There is provided a display device including a signal receiving unit for receiving a video signal from an external device via a transmission path through a plurality of channels using a differential signal, an information receiving unit for receiving program information from the external device using a bidirectional communication path including predetermined lines of the transmission path, an image display unit for displaying images on image display elements based on the video signal received by the signal receiving unit, and a program information display unit for displaying the program information on the image display elements based on the program information received by the information receiving unit.

Display device, program information display method in display device, receiving device, and signal transmission method in receiving device

Provided is a display apparatus including a first signal receiving unit that receives a non-compressed video signal from an external device via a first transmission path through a plurality of channels by means of a differential signal, an image display unit that displays images by processing the video signal received by the first signal receiving unit, a second signal receiving unit that receives a compressed video signal of a same video source as the non-compressed video signal by using a bi-directional communication path configured by predetermined lines of the first transmission path, and a signal transmitting unit that transmits a compressed video signal corresponding to the compressed video signal received by the second signal receiving unit to another external device different from the external device.

Display apparatus, video signal transmission method for display apparatus, transmitting apparatus, and transmission method of video signal

There are provided a transmitter, a display, a shutter eyeglass device, a transmission/reception system, a display system and a transmission/reception method allowed to achieve highly reliable communication between a transmission side and a reception side. The transmitter includes: a transmission section holding plural kinds of commands each represented by a plurality of bits and repeatedly transmitting a command set, the command set being configured of one or more kinds of commands which are selected from the plural kinds of commands and combined in predetermined order, in which a bit pattern representing a whole of the command set is the same as a bit pattern held in a receiver.

Even if contents data distributed over a network are once destroyed, the contents data are restored, as the copyright protection is maintained. A PC memorizes backup of distributed music contents on a hard disc, at the same time as it transmits the using log information of the music contents stored in the hard disc to an EMD server. If the music contents in the hard disc are destroyed, the PC acquires the using log information from the EMD server to reproduce the backup data memorized in the hard disc depending on the using log information.

Contents furnishing system

An information processor for preventing information contained in a file, which has a first area storing first data, a second area storing second data and a third area, from being lost when a format of the file is transformed includes extension unit for extending the second area, a first storage for storing the first data, which is stored in the first area, in the third area, a format analyzer for reconstructing the second data stored in the second area on the basis of a first format and an extended area storage for storing the reconstructed second data in the extended second area.

Information processor, information processing method, program and recording medium

There is provided a processing apparatus which increments and thereby restores a lendable number upon receiving a content returned from a portable device, and which confirms the return of the content and increments the lendable number even when the portable device does not have or deletes the content borrowed from the processing apparatus before returning the content.

Information-processing device, information-processing method, recording medium, and program

There is provided a personal computer which increments and thereby restores a lendable number upon receiving a content returned from a portable device, and which confirms the return of the content and increments the lendable number even when the portable device does not have or deletes the content borrowed from the personal computer before returning the content.
