| 20080215872 | METHOD OF BOOTING ELECTRONIC DEVICE AND METHOD OF AUTHENTICATING BOOT OF ELECTRONIC DEVICE - Provided is a method of booting an electronic device including a host central processing unit (CPU) and a security module. The method includes: the host CPU starting to boot a system by using boot information in response to a reset or power on event of the electronic device; and when an authentication start instruction is not received by the security module from the host CPU until a first predetermined period elapses after an occurrence of the reset or power on event of the electronic device, controlling an operation of the host CPU by the security module. According to the method, when the authentication start instruction is received before the first predetermined period elapses, the security module authenticates the boot information and controls the operation of the host CPU based on an authentication result. A method of authenticating a boot of the electronic device in the security module is also provided. | 09-04-2008 |
| 20080240256 | METHOD AND APPARATUS FOR DISPLAYING VIDEO DATA - Provided is a method and apparatus for displaying video data without a display delay. In the method, a code indicating an end of stream is appended so that the code is appended behind a last video stream included in a stream to be displayed when only a part of an input stream including one or more video streams is displayed. In addition, the last video stream is displayed which is appended with the code indicating an end of stream. | 10-02-2008 |
| 20090034559 | VIDEO APPARATUS HAVING PVR FUNCTION AND CONTROL METHOD THEREOF - A video apparatus having a personal video recorder (PVR) function and a control method thereof are provided. The video apparatus includes a counter which assigns a timestamp to a transport stream packet, a synchronization unit which extracts time information from the transport stream packet, compares the extracted time information with system time information of the video apparatus, and outputs synchronization control information, and a controller which stores an information table created using the timestamp and synchronization control information. | 02-05-2009 |
| 20090064261 | METHOD FOR PROVIDING USER INFORMATION AND BROADCAST RECEIVING APPARATUS USING THE SAME - A broadcast receiving apparatus and a method for providing user information are provided. The broadcast receiving apparatus transmits user information stored in a storage medium to a broadcast station. Therefore, a user may participate in data broadcasting more conveniently. | 03-05-2009 |
| 20100129060 | DIGITAL BROADCAST RECEIVING APPARATUS AND METHOD - A digital broadcast receiving apparatus and a digital broadcast receiving method are provided. An oscillator changes a reference frequency of a system clock of the digital broadcast receiving apparatus using a PCR | 05-27-2010 |

| 20090033804 | METHOD FOR FORMATTING DIGITAL BROADCAST TRANSPORT STREAM PACKET FOR IMPROVED RECEIVING PERFORMANCE, DIGITAL BROADCAST TRANSMITTER, AND SIGNAL PROCESSING METHOD THEREOF - A method of formatting a digital broadcast transport stream packet, a digital broadcast transmitter, and a signal processing method thereof, includes constructing a transport stream packet that includes a stuffing region for an insertion of a known supplementary reference signal (SRS) data therein, randomizing the packet that includes the stuffing region is randomized, and the SRS data is inserted into the stuffing region of the randomized packet. Adding a parity for an error correction to the packet into which the SRS data has been inserted, the packet to which the parity has been added is interleaved, and a trellis encoding of the interleaved packet is performed. Inserting a segment sync signal and a field sync signal into the trellis-encoded packet, and a vestigial side band (VSB) modulation and an RF conversion of the packet are performed to transmit the VSB-modulated and RF-converted packet. | 02-05-2009 |
