Abstract:
1. A method of storing program data, which is encoded by compression, comprising: extracting information related to a desired program, which is to be referenced in reproducing the program data of the desired program, from the program data, the extracted information including information associated with an I-picture that is extracted by: making a table of the extracted information, the table including only information to be referenced in reproducing the program data of the desired program at variable speed; and storing the table having the extracted information with the program data of the desired program in a storage apparatus, wherein the program data is encoded by compression according to the MPEG-2 standard and packetized as packets in the form of the TS, wherein the extracting of the information comprises extracting a program allocation table (PAT), a program map table (PMT), location information of the I-picture, and description information of each packet, and wherein the program data of the desired program is reproduced by referring to the extracted information stored in the table.
