A signature is extracted from the audio of a program received by a tunable receiver such that the signature characterizes the program. In order to extract the signature, blocks of the audio are converted to corresponding spectral moments. At least one of the spectral moments is then converted to the signature. Also, a test audio signal from a receiver is correlated to a reference audio signal by converting the test audio signal and the reference audio signal to corresponding test and reference spectra, determining test slopes corresponding to coefficients of the test spectrum and reference slopes corresponding to coefficients of the reference spectrum, and comparing the test slopes to the reference slopes in order to determine a match between the test audio signal and the reference audio signal.

Interactive content preservation and customization technology is placed at the broadcast facility to ensure reliable transmission of the interactive content to a local subsystem. An interactive content code detector detects interactive content codes in the video stream at the broadcast facility. The interactive content code detector is placed in the transmission path before the video stream is transmitted to broadcast facility hardware that may strip out, destroy, corrupt or otherwise modify the interactive content and interactive content codes. Once an interactive content code detector detects a code, an interactive broadcast server determines what action to take, and instructs an data insertion unit accordingly. The interactive content codes or interactive content may be placed in a portion of the video that is guaranteed by the broadcast facility to be transmitted, for example, the closed caption region of the vertical blanking interval.

A DTV signal includes frames, and the frames include data segments. Data segments are replaced by codewords which represent digital data. The DTV signals are broadcast and received by receivers. The receivers recover the digital data from the codewords in the DTV signals, for example by using matched filtering. By using long codewords, the digital data can be broadcast over a longer range and recovered by simpler circuitry in comparison to the television programming contained in the DTV signal. In one implementation, the DTV signal is an American Television Standards Committee (ATSC) DTV signal.
