KEB File Format

Binary File Format: B8

The envelope data for each channel can be recorded in a binary data file for use by post_processing software.  Every ping cycle, one record (see Table 3-2) is stored with header information and raw data for each frequency channel.  Each record is variable in length with a current maximum possible number of 6656 bytes, and can be compressed using a Huffman compression algorithm. The storage device for these files should have sufficient disk space free to store the vast amounts of data generated, especially when working in shallow water where the faster ping rate results in a larger volume of data being generated.

The binary data files are recorded using the following basic structural format:

File Type Id Preamble (40 bytes)

Data Records

The recording program will write data records to one file for up to 20000 pings, then the current file will be closed and a new one will be opened for subsequent data recording.

File Type Id Preamble

The first 40 bytes of the file are used for a file type identification preamble for the playback software to use to determine if the file is in the valid format supported by the version of software being used.

Example:

KEB D409-03167 V1.00 Huffman

(pad unused character locations with spaces)

where,	KEB identifies the file as a KEL Binary file,

D409-03167 identifies the part number of the program used to record/convert the data,

V1.00 identifies the version of the program used to record/convert the data.

Huffman indicates that the data is in a compressed format (not present for uncompressed files)

After the File Type Id Preamble, the actual data records are stored as they are received. As soon as a record is received, it is recorded to the disk file.  Records are recorded to the file in the same order as they were received (time stamps must be in sequential order).  Multiple types of records can be stored in the binary file; ie Envelope data records, serial port sensor data records, configuration records, etc  (only Envelope records are actually implemented at this time).  The original data record format is shown in Table 3-2.  The data can be stored in this format, or the user can enable data compression.  When compression is enabled, each data record as shown in Table 3-2 has a Huffman compression algorithm applied to it.  The result of the compression is stored in the file.  The playback application runs the matching decompression algorithm to access the data records.


Record Preamble

Each data record is preceded by a Record Preamble that provides quick access, particularly for compressed records, to useful info about the record.  This data is used by the PostSurvey application for faster analysis of the data statistics.  See the following description about the Data Records for some of the field definitions.

The SPM Frequency code is the frequency identification code number read from the actual SPM hardware.  For the HF channel, the raw 8-bit hex code is used.  For the LF channel, the 8-bit hex code is bit-wise “or’ed” with 080h (MSB set to one); this enables the Echo Control and Post Survey applications to distinguish which channel has been recorded when an echosounder is only using one channel for data acquisition.  The echosounder only sends the envelope data for the active channel and the Echo Control program only records the one channel; this saves on data transfer times and disk space requirements for the data recording

Event marks can be initiated from a number of sources; the Event Mark code indicates the source of the event mark as described in Table 3-4.  Serial Port and Hypack initiated event marks often have variable-length annotation strings recorded as well.
