  • Patent number: 9456224
    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.

  • Patent number: 7035875
    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).

  • Publication number: 20020066107
    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.
