The Symbol View shows more detailed information for the current cursor position within the Time View. Given the communication scheme used by 1394, a series of different encoded and scrambled characters on the bus may actually be a single descrambled and decoded symbol value that is being repeated. Because of this the Symbol View simply combines those characters into one item and displays how many times the symbol was repeated (Symbol Count). It also shows the symbol in different forms: hexadecimal value, the symbol name and the first 10b scrambled and coded character value in the series.
If the current cursor position points to a point in time where it is impossible to decode the raw bit stream then the Symbol View will show the RAW bit data as it occurred on the bus.
