Method and system for supporting random access of mpeg data

A method of performing a random access of MPEG data, the method comprising:

• receiving at least one media processing unit (MPU);
• extracting an initialization flag included in a header of the at least one MPU;
• determining whether the at least one access unit included in the at least one MPU comprises all of data required for initialization of a decoding process, based on the initialization flag;
• and
• activating a random access to the at least one access unit included in the at least one MPU, based on the determination result.

A method of supporting a random access of MPEG data, the method comprising:

• obtaining at least one access unit comprising media data coded through processing comprising an encapsulation and a packetization;
• generating at least one media fragment unit (MFU) by fragmenting the at least one access unit;
• determining an initialization data flag indicating whether the at least one MFU comprises all of data required for initialization of a decoding process, in the at least one MFU;
• and
• inserting the initialization data flag into a header of the at least one MFU.

A method of performing a random access of MPEG data, the method comprising:

• receiving at least one media fragment unit (MFU);
• extracting an initialization data flag included in a header of the at least one MFU;
• determining whether the at least one MFU comprises data used for initialization of a decoding process, based on the initialization data flag;
• and
• activating a random access to the at least one MFU based on the determination result.
