Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiver, a video tape recorder or the like which is operated by an infrared remote controller (hereinafter referred to as a remote controller) and which transmits and receives data through at least a predetermined bus line. The present invention relates to a remote control applied device evaluation apparatus capable of repeatedly and automatically performing inspection and evaluation of remote control applied devices.

[0002]

2. Description of the Related Art Conventionally, as an evaluation device for inspecting and evaluating a television receiver or the like, a signal generator supplies a television signal (video and audio signal) to an evaluation target device while 2. Description of the Related Art There is a well-known evaluation device that evaluates whether or not various operations of a device to be evaluated are executed at correct timing by monitoring data on a bus (called internal bus) of a microcomputer (called microcomputer). .

[0003]

However, tuning in a remote control application device such as a television receiver,
In inspections and evaluations that require remote control operation, such as volume adjustment, the remote control must be actually operated by hand, which is very time-consuming and a problem.

For example, regarding inspection and evaluation of the selection of television receivers, the number of channels of television broadcasting in Japan is UHF, VHF of terrestrial television broadcasting, CATV of cable television broadcasting.
Has 125 channels, satellite television broadcasting BS, C
There are 34 channels of S, 159 channels in total. Therefore, even if the BS / CS tuner is not built in, at least 125 channels must be tested. When this becomes American television broadcasting, there are 68 channels of terrestrial UHF and VHF, 115 channels of CATV of cable television broadcasting, and there are 181 channels to be inspected.

In the conventional evaluation apparatus, it has been necessary to manually operate the remote controller for a large number of channels as described above to switch the channels and to set the output frequency of the signal generator.

Further, in order to display a normal image on the display screen even if the frequency of the channel is slightly deviated, ± several MHz
(For example, for UHF, VHF, and CATV, 2MHz, B
In the case of S and CS, the range of 5 MHz must be the inspection target. Therefore, the inspection and evaluation takes several hours at the shortest, and one day at the longest.

In addition, the above inspection and evaluation must be carried out not only at the time of completion inspection of the product, but also at all channels for all television receivers every time repairs, modifications due to specification changes, and bugs are corrected.

Therefore, of course, it is conceivable to automate the above inspection and evaluation, but in part, various signal generators and bus interface boards are devised so as to be inserted into expansion slots of a computer. However, such a method has a problem in that the evaluation device becomes large in size and is not easy to assemble.

Therefore, the present invention has a problem in a remote controller application device evaluation apparatus which is small in size, easy to use, and low in cost.

[0010]

In order to solve the above problems, a remote control applied device evaluation apparatus according to the present invention appropriately selects a remote control signal output means for appropriately generating and outputting a remote control signal and a television signal. A television signal output means for outputting the signal and a bus line connection means for connecting to the bus line of the video equipment, and sends the remote control signal and the television signal according to a predetermined procedure to monitor the data on the bus line as appropriate. That's what I did.

With the above configuration, even if the initially set inspection items and the like are changed in design for the purpose of inspecting and evaluating the operation state of the device to be evaluated, for example, by version upgrade or bug correction. The same inspection and evaluation can be automatically performed from the second time.

[0012]
