Abstract: An electronic information processing system includes a first information processing device and a second information processing device configured to store electronic information. The first information processing device displays a code in which a URL of a web page is recorded. The second information processing device reads the code displayed by the first information processing device, accesses the URL acquired from the read code to display the web page, and transmits image data to a server device via the displayed web page. The first information processing device receives the image data from the server device.

Abstract: A network connects first, second, and third apparatuses. The first apparatus generates a first list of contents represented by data stored therein. The second apparatus generates a second list of contents represented by data stored therein. The first apparatus gets the second list of contents from the second apparatus, and combines the first list of contents and the second list of contents into a third list of contents. The second apparatus gets the first list of contents from the first apparatus, and combines the first list of contents and the second list of contents into a fourth list of contents which is equal to the third list of contents. The third apparatus refers to one of (1) the third list of contents which is generated by the first apparatus and (2) the fourth list of contents which is generated by the second apparatus.

Abstract: An input video signal is applied to a transmission line first through a time direction emphasizer for emphasizing the levels of time direction high frequency components of the video signal, relative to the levels of low frequency components thereof; secondary through a vertical direction emphasizer; and thirdly through a horizontal direction emphasizer. Further, the received video signal is outputted as an output video signal from the transmission line first through a horizontal direction deemphasizer for deemphasizing the levels of horizontal direction high frequency components of the video signal, relative to the levels of low frequency components thereof; secondary through a vertical direction deemphasizer; and thirdly through a time direction deemphasizer. The emphasis and deemphasis method enables the dynamic range of the transmission line to be utilized effectively, while preventing erroneous operation on the reception side.

Abstract: A video signal recording and reproducing apparatus comprises a magnetic tape (4) into which video signals are recorded. A preemphasis circuit (35) modifies the video signals prior to the recording into the magnetic tape (4), so as to increase magnitude of high-frequency components with respect to magnitude of low-frequency components on time base. A record start or end ID signal is generated in response to a record start or end signal in an ID signal recording circuit (36) which memorizes this ID signal into a corresponding portion of the magnetic tape (4). A mute circuit (46) resets the preemphasis circuit (35) in response to the record start or end signal. There is further provided a deemphasis circuit (37) for modifying the video signals after reproducing from the magnetic tape (4) in a complementary manner with respect to the preemphasis circuit (35), so as to decrease magnitude of high-frequency components with respect to magnitude of low-frequency components on time base.

Abstract: An image is stably reproduced in a special reproduction mode of still, frame advance or slow motion mode without residual image and/or blur. A video signal reproducing apparatus operates to alternately repeat the steps of interrupting a de-emphasizing process at a time at which the de-emphasis process for one video image signal period is completed, holding a content of a frame memory constituting the de-emphasis circuit without refreshing the content and performing a de-emphasis process based the content of the memory during a subsequent video image signal period.
