information by analyzing the internal structure of the content information, and an operation process information generator for generating operation process information by analyzing the content information. The content information, the internal structural information and the operation process information are unified so that they are processed unitarily. A partial data of the content information is reduced or deleted where the value of the content information becomes low, for example, and the content information a part of which has been reduced can be restored by obtaining the relevant partial data from the producer terminal, if necessary. The hardware resources at the user terminal side are effectively utilized.
