发明名称 METHOD AND SYSTEM OF MARKING AND RECORDING CONTENT OF INTEREST IN A BROADCAST STREAM
摘要 A system and method for marking and recording content includes a network operation center receiving an incoming programming stream, monitoring the incoming programming stream, generating descriptive data corresponding to the programming stream, combining the descriptive data with the programming stream to form a composite signal and broadcasting the composite signal to a receiving unit. The system may also include a receiving unit having a monitoring term stored therein. The receiving unit monitors the composite signal for the monitoring term within the descriptive data and storing content or sub-content in a memory of the receiving unit when a monitoring term corresponds to the descriptive data.
