    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.

    摘要: A closed caption detection system includes a video line selector that outputs a selected line of a video signal, a luminance detector that outputs a luminance level of the selected line, and an alarm that compares the luminance level with a threshold level and provides an alarm based on the result. A method of detecting closed captioning data includes selecting a television channel, decoding closed captioning in the channel, detecting a luminance level of a closed captioning line of the television signal, comparing the luminance level with a threshold level, waiting for a time if luminance level of the selected line is less than the threshold luminance level, and then re-detecting luminance level and re-comparing the luminance levels, then, if the luminance level is less than the threshold level, indicating the absence of closed captioning data.
