Synchronization method and apparatus of moving picture experts group transport stream for reducing initial delay

An apparatus for synchronization of a moving picture experts group (MPEG) transport stream, which minimizes a delay of an initial synchronization, the apparatus comprising:

• a code word register for storing predetermined code words;
• a first comparator for comparing a bit difference between the sync words and the code words with a threshold value, the first comparator operating when a mode register comprises a value of “0”;
• a second comparator for comparing all bits of the sync words with all bits of the code words, the second comparator operating when a mode register comprises a value of “0”;
• and
• the mode register comprising a value of “1” when all bits of the sync words correspond to all bits of the code words as a result of the comparison by the second comparator,
• wherein the MPEG transport stream is descrambled when a determination is made as a result of the determination that the bit difference is less than to the threshold value or the mode of the packet synchronization unit is set to “1”.

A non-transitory computer-readable medium having embodied thereon a computer program for executing a method for synchronization of a moving picture experts group (MPEG) transport stream, which minimizes a delay of an initial synchronization, the method comprising:

• comparing sync words indicating a start point of the MPEG transport stream with predetermined code words;
• determining, as a result of the comparison, whether a bit difference between the sync words and the code words is less than a threshold value when a mode of a packet synchronization unit is set to “0”;
• verifying if all bits of the sync words correspond to all bits of the code words, when a determination is made as a result of the determination that the bit difference is less than or equal to the threshold value;
• setting the mode of a packet synchronization unit to “1”, when a determination is made as a result of the determination that the all bits of the sync words is equal to the all bits of the code words;
• and
• descrambling the MPEG transport stream when a determination is made or the mode of the packet synchronization unit is set to “1”.
