摘要:
The invention provides a control device and a controlled device capable of reducing a management burden on a manufacturer by means of an easy-to-use method. A TV is a control device which controls a DVD recorder, including: a device ID acquisition unit which requests the DVD recorder to transmit a device ID, and receives the device ID from the DVD recorder; a device ID determination unit which determines whether or not the device ID is an initial value; a device ID generation unit which generates a new device ID in the case where the device ID is determined to be the initial value; a device ID update unit which requests the DVD recorder to update to the new device ID; a device ID/attribute information storing unit which stores the new device ID as the device ID of the DVD recorder; and a connected device control unit which controls the DVD recorder by using the device ID stored in the device ID/attribute information storing unit.

摘要:
To provide an audio-video data synchronization method whereby an increase in the amount of control message transmission can be suppressed and the video output can be prevented from being interrupted. The audio-video data synchronization method includes: obtaining, by the audio output device, a first latency that is a period of time taken for the video output device to output the video, by receiving the display identification data that includes information indicating the first latency from the video output device when the indication of the connection validity status information changes from Invalid to Valid; adjusting, by the audio output device, timing of outputting the audio according to the first latency; obtaining, by the video output device, a second latency which is a period of time taken to output the video in the outputting; notifying the audio output device of the second latency by sending a control message from the video output device when the connection validity status information indicates Valid, the control message including information that indicates the second latency obtained in the obtaining of a second latency; and adjusting, by the audio output device, timing of outputting the audio according to the second latency.
摘要:
A communication apparatus (100) of the present invention establishes a one-way data connection and a connection to a network in which a message is transferred in two ways, and includes: a one-way data connection status detecting unit (101) which detects a connection validating request showing a communication apparatus on a data reception side that data transmission, utilizing the one-way data connection, is possible and a connection invalidating request showing that the data transmission is impossible, both of which are outputted from the communication apparatus on the data reception side; an apparatus address obtaining unit (102) which obtains an apparatus address with a message via the network when a change from the connection invalidating request to the connection validating request is detected; an address holding unit (104) which holds the apparatus address; and a message transmission continuing unit (105) which responds to the message received via the network based on the apparatus address held by the address holding unit (104) regardless of whether or not the connection invalidating request is detected.

摘要:
In the case where (i) audio-video data is unidirectionally transmitted between any device, where (ii) control messages are bidirectionally transmitted between all of the devices, and where (iii) a connection between the devices for transmitting and receiving the audio-video data becomes valid when unidirectional transmission of audio reproduction capability information of the reception device from the data reception device to the data transmission device becomes available, the TV (31) includes the audio reproduction capability information of the AV amplifier (21) to the control message and transmits the control message to the DVD recorder (10) (30M3), and in the case where the DVD recorder (10) and the TV (31) are connected such that the audio-video data is unidirectionally transmitted from the DVD recorder (10) to the TV (31), and where the TV (31) and the AV amplifier (21) are connected such that the audio data is output from the TV (31) to the AV amplifier (21) through another network, the TV (31) does not re-transmit the audio reproduction capability information to the DVD recorder (10) using the unidirectional transmission when transmitting the control message.

An object is to provide a peel tester that continuously detects the characteristics of an adhesive tape from the moment an impact is applied to an adherend until the adherend is peeled, and a new method for evaluating the impact peel characteristics of an adhesive tape, which enables quantitative evaluation for the impact peel characteristics by using the test result obtained by the peel tester. Provided is a peel tester 1 with a main body 2, to which an adherend I is to be adhered via an adhesive tape III, for performing a peel test by an impact applied to the adherend I, which includes: a load detection device 6 that detects change in load applied to the adhesive tape I until the adherend I is peeled off from the main body 2; and a displacement detection device 7 that detects change in moving distance of the adherend I until the adherend I is peeled off from the main body 2.
