A large number of unique and proprietary data structures has been developed for specific data recording applications that required unique decoding software programs. The activities of writing unique decoding software, checking the software for accuracy, and decoding the data formats are extremely time-consuming and costly. Specifically, this packet format standard shall be usable with multiplexing of both synchronous and asynchronous digital inputs such as pulse code modulation PCM Military Standard MIL-STD 1553 data bus, time, analog, video Aeronautical Radio, Inc. ARINC 429 discrete and Universal Asynchronous Receiver and Transmitter UART containing Recommended Standard RS-232422485 communication data. This packet standard will allow use of a common set of data interpretation libraries to reduce the cost of producing data analysis systems. Within this standard, where text, figures, or tables are used to provide descriptions, meaning, andor explanations, the text shall take precedence over figures and tables. The data format structures packet header, secondary packet header, channel-specific data word, intra-packet data header, and packet trailer described in Section 11.2 are defined to have the following bit and byte orientation. The least significant byte shall be transmitted first the least significant bit of each byte shall be transmitted first, with most significant bit transmitted last and data is read from the lowest logical address first. This ordering is commonly referred to as Little Endian. The packet data shall remain in its native byte order format.
