摘要： A method and system for diagnosing synchronization offsets in IPTV program signals includes generating audio counter values for audio packets and video counter values for video packets, such that synchronized audio packets and video packets have corresponding counter values. The correspondence may be fixed or may be a variable relationship during the IPTV program duration. The difference in arrival times of the audio and video packets may be measured at various IPTV network nodes, and compared to the IPTV program clock. Aberrant values for arrival times may result in a network synchronization alarm at an identified IPTV network node.

摘要： A method includes receiving digital audio data at an audio adjustment system. The method includes converting a portion of the digital audio data to an analog audio signal with a digital-to-analog converter of the audio adjustment system to form a sample analog audio signal. The method includes determining a dynamic range of the sample analog audio signal with the audio adjustment system. The method also includes modifying a metadata parameter of the digital audio data with the audio adjustment system when the dynamic range of the sample analog audio signal is below a threshold. The metadata parameter is a dialog normalization parameter.

摘要： A system that incorporates teachings of the present disclosure may include, for example, a server having a controller to monitor spectral characteristics of a target channel, a first channel and a second channel, where the target channel is of a digital terrestrial television system, where the first channel is an upper adjacent channel to the target channel, and where the second channel is a lower adjacent channel to the target channel. The controller is adapted to generate an emission mask based on the monitored spectral characteristics and detect interference between the target channel and at least one of the first and second channels based at least in part on the emission mask. Other embodiments are disclosed.
