Program content is received at a headend of a broadband communication system, along with data concerning scheduled start and end times of the program derived from electronic program guide (EPG) data. After the program is broadcast, the actual broadcast start and end times of the program are compared with the corresponding scheduled times to determine whether there is any start and/or end time variance. If a time variance is determined, the content of the program is redefined to include only its supposed content. The redefined content is then made part of an asset for later retrieval and distribution.
