Abstract
Methods and Apparatuses for content protection of broadcast flagged programs for digital television devices that use CableCARDs. In one embodiment, a filter is used to prevent program content in a clear format from being exposed on the CableCARD connector. In one embodiment, broadcast flagged programs in a clear format are filtered for a CableCARD so that no high definition version of the broadcast flagged programs can be easily recorded via the circuitry of the CableCARD. The filter may degrade the broadcast flagged programs, or zero the broadcast flagged programs, or delete the broadcast flagged programs from the transport stream.
