Eyeheight’s new AD-2EM audio descriptor will be introduced at IBC 2012. It enables broadcasters of high-definition television programmes to monitor pre-encoded data containing audio and pan/fade information.
Designed for use in master control rooms and playout suites, the AD-2EM decodes audio description and control data from audio embedded in the HD-SDI transport stream. It generates an in-vision display of audio level, fade and pan information. A status bar shows audio description errors such as swapped or inverted data. This display can be hidden and locked for automatic on-air use by audio description decoders.
A mix of audio description and programme audio is provided on embedded group 1, channels 3 and 4, with correct pan and fade response. Raw programme audio is embedded on channels 3 and 4 in the absence of a valid audio descriptor control track. In-vision error reporting is also provided.
Up to six AD-2EM modules can be housed in an Eyeheight FB-9E one-rack-unit smart chassis with an integral web server for monitoring and control. An optional FP-9 front panel can be added to allow local control via illuminated self-legending pushbuttons. The FP-9 can be linked to the FB-9E chassis by up to 250 metres of standard Cat 5 cable.
