Abstract: Various implementations process a television content stream to detect program boundaries such as the starting point and ending point of the program. In at least some implementations, program boundaries such as intermediate points between the starting point and ending point of the program are also detected. The intermediate points correspond to where a program pauses for secondary content such as an advertisement or advertisements, and then resumes once the secondary content has run. Once program boundaries are detected, primary content is isolated by removing secondary content that occurs before the starting point and after the ending point. In at least some implementations, secondary content that occurs between detected intermediate points is also removed. The primary content is then recorded without secondary content that originally comprised part of the original television content stream.
