Of course it's possible. The decompressor handles that of course, just
like video codecs "generate" (ie. do nothing) inbetween frames for
low-framerate video played on a high-refresh device (ie. television or
monitor).
The point isn't how many pixels can be represented by bits, but by how
much state change information (ie. how many DIFFERENT pixels) can be
represented by bits. With a video bitrate of 1 bit per second, the
most that video could possibly be is the entire screen being 1 of two
colors (I chose white or black for ease, but they could be any two
colors), once per second.
