Abstract
An HDMI™ (High-Definition Multimedia Interface) switch includes a CEC (Consumer Electronics Control) processor for controlling high-definition audio-visual (AV) equipment. The CEC processor accepts user commands and translates them to control HDMI devices over HDMI; the translations can be manufacturer specific so that devices with different CEC implementations can be combined in a single system. CEC communications between HDMI devices is precluded or at least controlled to avoid problems due to incompatible CEC implementations and unwanted interactions. The CEC processor causes the HDMI switch to appear as an HDMI source to HDMI sink devices and as an HDMI sink to HDMI source devices for the purposes of assigning physical addresses. While CEC is designed to handle AV systems having only one sink (display), the novel HDMI switch provides for CEC-controlled AV systems with multiple displays, e.g., in different rooms.
