    Abstract: This disclosure relates to a 5G or pre-5G communication system for supporting a higher data transfer rate than a 4G communication system such as LTE. The present invention relates to a method for encoding and decoding a channel in a communication or broadcasting system, comprising the steps of: determining an input bit size (CBS); determining a code rate (R); determining a size (Z) of a block; comparing the determined CBS and code rate with predetermined reference values; determining an LDPC sequence to perform LDPC encoding according to the comparison result; and performing LDPC encoding and decoding on the basis of the LDPC sequence and the block size. Further, the present invention comprises the steps of: determining a code rate (R) indicated by a modulation and coding scheme (MCS) index; determining a transport block size; and determining either a first basic matrix or a second basic matrix as a basic matrix on the basis of the transport block size and the code rate.

    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.

    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.
