XDS Codec Filter

This topic applies to Windows XP Service Pack 1 or later.

The XDS Codec filter supports third-party software that decodes TV ratings information from the extended data services (XDS) channel of line 21.

This filter receives XDS data from the CC Decoder filter or some other source. It passes this data to the XDSToRat object, which is responsible for parsing the data into content ratings. The XDSToRat object returns the decoded ratings to the XDS Codec filter.
