4 TMUX recording format 1 Purpose Each recording begin obligatorily with an information block called "Secretariat". This block consists of a heading and data, intended to indicate to the user the contents of the recording which will follow (number of channels, number of cards, start time...). The heading, commune with all the blocks, makes it possible to know the origin of the data thanks to the CH which indicates the channel number. In the case of "Secretariat", a specific number is allotted (CH=300 hexadecimal). Each tape record ends by end code who results in a modification of the channels number in the heading of each channel. A specific stop number is then positioned in the field indicating the end of the recording thus. (CH=30F hexadecimal). Any record is thus composed of a block "Secretariat" (CH=300 hexadecimal) followed data to be recorded, then a series of channels including the end code. A block "USER S INFORMATIONS" (CH=301 hexadecimal) follows the block "Secretariat": it contains the properties channels: name of the channel, parameters A X +B and units. A block "CARS CALIBRATION" (CH=302 or 306 hexadecimal) could be inserted between the block "USER S INFORMATION and the first data block. It will contain ASCII fields describing the gain and the offset to be applied to each channel to obtain a better measurement. A block " SENSORS CALIBRATION" (CH=305 hexadecimal) could be inserted between the block «CARS CALIBRATION» and the first data block. It will contain ASCII fields describing the gain and the offset to be applied to each channel to obtain a physical measure. The data of each channel are organized in block. Each block contains a heading and data of a channel. The blocks are generated at fixed intervals and have an unspecified size. There is no constraint on the appearance order of the blocks of each channel. Filling words can be inserted between the blocks. This filling obligatorily consists of a whole number of bytes. The blocks are organized in 32-bits words. The heading consists of bits words. The samples are grouped in 32-bits words and are arranged in the order of acquisition. The first received sample is in the strong weight of the first data word of the block. The last sample is in the last word. This last word of the block is not complete if the total number of received samples does not form a whole number of words of 32-bits. The weak bits of weight of this last word are then not indicated, their value is indifferent.. Empty blocks not containing that a heading can be recorded.

22 7.8.2 JPEG2000 compliant header etailed information about JPEG2000 markers can be found in the ISO/IEC standard. The JPEG2000 compliant header contains main and tile headers from the JPEG2000 standard. It consists of all the parameters needed to decode an image correctly, including the quantization step sizes. The table below lists the most common markers that are inserted into the compressed code stream by the board.
