The Dolby support on the PHABRIX Rx range is extensive. The Rx Dolby bitstream analyzer option adds significant Dolby E, Dolby Digital and Dolby Digital Plus audio analysis features to the Rx range. This is available on the Rx2000, Rx1000 and Rx500 rack mount instruments. The option allows the display of Dolby E, Dolby Digital and Dolby Digital Plus metadata present in a selected audio stream and determines whether the Dolby-E packet is timed correctly on the SDI video stream. The Dolby metadata may be monitored from any of the SDI input embedded audio channel pairs or the AES input.
