System and method for representing compressed information
First Claim
1. A method for transmitting data in a bitstream having a plurality of frame portions, the bitstream obeying the ISO/IEC 13818-7, Advanced Audio Coding protocol or the ISO/IEC 14496-3 protocol that permits the transmission of private data in the DES field of the obeyed protocol, the method comprising:
- receiving data from a data source;
determining syntax information for the data;
encoding the data and the syntax information into an encoded bitstream, at least a portion of the syntax information being included in the DES field and the interpretation of said portion of the syntax information being unspecified by the obeyed protocol; and
transmitting the encoded bitstream.

Abstract
The present invention provides a system and method for storing re-synchronization, error correction and/or error detection data within an existing communication protocol, while still maintaining full compliance to a standard, such as the MPEG-2 AAC standard. By doing so, data information can still be passed from an encoder to a decoder via a channel using an existing and well known standard transport protocol. However, the existing well known transport protocol can now include the data necessary for synchronization of the decoder to the received raw data, along with error detection and error correction by the decoder.

14. An apparatus that transmits data in a bitstream having a plurality of frame portions, the bitstream obeying the ISO/IEC 13818-7, Advanced Audio Coding protocol or the ISO/IEC 14496-3 protocol that permits the transmission of private data in a private data portion, the apparatus comprising:
a transmitter that receives data from a data source, determines syntax information for the data, encodes the data and the syntax information into an encoded bitstream, at least a portion of the syntax information being included in the private data portion of the encoded bitstream, and transmits the encoded bitstream, the interpretation of said portion of the syntax information being unspecified by the obeyed protocol. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A method comprising:
-
receiving a bitstream having a plurality of frame portions, the bitstream obeying the ISO/IEC 13818-7, Advanced Audio Coding protocol or the ISO/IEC 14496-3 protocol that permits the transmission of private data in a private data portion, the interpretation of at least a portion of the data in the private data portion being unspecified by obeyed protocol, the bitstream including encoded data and further including syntax information for the encoded data, at least a portion of the syntax information being included in the private data portion; and
obtaining said portion of the syntax information from said private data portion. - View Dependent Claims (28, 29)
