Hunt for the Tomb of the Cybermen As soon as the decision was taken, the problem of satisfying demand surfaced: It should also be remembered that the first domestic video recorders would not appear until the late 1970s, and there was no market for home video for close to the first two decades of the show's history.
Welcome Your IET account. Many of the recovered film reels have been found in the archives of overseas stations or found their way into the possession of TV staff who kept them when the broadcasters asked for them to be discarded.
Huawei threat, tech's Wild West, education apps and more: When it came to preparing a VHS release of 'The Daemons' 1971 in the early 1990s, the only broadcast-quality source available for all but one of the episodes was a set of monochrome 16mm film negatives. Without filtering, film captures both signals.
The film used was typically very slow, providing it with a very fine grain able to capture minute details. These days, both fields are created from motion estimated frames at 1.
In 1991 telerecordings of all 'Tomb of the Cybermen' episodes were finally recovered from the Rediffusion Television in Hong Kong. Doctor Who set to land in VR headsets.
With the release of episodes in the past few years that employ these recolouring techniques, the Doctor Who Restoration Team has more or less completed the task of bringing the colour Doctor Who serials back to a state very close to the original viewing experience; there may even be opportunities to improve on the original remasters.
Despite being recorded on monochrome media the colour information had not been stripped out. Foldable screens and 5G compatibility steal the show at MWC.
The VidFire system has also been used in the restoration of archive programmes other than Doctor Who. Although BBC television managed to keep an untransmitted version of the first episode of Doctor Who recorded 50 years ago, the organisation wiped more than a hundred others made up to the mid-1970s.
A bit of technical knowhow Only one serial was preserved in the form of colour film — the consequences of a studio-based strike during production. No other TV series has been able to call upon a restoration effort in the way that Doctor Who has. Former BBC engineer Richard Russell developed software that could filter the colour information and correct distortions.

Black-and-white film captures colour information from a video signal because of the way that the colour signal is mixed into the video fields. The result is generally flashes of spurious colour.
