The radio spectrum is licensed or controlled by the FCC. The 2.4 GHz frequencies available to RC control are defined to have a very limited bandwidth, and thus would not support the wide bandwidth that video requires. The 5.8GHz frequencies are allowed to use a wider bandwidth.
Note that at higher frequencies, a fixed bandwidth chews up a smaller percentage of the frequency spectrum around those frequencies. So essentially, there is more room available.
