Justin Mitchell, a principal engineer at BBC R&D, shared the details about a recent NICAM Codec replacement project at BBC Radio, in which the old and failing equipment (installed in 1983) was replaced with new devices centered around the Zedboard with the Xilinx Zynq FPGA chip.
The new equipment replaces the three data combiners, the 6-channel audio coder & decoder, the CRC inserter, the CRC checker, three data splitters, as well as the NICAM test waveform generator. It was a big job for an overnight installation considering the number of listeners BBC Radio services.
So, when millions of people woke up the morning of November 20, 2015, and tuned into the BBC national radio services, they were blissfully unaware any changes had occurred. For such a massive technology change project, “this is an excellent result!” We can’t help but agree with Mr. Mitchell.
