The group will sit down with BBC HD controller Danielle Nagler and BBC principal technologist Andy Quested at Television Centre in West London to discuss the "current poor picture quality level of the corporation's flagship high definition television service".
They will argue that BBC HD is failing in its obligation to "deliver a very high quality technical service to viewers, by adhering to, or seeking to exceed, industry standards for picture resolution".
After the BBC introduced new encoders on August 5, the bitrate on BBC HD dropped from 16Mbs to 9.7Mbs, a reduction of nearly 40%. Satellite viewers subsequently reported various problems with picture quality and sound on the channel, with some accusing the BBC of failing to deliver a truly HD service.
Paul Eaton, who has also appealed to the BBC Trust about the channel's technical quality, said: "The BBC should increase the bit-rate for its HD channel on satellite to 14-16Mbps, and increase picture resolution from 1440x1080 to 1920x1080 to be in-line with the majority of other HD broadcasters."
Last December, a petition was lodged on the official Number 10 website calling on the government to bring the BBC in-line with current European Broadcasting Union (EBU) standards by restoring the previous transmission bandwidth on BBC HD. It has now attracted over 2,300 signatures.
However, Quested recently discussed EBU recommendations in relation to BBC HD as part of his technical briefing series in response to the picture quality controversy.
Consumer publication Which? also ran independent tests of BBC HD material last year from the new and old encoder, but found that the difference in picture quality was "insignificant".
