  • Patent number: 8274844
    Abstract: To include first and second data input/output terminals allocated to first and second memory circuit units, respectively, and an address terminal allocated in common to these memory circuit units. When a first chip selection signal is activated, the first memory circuit unit performs a read operation or a write operation via the first data input/output terminal based on an address signal regardless of an operation of the second memory circuit unit. When a second chip selection signal is activated, the second memory circuit unit performs a read operation or a write operation via the second data input/output terminal based on the address signal regardless of an operation of the first memory circuit unit. With this configuration, a wasteful data transfer can be prevented, and the effective data transfer rate can be increased.

  • Patent number: 7904813
    Abstract: A regular edition video of a video title is split into shots or scenes with time codes, and provided information, which is the semantic evaluation of the story, is added to the respective scenes to organize the scene score. Necessary scenes for each purpose are extracted on the basis of the scene score and a threshold value (process Pr14). Video characteristic evaluation information is added for each shot constituting each of the extracted scenes so as to organize the shot score (process Pr16). Optimum shots for each of the extracted scenes are selected on the basis of a predetermined rule suitable for the purpose (process Pr16). The optimum shots are sequentially cut out from the regular edition video (process Pr21), thus automatically organizing a preview video suitable for the purpose (process Pr22).

  • Patent number: 7853122
    Abstract: The present invention is relative with a reproducing apparatus and a receiving apparatus for affording the impression or evaluation in line with the intention of a content supplier to the audience. The reproducing apparatus reproduces an optical disc (1) in which the contents and the estimated evaluation values are recorded at the outset. The estimated evaluation values recorded on the optical disc (1) have been set by the content supplier based on estimated impression or evaluation by the audience on the content. As the reproducing apparatus reproduces the content, the apparatus measures the reaction of the audience by a reaction value inputting unit (61), calculates the impression or evaluation by the audience for the content by a recognition evaluation value calculating unit (63) and compares the recognized evaluation values to the estimated evaluation values read out from the optical disc (1) in a control evaluation value calculating unit (53).
