Abstract: A client terminal device and a client server system that can receive operation signals at more suitable timing are provided. In the client server system equipped with a client terminal device and a server device that is connected with the client terminal device through a wireless network, the client terminal device is provided with a buffer that stores content information corresponding to the operation signals from a remote controller sent by the server device, a reception regulation program making CPU inhibit reception of the operation signals sent from the remote controller by the signal reception unit until completion of outputting of the content information temporarily stored in the buffer to an output device after one operation signal has been received from the remote controller, and an informing unit informing inhibition of reception of the operation signals during inhibition.

Abstract: An AV transmission system is structured so that: information of specialized function of a connected AV apparatus is sent from the AV apparatus to a server device and from the server device to a client device, and in case a function menu key is operated at the client device side, functional performances of the AV apparatus corresponding to a plurality of function keys are displayed, and in case the function key is operated, operation information of the function key is sent from the client device to the server device, a command code of the specialized function corresponding to the function key is extracted at the server device, and the command code is sent from the server device to the AV apparatus.

Abstract: A security apparatus and method automatically set and cancel a crime-prevention monitoring mode, while preventing unauthorized control. The security apparatus includes a portable terminal, carried by a person allowed to enter and exit a predetermined area, for transmitting address data identifying the person, an address data memory 34 for registering the address data, a receiver 10 for receiving the address data at the entrance to the predetermined area, a setting circuit 2 for selectively setting the crime-prevention monitoring mode, and a camera 11 for obtaining image data of the person passing through the entrance. A controller starts the camera when reception of the address data is started, and stops the photographing when the reception of the address data is ended. A comparison circuit compares image data stored in an image data memory with image data obtained when the address data is received and cancels the crime-prevention monitoring mode when a match occurs.
