Normally, when seeking to put into effect some protocol, you might be constrained through your {hardware} and time. However for any person like [EMMIR], that’s no longer sufficient. For instance, NTSC-CRT is a video sign encoding/interpreting simulator with out a {hardware} acceleration, floating level math, or third-party libraries. Simply elementary C.
Whilst NTSC has formally long gone darkish in The usa, other people nonetheless make their very own ATTiny-powered transmitters. NTSC is a little of a abnormal usual and is on occasion known as never-twice-the-same colour, but it surely does produce a definite glance.
That glance is what [EMMIR] was once going for. It encodes a message in a ppm structure into NTSC after which again in ppm with some configurable noise. It could possibly do that in real-time as an impact in [EMMIR’s] engine or on a rendered symbol by the use of a CLI. It seems to be improbable, and there’s one thing very gratifying. Since there it doesn’t come with floating level, fastened level with a (20/12 or 21/11 ratio of integer to a fragment). There’s a video after the wreck appearing off the impact. The code is lovely brief and simple to learn.
