Abstract
In an IPTV network, a program content stream is processed to create an artifact detectable by a commercial remover in a program content portion of the program content stream. The artifact may be created by splicing first and second portions of program content together such that the artifact appears in the program content. A commercial remover processing the resultant program content stream erroneously removes portions of program content or leaves portions containing commercial content in the program content stream.
