Parameter data coding method for conditional-access-system encodes parameter value using multi-digit number for parameter range to provide bit word

摘要

The coding method has at least 2 value ranges for the parameter value defined, each value range having a given multi-digit number, with the parameter value encoded to provide a bit word using the multi-digit number of the range in which it lies, before combining with a second bit word identifying the value range, to provide a codeword. - Also included are Independent claims for the following: - (a) a parameter data coding device; - (b) a coded data decoding method; - (c) a coded data decoding device
