The method includes generating an LDPC code based on a resulting parity check matrix which is generated by performing a row splitting operation on a base parity check matrix; and transmitting the LDPC code. The row splitting operation includes splitting each row block included in the base parity check matrix into row blocks, a number of the row blocks is determined based on a splitting factor, and the splitting factor is determined based on a number of repair symbols included in a repair symbol block of the base parity check matrix, a number of rows included in the base parity check matrix, and a scaling factor for determining a size of each permutation matrix in the resulting parity check matrix and a size of each zero matrix included in the resulting parity check matrix."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for transmitting and receiving a quasi-cyclic low density parity check code in a multimedia communication system","description":"A method and apparatus are provided for transmitting an LDPC code in a multimedia system.
