CONTROL OF HDMI DEVICES THROUGH INTELLIGENT EMULATION OF A CONSUMER ELECTRONICS CONTROL PROTOCOL CAPABLE OF EXCHANGING INFORMATION ABOUT CONSUMER ELECTRONICS CONTROL ASSIGNMENT IN A COLLABORATIVE METHOD

摘要

PURPOSE: Control of HDMI devices through intelligent emulation of a consumer electronics control (CEC) protocol is provided to ensure interoperability regardless of different sets of CEC commands.;CONSTITUTION: A CEC bridge performs CEC command transmission and CEC command emulation. The CEC bridge transmits CEC packets between two HDMI networks by using a non-HDMI network. A sink side CEC bridge (140-SNK) emulates a CEC operation of devices in a source cluster. A source side CEC bridge (140-SRC) emulates a CEC operation of devices in an HDMI cluster. The source side CEC bridge emulates an HDMI device (120-SW) and an HDMI device (120-SNK) in a sink cluster and makes HDMI devices (120-SRC-A,120-SRC-B) visible to the HDMI devices.;COPYRIGHT KIPO 2013;[Reference numerals] (140-SNK) Sink side CEC bridge; (140-SRC) Source side CEC bridge; (AA,BB,GG,HH) HDMI device; (CC,DD,EE,FF) Emulated HDMI device
