| 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 |
| 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 |
| 20100138439 | DISPLAY APPARATUS AND DISPLAY METHOD - A display apparatus includes: a first communication unit which conducts communication with an external device connected to the first communication unit; a second communication unit which conducts communication with a contents provider server; a display unit which displays contents being reproduced by the external device and contents related information; and a controller which controls the first communication unit to acquire contents reference information from the external device and controls the second communication unit to retrieve the contents related information using the contents reference information. | 06-03-2010 |
