Maidenhead, UK (September 7, 2007)–TSL is rolling out what the company describes as the world’s first 1080P compatible audio monitoring unit at the IBC show in Amsterdam. The AMU1-CHD Dolby is capable of de-embedding and decoding Dolby E bit streams from HD/SD video formats up to and including 1080P.
Developed in response to a request by a major European broadcaster, the AMU1-CHD Dolby features dual HD/SD auto sensing video inputs with reclocked, downconverted and composite video outputs for integration with third party systems. Input audio is selected from any of four de-embedded groups (a total of 16 channels) plus four AES and two stereo analog input channels. An auto sensing Dolby processor decodes Dolby D or E bitstreams from either AES or HD/SD inputs and a dual 26-segment bargraph plus full bandwidth internal loudspeakers allows the user to select and hear stereo or individual multichannel audio pairs. The LtRt mode activates a metadata determined stereo downmix mode essential for monitoring the final audio heard by the majority of consumers in the home.
Audio output connections include decoded multichannel variable analog signals, which can be used to drive a set of active 5.1 speakers in an environment such as an MCR or ingest room, where higher listening quality may be required. A fixed or variable AES version of the decoded multichannel outputs also enable the user to connect to external audio devices such as mixing consoles, processors or an audio vectorscope.
Housed in a 1RU chassis, the AMU1-CHD Dolby compliments TSL’s Cameo product range. A compensating video delay to adjust for the one-frame Dolby E decode cycle will be available from Q1, 2008.
