Title:
ELECTRONIC DEVICE AND METHOD FOR DETERMINING CABLE ADAPTABILITY
Document Type and Number:
WIPO Patent Application WO/2015/151779
Kind Code:
A1
Abstract:
　The present invention enables data transmission using a data channel or a control bus to and from an external device to be performed well. In a source device and a sink device, the number of errors on the control bus is counted for each prescribed time slot, and, when the count value exceeds a prescribed upper limit, an operation mode is switched to a direction in which at least the transmission rate of the control bus is lowered. In the sink device, furthermore, the number of errors on a TMDS channel is counted for each prescribed time slot, and, when the count value exceeds a prescribed upper limit, the operation mode is switched to a direction in which at least the transmission rate of the TMDS channel is lowered.
