| 20080266455 | INACTIVE INFORMATION PROVIDING METHOD AND VIDEO APPARATUS THEREOF - An inactive information providing method of a video apparatus includes, in an inactive mode, generating an inactive message which provides notification of the inactive mode; and transmitting the inactive message to an external device connected according to a High Definition Multimedia Interface (HDMI) Consumer Electronics Control (CEC) specification. | 10-30-2008 |
| 20080270632 | METHOD FOR MANAGING LOGICAL ADDRESS AND DEVICE THEREOF - An address management method and a device thereof are provided. The address management method includes checking by a device whether logical addresses are currently being used by external devices; and setting by the device a non-use logical address as a logical address of the device regardless of the type of the device, if the device determines that the non-use logical address exists. Therefore, a device may use all logical addresses regardless of its device type, and may also have a logical address even though all logical addresses corresponding to its device type are currently being used. | 10-30-2008 |
| 20080270636 | METHOD FOR MANAGING LOGICAL ADDRESS AND DEVICE THEREOF - An address management method and a device thereof are provided. The address management method includes determining by a device whether all logical addresses corresponding to a type of the device are currently being used by external devices; setting by the device a non-use logical address as a logical address of the device, if it is determined that one of the logical addresses is currently not in use; and setting by the device a predetermined logical address as a logical address of the device, if it is determined that all the logical addresses are currently being used. Therefore, logical addresses may be allocated to a device even if all logical addresses corresponding the type of the device are currently being used. | 10-30-2008 |
| 20080271073 | METHOD OF PROVIDING KEY CODE INFORMATION AND VIDEO DEVICE THEREOF - A method of providing key code information of an external device and a video device thereof are provided. The method of providing key code information includes transmitting a message for requesting supportable key code information of a connected external device, and receiving a response message regarding the supportable key code information from the external device in response to the request message. Accordingly, the video device can provide the key code information supported by the external device to a user. | 10-30-2008 |
| 20080271074 | METHOD FOR PROVIDING SERVICE INFORMATION AND APPARATUS THEREOF - A method for providing service information and a video apparatus employing the same are provided. The method for providing service information includes transmitting a request message for service information provided by an external apparatus connected according to the High Definition Multimedia Interface Consumer Electronics Control (HDMI CEC) standard, and receiving a reply message for the service information from the external apparatus as a reply to the request message. Accordingly, the video apparatus provides service information provided by the external apparatus connected thereto to a user. | 10-30-2008 |
| 20080281995 | ADDRESS MANAGEMENT METHOD AND VIDEO APPARATUS USING THE SAME - An address management method and a video apparatus using the same are provided. The address management method includes determining whether an external device is connected or not; when determining the connection to the external device, generating an invalidation message for invalidating an address; and transmitting the generated invalidation message to the external device. Accordingly, when the port connection is changed, the physical address can be correctly updated by invalidating the former physical address. | 11-13-2008 |
| 20080291324 | PACKET GENERATING METHOD IN WIRELESS HDMI CEC - A packet generating method in a wireless High Definition Multimedia Interface (HDMI) environment includes generating a packet which includes either AV data or control data in a payload and a field indicative of a packet type in a header according to a HDMI environment; and transmitting the generated packet. Accordingly, the AV data and the control data can be transceived over the single channel in the HDMI. | 11-27-2008 |
| 20090013366 | METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DATA GENERATED ON APPLICATION ACCORDING TO HDMI CEC - A method and apparatus for transmitting and receiving data generated on an application according to the High Definition Media Interface Consumer Electronics Control (HDMI CEC) standard are provided. The method and apparatus enable transmission and reception of audio, video and control signals through CEC of an integrated HDMI cable, without using a complicated TCP/IP structure. As a result, wiring is simple and Audio/Video (AV) devices are used dynamically. | 01-08-2009 |
| 20090147137 | METHOD FOR PROVIDING INFORMATION ON TYPE OF IMAGE APPARATUS AND IMAGE APPARATUS ADOPTING THE SAME - A method for providing information on types of image apparatus being used and an image apparatus adopting the same are provided. The method for providing information on the types of image apparatus being used includes transmitting a request message to external devices inquiring whether or not the external device which is connected using a high definition multimedia interface consumer electronics control (HDMI CEC) standard is a device of a particular type, and receiving from the external devices a response message answering whether or not the external device is a device of the particular type, in response to the request message. Accordingly, information on the type of connected external devices is obtained, and a list of external devices or a menu of external devices is provided according to the obtained type to the user so that the user can use the image apparatus more conveniently. | 06-11-2009 |
| 20100079494 | DISPLAY SYSTEM HAVING DISPLAY APPARATUS AND EXTERNAL INPUT APPARATUS, AND METHOD OF CONTROLLING THE SAME - A display system having a display apparatus and an external input apparatus, and a method of controlling the same. In the method an image is displayed on a display apparatus. A phase shift of an external input apparatus is detected. The detected phase shift is transmitted to the display apparatus, and the image displayed on the display apparatus is rotated based on the detected phase shift. | 04-01-2010 |
| 20100079672 | DISPLAY APPARATUS CAPABLE OF MOVING IMAGE AND CONTROL METHOD THEREOF - A display apparatus capable of moving an image and a control method thereof are provided. The display apparatus includes a display unit, an interface which receives image coordinate information and image source information from an external device that displays the image, and a controller which controls the display unit to display the image using the image coordinate information and image source information. Therefore, the image can continue to move between display apparatuses while being displayed, thereby increasing user convenience. | 04-01-2010 |
