Sonifex Show Dolby E Encoder & Decoder Redboxes At NAB 2012
11th April 2012
Sonifex are showing on booth C2739 at NAB 2012 the Redbox range of video embedders and
de-embedders which include Dolby E decode and encode processing.
Still in the familiar Redbox chassis and offering rackmounting as standard with a universal AC power supply, these new video Redboxes use latest technology components to offer embedding and de-embedding for analogue and digital audio signals into and out of all 3G, HD and SD-SDI video signals, respectively.
The Redbox RB-VHDDD8 is an SDI audio de-embedder and re-embedder with Dolby E & Dolby Digital decoding capabilities. It de-embeds 16 channels of audio within any audio group of an SDI video signal and a further 2 which are sent to the Dolby® Decoder. Up to 10 channels from the decoder or any of the 16 channels from the de-embedder can then be re-embedded onto either of the two SDI outputs and also transmitted on a BNC or D-type situated on the rear panel.
The new Redbox RB-VHEDD8, which is an SDI audio de-embedder and re-embedder with Dolby® E encoding capabilities, encodes 8 channels of audio into two channels of an AES/EBU digital audio stream which is then embedded onto any of the available groups within each of the two video output paths. The encoded Dolby E bitstream is also available via a dedicated output on the rear panel. The audio inputs to the Encoder can be selected to come from the external digital audio inputs or from embedded audio contained in the incoming SDI input. The outputs from the de-embedder can also be re-embedded into the video outputs, along with the encoded inputs.
The audio inputs to the encoder can be selected to either come from the external audio inputs via the BNC or D-type connections on the rear panel or from the audio in the incoming SDI input. Similarly, the metadata input for the encoder can be selected to either come via the external 9-pin D-type on the rear panel or from metadata embedded into the vertical blanking area of the video input.
Both units are controlled locally through the front panel display but can be remote controlled via an ethernet connection using the Sonifex SCi software, through which metadata can also be viewed.
