    Abstract: A method is provided for transmitting an Application Layer-Forward Error Correction (AL-FEC) packet by an AL-FEC packet transmission apparatus in a multimedia communication system. AL-FEC packets are generated. The AL-FEC packets are transmitted to an AL-FEC packet reception apparatus. Each of the AL-FEC packets includes an AL-FEC codeword symbol and an AL-FEC header, and the AL-FEC codeword symbol is one of AL-FEC codeword symbols included in an AL-FEC codeword block. The AL-FEC header includes order information indicating an order of an AL-FEC codeword symbol into which the AL-FEC header is inserted among the AL-FEC codeword symbols included in the AL-FEC codeword block.

    Abstract: Methods and apparatuses are provided for reducing a Peak to Average Power Ratio (PAPR) in a digital broadcasting system. Reserved tones are determined in previously determined locations of sub-carriers that do not collide with a pilot signal of a preamble in a frame. A signal is transmitted through the reserved tones in a period for which the preamble is transmitted. If a Fast Fourier Transform (FFT) size is 8K, locations of the reserved tones are determined in accordance with a specified chart.

    Abstract: A method for transmitting a packet by a signal transmission apparatus in a broadcasting and communication system is provided. The method includes generating a Forward Error Correction (FEC) packet including an FEC parity packet and an FEC source packet by encoding source payloads using an FEC encoding scheme, and transmitting the FEC packet to a signal reception apparatus, wherein the FEC parity packet is generated using a plurality of Source Sub-Blocks (SSBs) which are generated using specific source payloads selected corresponding to a preset SSB generation scheme from among the source payloads included in a source block, and wherein the FEC source packet is generated using the source payloads.

    Abstract: An apparatus to detect coordinates in a pen-based display device is provided. When an electronic pen is placed at a specific position on a display, an image of a pixel group corresponding to a specific position is captured through a camera, a reference point is detected in the pixel group by processing the captured image of the pixel group, values of a plurality of coordinate indications and a plurality of parity indications, it is determined whether an error has been detected by calculating a predetermined error detection formula using the determined values of the coordinate indications and the parity indications, and final coordinates of the electronic pen are determined by applying a predetermined coordinates calculation rule to the determined values of the coordinate indications and the parity indications, if no error has been detected in the determined values of the coordinate indications and the parity indications.
