Signal Source Device
A DVD player of a signal source device generates a video signal and an audio signal, and outputs the signals to a plasma display unit of a signal sink device. The DVD player outputs the video signal and the audio signal to the plasma display unit via a transmission line in conformity with an HDMI standard after elapsing a predetermined waiting time, which is set to be longer than a time required for an initial start setting process by the plasma display unit after completion of equipment authentication with the plasma display unit.

18 . The signal source device as claimed in claim 14 , further comprising a non-image silent signal generator, which generates a non-image silent signal having predetermined specifications, and outputs the non-image silent signal to the signal sink device,
wherein the controller generates the non-image silent signal after completion of the equipment authentication, controls the non-image silent signal generator to output the non-image silent signal to the signal sink device, and controls the non-image silent signal generator to stop generation and output of the non-image silent signal after elapsing the waiting time.
19 . A method of controlling a signal source device for generating at least one of a video signal and an audio signal, and outputting the signals to a signal sink device via a transmission line in conformity with a predetermined standard, the method including the following steps of:
outputting at least one of the video signal and the audio signal to the signal sink device after completion of equipment authentication with the signal sink device; and
outputting at least one of the video signal and the audio signal to the signal sink device after elapsing a predetermined waiting time, which is set to be longer than a time required for an initial start setting process by the signal sink device, after completion of the equipment authentication.
20 . The method of controlling the signal source device as claimed in claim 19 , further including the following steps of:
outputting at least one of the video signal and the audio signal to the signal sink device via signal repeater unit; and
outputting at least one of the video signal and the audio signal to the signal sink device after completion of equipment authentication between the signal source device and the signal sink device, and equipment authentication between the signal repeater unit and the signal sink device.
21 . The method of controlling the signal source device as claimed in claim 19 , further including the following steps of:
receiving data including at least one of identification information, video output specifications, and audio output specifications of the signal sink device; and
determining the predetermined waiting time on the basis of the received data.
22 . The method of controlling the signal source device as claimed in claim 19 , further including a step of inputting the predetermined waiting time to the signal source device.
23 . The method of controlling the signal source device as claimed in claim 19 , further including the steps of:
generating a non-image silent signal having predetermined specifications after completion of the equipment authentication, and outputting the non-image silent signal to the signal sink device; and
stopping generation and output of the non-image silent signal after elapsing the waiting time.
24 . A program which can be executed by a computer, including the following steps for use in a method of controlling a signal source device for generating at least one of a video signal and an audio signal, and outputting the signals to a signal sink device via a transmission line in conformity with a predetermined standard:
outputting at least one of the video signal and the audio signal to the signal sink device after completion of equipment authentication with the signal sink device; and
outputting at least one of the video signal and the audio signal to the signal sink device after elapsing a predetermined waiting time, which is set to be longer than a time required for an initial start setting process by the signal sink device, after completion of the equipment authentication.
