Abstract:
The present invention relates to a method and apparatus of calculating a location of an electronic device. The present invention comprises receiving a common packet from a host device, wherein the common packet includes at least one of time information or frequency related information through which a data packet is transmitted; receiving the data packet based on information included in the common packet from the host device, wherein the data packet includes at least one of a location related information, or antenna related information of the host device; obtaining angle information indicating a location relation with the host device using at least one of the location related information or the antenna related information included in the received data packet; and calculating the location of the electronic device based on the angle information.
Abstract:
A method for Internet Protocol Television (IPTV) service discovery and an IPTV receiver using the same are provided. The method for IPTV service discovery includes collecting system provider discovery information (SP discovery information), and collecting service discovery information by using the collected SP discovery information, wherein the SP discovery information includes target package information regarding a segment obtained by dividing the service discovery information.
Abstract:
Provided are a video display device and a method of operating the same. The method includes: executing an enhanced service playing application not dependent on any single channel; obtaining an uncompressed audio video (AV) content; playing the uncompressed AV content through the display unit; attempting to obtain contents information on the uncompressed AV content on the basis of a part of the uncompressed AV content; transmitting an enhanced service request message to an enhanced service providing server not dependent on any single channel by the enhanced service; receiving an enhanced service from the enhanced service providing server; and playing the enhanced service through the display unit by the enhanced service playing application.
Abstract:
A plasma display panel and a plasma display apparatus are disclosed. The plasma display panel includes a front substrate on which a scan electrode and a sustain electrode are positioned parallel to each other, an upper dielectric layer positioned on the scan and sustain electrodes, a rear substrate on which an address electrode is positioned to intersect the scan and sustain electrodes, a lower dielectric layer positioned on the address electrode, a barrier rib that is positioned between the front substrate and the rear substrate and partitions a discharge eel, and a phosphor layer that is positioned inside the discharge cell and includes YVPO 4 :Eu. The scan electrode and the sustain electrode each having a single-layered structure.
Abstract:
A method of processing an interactive service and an apparatus thereof are disclosed. The present invention includes sending a discovery message to a second screen application running in a second device, wherein the discovery message advertises second screen support services that the first device can provide, receiving a request for descriptions of the second screen support services from the second screen application, sending a response with the descriptions to the second screen application, providing a HTTP proxy server using a HTTP proxy server service allowing the second device to access files that are received by the first device in a broadcast stream, wherein the HTTP proxy server service is one of the second screen support services, receiving the files from the broadcast stream and delivering the files to the second device via the HTTP proxy server.
Abstract:
A purchase transaction method for IPTV product and IPTV receiver thereof using the same are provided. The purchase transaction method for IPTV product includes requesting to make a purchase for a offering by using a identifier of the offering, wherein the offering is a combination of one or more products to be purchased and purchase terms for the products; and obtaining a response returned from the request to indicate success or failure of the requested purchase.
Abstract:
A plasma display panel is disclosed. The plasma display panel includes a scan electrode and a sustain electrode positioned parallel to each other on a front substrate, an upper dielectric layer positioned on the scan electrode and the sustain electrode, a rear substrate on which an address electrode is positioned to intersect the scan electrode and the sustain electrode, a lower dielectric layer positioned on the address electrode, and a barrier rib positioned between the front substrate and the rear substrate. The barrier rib includes lead (Pb) equal to or less than 1,000 ppm (parts per million). A discharge gas is filled between the front substrate and the rear substrate and includes helium (He) of 9% to 42%.
Abstract:
Disclosed herein are a photovoltaic module and a photovoltaic system including the photovoltaic module. The photovoltaic module includes a solar cell module having a plurality of solar cells, an inverter to convert DC power from the solar cell module to AC power, a cable to output the AC power from the inverter, and an infrared (IR) communication unit to transmit, at least one of voltage information of the solar cell module, current information of the solar cell module, voltage information of the inverter, and current information of the inverter, to an adjacent first photovoltaic module, an external gateway, or an external IR communication device. Thereby, communication with an external terminal can be easily performed.
Abstract:
A video display apparatus pairs with a first terminal device. The video display apparatus receives an audio-visual content, and displays the audio-visual content. The video display apparatus acquires enhanced service information on an available enhanced service for the audio-visual content, and notifys an occurrence of the available enhanced service to the first terminal device.
Abstract:
