Phabrix adds Dolby E/ED2 decoding and metadata option for Qx and QxL Series
Phabrix has included a new Dolby E decoding and metadata analysis option in the latest release (V4.6) for its Qx and QxL Series rasterisers. The PHQXO-Dolby option allows users to decode a Dolby E or ED2 Dolby Atmos audio stream routinely used in live broadcast applications and obtain a clear view of Dolby E metadata.
The update heralds a host of additional benefits to customers working with Dolby E or ED2 audio streams. Chief among these is a Dolby E decoder and metadata analyser that allows users to check the correct timing of Dolby E packets in the audio signal of an SDI or ST2022-6 broadcast chain. Providing a clear and accessible view of Dolby E metadata, the option also makes it possible to monitor Dolby audio from any of the SDI/2022-6 embedded audio, 2110-30/-31 audio flows or AES inputs.
PHQXO-Dolby also enables metering and monitoring of the decoded audio, along with the ability to separately measure the loudness of a 5.1 or stereo 2.0 decoded program. A new ‘Dolby view mode’ is provided for the audio meter window which displays the eight channels of decoded Dolby E audio together with a configurable stereo 2.0 downmix, while the Dolby program metadata facilitates automatic identification and configuration of the meter channels. A status display of parameters presents Dolby E source, line positioning, dialogue level and downmix program source. Decoded audio may be routed to the AES outputs for external monitoring.
In addition, users can take advantage of built-in cyclic redundancy check error reporting, which affords a real-time check on the creation and transfer of the Dolby E stream through the broadcast network. Moreover, for SDI and 2022-6 interfaces, a live update of Dolby E line timing is provided. Colour-coding of the line number label indicates when the line number is within the ideal range (white), within the acceptable range (yellow) or outside the acceptable range (red).
Phillip Adams, CEO, Phabrix, commented: “The story of our Qx and QxL products is one characterised by refinements and additions, and that continues with this latest release geared towards broadcasters working with Dolby E or ED2 audio streams. With the V4.6 release they now have access to a host of decoding, metering and monitoring capabilities that will ensure their Dolby audio workflows can be managed and processed more easily and efficiently.”
