AUTO DETECTION AND ADAPTIVE CONFIGURATION OF HDMI PORTS

摘要

Methods, systems, circuits, devices, and apparatuses are described for auto-detection and adaptive configuration of high-definition multimedia interface (HDMI) ports. Unique systems and circuits allow HDMI repeaters to automatically detect if an HDMI device that has been connected thereto, via an HDMI port, is an HDMI source (source mode) or an HDMI sink (sink mode). The unique systems and circuits may be adaptively configured to allow the HDMI port to function as an HDMI input or an HDMI output based on the automatic detection. Methods corresponding to the functions performed by the systems and apparatuses are provided, and computer readable storage media with computer program instructions encoded thereon for enabling processing devices to perform the methods are also provided.

主权项

1. A high-definition multimedia interface (HDMI) circuit that comprises:
a first detection component configured to receive a signal from a first HDMI connector and detect from the signal from the first HDMI connector first indicia of an operational mode of a first HDMI device connected to the first HDMI connector; a second detection component configured to receive a signal from a second HDMI connector and detect from the signal from the second HDMI connector second indicia of an operational mode of a second HDMI device connected to the second HDMI connector; a control component configured to:
receive the first indicia and second indicia, andprovide one or more configuration control signals based on the first indicia or the second indicia; and a switching circuit configured to:
receive the one or more configuration control signals, andprovide a connection, based on the one or more configuration control signals, between either of the first and the second HDMI connectors and either of a receive circuit or a transmit circuit of a transceiver that is configured to receive HDMI signals at the receive circuit and to transmit HDMI signals from the transmit circuit.
