[Object] To make it possible to control a CEC-non-compliant device connected to a television receiver by using a remote control sender of the television receiver. [Solving Means] The fact that a physical address [2000] is a device (Recording Device) that a photo playerB controls in place of the physical address [2000] is set by a user in the photo playerB. In accordance with this setting, the photo playerB decides a logical address {1} as a CEC-controlled Recording Device. When the user operates a disc recorderB that is a CEC-non-compliant device by using a remote control sender, a television receiverB generates a CEC control command addressed to the disc recorderB. The photo playerB detects the CEC control command, converts the CEC control command into an infrared remote control command, and sends the infrared remote control command from an infrared sending unitto the disc recorderB.

Electronic device and control signal sending method in electronic device

Disclosed herein is an electronic device that is connected to one or more other devices via a specified signal line and capable of operating in accordance with a control signal transmitted from any of the one or more other devices connected to the electronic device. The electronic device includes: a reception section configured to receive the control signal transmitted from any of the one or more other devices connected to the electronic device; a control section configured to perform a specified process if, after receiving a specific control signal, the reception section does not receive a control signal corresponding to the specific control signal within a set signal waiting period; and a waiting period adjustment section configured to adjust the signal waiting period based on traffic in the signal line.

Electronic device and method for controlling the same

An information processing apparatus configured to connect an external device in conformity with a predetermined interface specification, includes: a control LSI configured to control signal output to an external device effectively connected; and a CPU configured to control the operation within the apparatus including the control LSI as a whole; wherein the CPU includes an interface circuit connected to a detecting unit configured to detect the validity of connection to an external device, a control LSI control unit configured to control reset of the control LSI, and release of the reset state of the control LSI according to the detection result of the detecting unit, and the control LSI.

Connection detecting information processing apparatus

An electronic appliance which is carried by a user, the electronic appliance includes: a first processor configured to perform a first operating system, and to perform a first process of a user interface when the booting of the first operating system is completed; and a second processor configured to perform a second operating system which is booted within a shorter time period than the first operating system, to perform a second process of a user interface in which a user instruction is acquired from an input unit shared by the first processor when the booting of the second operating system is completed, and to suppress execution of the second process of the user interface when the booting of the first operating system is completed.

Electronic appliance and startup method

A wave-form observation apparatus i.e. a digital oscilloscope configured to store and display wave-forms being displayed by a simple operation is disclosed. The analog input picture signal,includes wave-forms, characters and figures with their intensity information. The analog signal,is A/D converted to a picture data,. A subtracted picture data,is obtained by subtracting a predetermined value from an intensity of the stored picture data,. Two intensities of the data,and,are compared. In a ready state for the memory operation, the predetermined value is set to zero, By pushing a button,, the picture data,having strong intensity is selected in the switch S,to obtain intense picture data,. Thereafter the switch S,selects the data,which is equal to the intense picture data,in their intensities. Thus the stored picture data,is repeatedly displayed in the memory operation.

Wave-form observation apparatus

An oscilloscope intensity regulation apparatus is disclosed. The oscilloscope displays wave-forms with the regulated intensity in spite of various wave-form repetition rates or sweep ranges. The scope has a CCD sensor,on a CRT,. The CCD output,is applied to a video circuit,delivering a video signal,. The CPU,instructs an intensity of an electron beam to a Z-axis circuit,and an AGC (automatic gain control) revision signal,to a AGC circuit,in accordance with an intensity input signal,. The AGC circuit,controls its gain for amplifying a video signal,from the CCD,via the video circuit,. When the video signal,is small in its amplitude, the AGC circuit,has a large gain. When the video signal,is large, the circuit,has a small gain. Therefore, an intensity of wave-forms being displayed is regulated in the intensity desired, in spite of various repetition rates of the wave-forms or sweep velocities.
