RTP Madeira adopts new digital audio monitoring

Following the use of Bel Digital Audio’s BM-A2-E8SHD+ 3G, HD and SD multichannel Dolby E audio confidence monitor and de-embedder in its Lisbon facilities, Portugal’s state broadcaster RTP has installed several units on the island dependency of Madeira. Both installations are part of the move to HD throughout RTP’s facilities.

The units were supplied via the Bel distributor for Portugal, Auvid Cientifico.

BM-A2-E8SHDSimplicity of operation was key to RTP’s choice of these devices over the alternatives for monitoring their broadcast feeds. According to Auvid Cientifico Sales Manager, Antonio Vieira: ‘The units’ flexibility and the ease with which you can switch from monitoring one stream to another across all the available channels was quite obvious once we had demonstrated the Bel monitors to RTP. This was a key factor in their decision along with their full 3G HD compatibility and the units’ ability to decode Dolby E or Dolby Digital signals.’

The BM-A2-E8SHD+ accepts two SDI and two AES sources and automatically identifies between 3G, HD or SD video. Video format is then provided on the LCD. Up to eight de-embedded audio channels can be selected directly from its front panel rotary controls and visually displayed on eight individual LED bar graphs. Each channel can then be routed to either, or both, left and right speakers. Dolby E bitstreams can be decoded (with metatdata) for monitoring purposes, while all eight decoded channels are available on the rear panel for connection to external speakers. A very intuitive user interface removes any requirement for menus.

In addition to relaying feeds from RTP1 and associated channels, RTP Madeira has its own production facilities and generates programming and news for cable distribution to the Madeira Islands and via satellite for the Azores Islands.

RTP on the mainland broadcasts one main terrestrial TV channel within Portugal, while also broadcasting several other channels via satellite or cable TV service providers. These include a sports channel and an international Portuguese language channel intended for former protectorates such as Angola, Mozambique, Cape Verde, Macau and East Timor. The Bel monitors are directly employed in the transmission stream for confidence monitoring in relation to all output.

The Bel 3G HD range has also recently been used to good effect in all the technical operations centres at the World Cup in South Africa, along with several of the trucks used at the event.
