I think we can't do much here unless we have more information. Thus I'm closing the report.
If you still think there is a problem, please re-open and state why you think the problem is there.
Note: See TracTickets for help on using tickets.
Why do you think it is wrong?
It looks correct to me. Cost equal to 0 refers to the case that all transform coefficient levels are equal to 0. The costs calculated in the encoding process are cost differences relative to this default case. Hence, if all costs of the trellis paths are greater than 0, the default (all levels equal to 0) is chosen, in which case nothing needs to be modified.
