| 20090034531 | Host device interfacing with a point of deployment (POD) and a method of processing broadcast data - A host device interfacing with a point of deployment (POD) and method of processing broadcasting data are disclosed. An IP physical interface unit receives a frame including an internet protocol (IP) packet carrying broadcast data through a network modem. A routing engine routs the frame based on a destination information included in the frame. An IP to TS Decapsulator extracts a MPEG-2 TS packet from the IP packet included in the routed frame. And a multiplexer augments the extracted MPEG-2 TS packet with Packet Header carrying an identification information, multiplexes the augmented MPEG-2 TS packet and forwards the multiplexed MPEG-2 TS to the POD. | 02-05-2009 |
| 20090055544 | Broadcasting receiver and method of interfacing resource information between a host device and a POD, sending host device resource information and obtaining host device resource information - A broadcasting receiver and method of interfacing resource information between a host device and a POD, sending host device resource information and obtaining host device resource information are disclosed. A POD sends a resource information requesting message. And a host device receives the resource information requesting message and responds with a resource information message including a resource identifier defined in a resource information table which includes information indicating whether the host device supports A-mode. Using a “conditional access” feature provided by a conventional cable security card, content received through any type of transport protocol (including an IP protocol) including a wired/wireless network can be protected and A-mode resource information can be systematically defined together with other-mode IP communication resource and the resource information of different modes can be integrated and transmitted to the host device. | 02-26-2009 |
| 20090079942 | Automatic Vision Display Apparatus Using Pursuit of Flying Path of Flying Screen Unit - An automatic vision display apparatus has a flight object having a floating gas filled therein to fly, flying along a vertical wall surface and including a screen mounted at an opposite side to the vertical wall surface; a propulsion unit mounted at a predetermined position of the flight object and moving the flight object; a control unit mounted to the flight object and controlling the propulsion unit; a projector projecting an image on the screen of the flight object at a distance from the flight object; an adjusting unit adjusting an image projecting direction of the projector; and a main control unit controlling the projector to project the image and controlling the adjusting unit so that the projector tracks a movement of the flight object to project an image. According to the invention, it is possible to project an image while automatically tracking the screen of the flight object being flying. In addition, it is possible to correct a distortion of the projected when the screen of the flight object consists of the three dimensional curved surface. | 03-26-2009 |
| 20110138164 | DIGITAL BROADCAST RECEIVER AND BOOTING METHOD OF DIGITAL BROADCAST RECEIVER - A digital broadcast receiver and a booting method of the digital broadcast receiver are disclosed herein. A method of secure booting of a system in a digital broadcast receiver comprises aligning a plurality of interleaved portions to generate a digital signature, respectively, with an entire firmware image, generating a digital signature of each interleaved portion, selecting a specific interleaved portion, generating a first message digest to read a region of the selected interleaved portion in the entire firmware image and a second message digest from the digital signature of the selected interleaved portion and verifying the firmware image based on the first and second message digest and booting the system in the digital broadcast receiver. | 06-09-2011 |
| 20120066710 | BROADCASTING RECEIVER AND METHOD OF INTERFACING RESOURCE INFORMATION BETWEEN A HOST DEVICE AND A POD, SENDING HOST DEVICE RESOURCE INFORMATION AND OBTAINING HOST DEVICE RESOURCE INFORMATION - A broadcasting receiver and method of interfacing resource information between a host device and a POD, sending host device resource information and obtaining host device resource information are disclosed. A POD sends a resource information requesting message. And a host device receives the resource information requesting message and responds with a resource information message including a resource identifier defined in a resource information table which includes information indicating whether the host device supports A-mode. Using a “conditional access” feature provided by a conventional cable security card, content received through any type of transport protocol (including an IP protocol) including a wired/wireless network can be protected and A-mode resource information can be systematically defined together with other-mode IP communication resource and the resource information of different modes can be integrated and transmitted to the host device. | 03-15-2012 |
