Abstract: A terminal control system includes a plurality of terminals and a controller which controls the plurality of terminals. Each of the plurality of terminals includes an imager which images a user of the terminal to generate image data. The controller includes: a storage which stores group information indicating grouping of the plurality of terminals; a classifier which classifies each of target terminals included in a same group indicated by the group information among the plurality of terminals into a first group or a second group, based on the image data generated by the imager of the target terminal; and a setter which performs settings of a first type terminal classified into the first group and a second type terminal classified into the second group so that the first type terminal can control the second type terminal.

Abstract: A receiving unit 200 receives, from broadcast stations (10, 11), EPG information related to all the programs to be broadcast on a plurality of channels. A program recommendation unit (300) extracts, from the programs indicated in the EPG information, a recommended program, which is estimated to meet the user's preferences, in accordance with history of program recording or program viewing by the user. A subscription suggestion unit (400) counts the broadcast frequency for each of the channels of recommended programs and for each day, and then compares the counting result with a threshold value, thereby suggesting to the user, via a display unit (20), that he or she makes or cancels any one of subscriptions to the channels in accordance with the broadcast frequency of recommended programs.

Abstract: The plasma display device has a sustain pulse generating circuit for generating sustain pulses in a sustain period. The sustain pulse generating circuit generates at least two kinds of sustain pulses of different rising gradients in the sustain period, generates a predetermined number of sustain pulse whose rising gradient becomes steeper to the latter half in at least one-side electrode in the sustain period after first two sustain pulses and except an erasing pulse, and continuously generates the sustain pulses while the rising gradient of the sustain pulses is varied in response to the light emitting rate of the plasma display panel in the sustain period.
