  • Patent number: 9465424
    Abstract: In a particular embodiment, an electronic device includes a direct current (DC) voltage source coupled to a DC interface. The electronic device includes a receiver sense circuit configured to detect a connection of the electronic device to a sink device via a connector without consuming power from the DC voltage source. The electronic device further includes a controller coupled to a hot plug detect (HPD) interface. The controller is configured to receive a detection signal from the receiver sense circuit, selectively control a switch to enable and disable the DC voltage source based on the detection signal, detect an HPD signal at the HPD interface after enabling the DC voltage source, and disable the receiver sense circuit in response to detecting the HPD signal.

  • Patent number: 8674679
    Abstract: Power saving for hot plug detect (HPD) is disclosed. In a particular embodiment, a method includes detecting, at a source device that is connectable to a sink device, a connection of the source device to the sink device via a connector. The source device includes a DC voltage source and the connection is detected without consuming power from the DC voltage source.

  • Patent number: 7486828
    Abstract: A technique of processing an image data for output on a digital image device that compresses (164) a portion of a received image data to a data frame (110) according to a predefined size that is optimized for output with a processor of the device. The portion of the image data that is defined by the data frame is outputted (166, 186) to another source, and for any empty bits in the data frame, a zero bit is inserted (174).
