Abstract:
Disclosed herein are devices and methods to facilitate compensating for intra-pair skew in a high-definition multimedia interface (HDMI) system. One or more skew training pattern may be transmitted on a signal line including a differential pair. Acknowledgment of receiving the skew training pattern may be received on a display data channel (DDC) associated with HDMI system. The skew training pattern may be used to ascertain and compensate for intra-pair skew.
Abstract:
An automation testing apparatus includes a controller that is configured to receive a set of one or more commands that are part of a test and programmatically manipulate a set of components that connect the automation testing apparatus with a device under test (DUT) to test the DUT according to the set of commands. The set of components may include a power switch that is configured to turn on and off power to the DUT, a communication controller that is configured to send commands to be executed by the DUT, and an audio/video switch that is configured to turn on and off audio and/or video of the DUT. The controller logs the set of commands executed and a result of execution of the set of commands to analyze whether the test passed.
Abstract:
Techniques are described for tunneling high definition multimedia interface (HDMI) data over a wireless connection from an HDMI-capable source device to a client device that is physically connected to an HDMI-capable sink device via an HDMI connector. The techniques enable wireless transmission of HDMI data without video compression by using an encapsulation scheme that maps HDMI audio and video channels into a transport stream format and maps HDMI side channels into an IP datagram for transmission over the wireless connection. The source device may operate as an HDMI controller and perform HDMI-based data, control, and security processing required for HDMI connectivity with the sink device via the client device. The client device, therefore, may be a "dummy" client device that does not perform HDMI-based processing, but acts as a wireless HDMI bridge to pass the HDMI data between the source device and the sink device.

Abstract:
A data transmission and reception method for a source device which transmits data using a high definition media interface (HDMI) is disclosed. A data transmission and reception method for an HDMI source device comprises the steps of: when a sink device is connected, transmitting a request for reading extended display identification data (EDID) to the sink device; receiving the EDID including port information of the sink device from the sink device; transmitting operation parameter information determined on the basis of the EDID; and transmitting data through an HDMI.
