Video data processing apparatus and file management method

A video data processing apparatus configured to receive a data file through a network, the video data processing apparatus comprising:

• a file receiving module connected to the network, and configured to receive the data file comprising a header through the network, the header comprising a header key field, a header length field, and a header value field in a first repetition order, the header key field indicative of a data type of header metadata information in the following header value field, the header length field indicative of a data length of the header value field, the header value field comprising the header metadata information;
• an analyzer configured to detect a character string indicative of a head of the header key field, to detect the header key field of the received data file, and to read out header metadata information from a following header value field, based on the data type in the header key field, and a data length in the header length field following the header key field;
• a default data storage module configured to store default data;
• a data restoration module configured to discard header data from a first position, in absence of the character string at the first position, and to restore the default data instead of the discarded header data from the first position to a next header key field;
• and
• a management module configured to store the read header metadata information, and the restored default data.
