    摘要： 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.

    摘要： Various embodiments of the present disclosure propose an apparatus and method for supporting a service for one program through a channel change in a digital broadcasting system. To this end, a broadcast providing device may monitor whether a channel switching event occurs while providing a service for a first program on a first channel on the basis of a predetermined broadcast program schedule. When the channel switching event occurs, before the service for the first program on the first channel ends according to the predetermined broadcast program schedule, the broadcast providing device may transmit, to a broadcast consumer device, connection control information required to continue the service for the first program on a second channel. The broadcast consumer device may perform service switching on the basis of the connection control information.

    摘要： A method for transmitting a packet for N data streams in a communication system is provided. The method includes dividing each of the data streams into data payloads and adding a header for discriminating between the N data streams to each of the data payloads, determining, from the source packet flow, an FEC source formed by source packets generated from an (N−M) number of data streams, distinguishing at least one source packet block, generating a source symbol block from the at least one distinguished source packet block, generating a repair symbol block formed by at least one repair symbol, determining a repair flow ID for identifying a repair flow formed by the repair symbols generated from the FEC source packet flow, generating an FEC repair packet by adding a header to each of the repair symbols of the repair flow, and transmitting the source packet and the FEC repair packet.

    摘要： 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.

    摘要： 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.
