bslbf [MPEG-2 Semantics]
bit string, left bit first.
"Left" is the order in which bit strings are written and are shown as a string of 1s and 0s within single quote marks. When there are blanks within the quote marks, these are merely for ease of reading and have no significance
This is the mnemonic used in MPEG-2 private table sections to represent 'not-quite-numeric' values such as boolean fields, pointers and variable-length fields such as data_byte. For numeric values the uimsbf mnemonic is generally used.
Examples
The continuity_counter field in an MPEG-2 transport packet is a purely numeric value that ranges from 0 to 15. It is indicated as a uimsbf field.
The adaptation_field_control field in an MPEG-2 transport packet is used to signal the presence (or lack of same) of an adaptation field in a transport packet. This field is designated as bslbf.
