A method for distributing advertisement data to display terminal devices from a distribution server via a relay server. The relay server receives status notifications of the display terminal devices and transmits a tenor of receipt of the status notifications to the display terminal devices. The distribution server receiving status notifications and transmits the tenor of receipt of the status notifications to the relay server. The distribution server determines whether the reproduction schedule of the advertisement data has been changed and transmits a notification on a change. If the distribution server receives a request for acquisition of the as-changed reproduction schedule, the distribution server sends the as-changed reproduction schedule to the relay server. If the relay server determines that the reproduction schedule acquired from the distribution server has been changed, the relay server transmits the notification on the change of the reproduction schedule.

Data processing system and data processing method

A data processing system includes a distributing device that distributes edited advertisement data and display terminal devices that display the edited advertisement data distributed to a first place in a predetermined territory. The display terminal devices are each provided with a first reader/writer configured to read out from and/or write in an IC card having stored memory identification data. The data processing system also includes a second reader/writer configured to read out from and/or write in an IC card. The data processing system also includes a hysteresis management device that manages hysteresis data HD, HDfrom the first reader/writer, correlated with the memory identification data, and hysteresis data HDfrom the second reader/writer, correlated with the memory identification data. The data processing system further includes a hysteresis analysis device that correlates the hysteresis data HD, HDfor each of the memory identification data to generate analysis data.

The present invention has non-contact communication means () configured to read a card identifier ID stored in a memory of an IC card, a barcode generation unit () configured to generate a two-dimensional barcode of a bonus data associated with the card identifier ID read by the non-contact communication means (), and a display unit () configured to display the two-dimensional barcode of the bonus data generated by the barcode generation unit (). And, the bonus data displayed on a display unitin the two-dimensional barcode is read by a barcode reader () of a POS terminal ().

Display device, data processing method and data processing system using the display device

A broadcast receiver is provided which can prevent recording of uncopyable contents without failing to record copyable contents. A copy information detecting unit () detects copy control information attached to contents. A discriminating unit () discriminates the copyability or uncopyability. The contents recorded in a user-unreadable recording unit () is transferred to a user-readable recording unit () only if copyable.

Broadcast receiver and recording method

According to the signal processing apparatus of the present invention, in a text signal processing circuit, predetermined signal processes are executed to a luminance signal Y and color difference signals U and V in which a ratio of sampling clocks is equal to (4:4:4) and resultant signals are supplied to a mixing circuit. In a video signal processing circuit, predetermined signal processes are executed to the signals Y, U, and V in which a ratio of sampling clocks is equal to (4:1:1) or (4:2:2). The signal Y is supplied to the mixing circuit through a delay adjusting circuit and the high frequency components are removed from the signals U and V by a band limiting filter and, after that, the resultant signals are supplied to the mixing circuit. The signal mixed by the mixing circuit is supplied to a LPF through a D/A converter. In the LPF, the signal is demodulated by the band limiting filter according to (4:4:4).
