A system and method used to configure a smart device to command functional operations of a target appliance. The smart device retrieves from a controllable appliance, such as a settop box, data indicative of a codeset identity of the target appliance wherein the codeset identity was determined during a process used to configure a conventional universal remote control to command functional operations of the target appliance and wherein the process used to configure the conventional universal remote control is performed in cooperation with the controllable appliance. A remote control application resident on the smart device then uses the data indicative of the codeset identity retrieved from the controllable appliance to also configure the smart device to command functional operations of the target appliance.

System and method for configuring the remote control functionality of a portable device

A device receives a request from a controlling device, such as a remote control, smart phone, or the like, where the request is intended to have one or more target devices perform one or more functional operations. The device responds to the request by applying the optimum methodology to propagate one or more commands to each intended target appliance to cause each intended target appliance to perform the intended one or more functional operations.

System and method for optimized appliance control

The present invention relates to a network device for a home entertainment network comprising a network controller adapted to provide Ethernet communication capability, HEC, and CEC, consumer electronics control, communication capability, and a database generator unit adapted to generate a database containing information about a network device of said home entertainment network, and a unique identifier of the respective network device.

Address mapping in a HDMI network

There is provided a communication apparatus capable of performing HEAC communication with another communication apparatus compliant with HEAC communication, comprising: a receiving unit configured to receive an HEC signal from the other communication apparatus via a transmission path; a detecting unit configured to detect a signal level of the HEC signal received by the receiving unit; a deciding unit configured to decide an amplification factor of an HEC signal to be transmitted based upon the detected signal level in a case where the detected signal level is not within prescribed limits; an amplifying unit configured to amplify the HEC signal to be transmitted at the decided amplification factor; and a transmitting unit configured to transmit an HEAC signal, which includes an ARC signal and the HEC signal to be transmitted amplified by the amplifying unit, to the other communication apparatus via the transmission path.

Communication apparatus and method of controlling same

An A/V receiving apparatus is disclosed. The A/V receiving apparatus includes a first interface connected to a display apparatus, a second interface connected to an audio signal output apparatus, and a controller configured to, when a video signal and an audio signal are received, transmit an audio signal return request to the display apparatus along with the video signal and the audio signal, when the audio signal is returned from the display apparatus, calculate an output time difference of the video signal and the audio signal based on a return timing of the audio signal, delay the audio signal according to the output time difference and transmit the audio signal to the audio signal output apparatus.

A/V receiving apparatus and method for delaying output of audio signal and A/V signal processing system

A digital interface system to display an inappropriate connection state of a digital interface (High-Definition Multimedia Interface (HDMI) in an HDMI connection supporting an Ethernet function and a cable connection state displaying method therefore. When a user intends to use the Ethernet function by connecting the HDMI cable, the inappropriate connection of the HDMI cable is displayed on a screen by a message or a diagram. Also, in case of a plurality of connected HDMI cables, the position of an inappropriate HDMI I cable is indicated on the screen. Even though it is difficult to distinguish a general HDMI cable from an HDMI with HDMI Ethernet and Audio Return Channel (HEAC) cable, an inappropriate HDMI cable connection is accurately identified.

Digital interface system to support Ethernet and cable connection state displaying method thereof

PURPOSE: An HDMI(High Definition Multimedia Interface) system supporting an Ethernet function, and a method for displaying HDMI cable connection condition of the same are provided to allow a user to confirm the connection state of an improper HDMI cable which supports an Ethernet function. CONSTITUTION: An HDMI system comprises a source device(100), and the source device includes a decoder(110), an HDMI transmission unit(120), a control unit(130), an Ethernet communication unit(140), and a signal detection unit(150). The decoder decodes and outputs a digital A/V signal transferred from a disk or broadcasting signal. The HDMI transmission unit transmits the decoded digital A/V data in signal format proper to a digital interface of the HDMI. The control unit reads out the data format information for recognizing an image device(200) through a DDC(Display Data Channel)/CEC(Consumer Electronics Control) line in the connection with the HDMI cable. The Ethernet communication unit performs Ethernet communication with the image device through the HDMI cable, and the signal detection unit judges whether or not a square wave signal is detected.
