Abstract
Abstract A television transmitter for transmitting a television signal representing a series of scenes, the series of scenes having a non-program-content characteristic. The transmitter includes a processor for processing the series of scenes so as to retain a non-program-content characteristic of the series of scenes, means for inserting identification information into the television signal, the identification information being indicative of the non-program-content characteristic retained in the processed series of scenes, and a signal transmitter for broadcasting the television signal. Also disclosed is an advanced video system for receiving, processing and displaying received source material having non-program-content characteristics. The system includes a classifier unit for identifying different classes of received source material based upon the non-program-content characteristics of the received source material, and an adaptive processor unit for treating each class of received source material according to its non-program content characteristics.
