Those were normally removed by the overscan of old TV sets. 
So my first suggestion would be: Crop
You also could also blur them away, by for example use KNLMeansCL with distance 0 and strength 20 together with an inverted rectangle mask, so that only the edges get filtered/blurred. (other denoisers should work too if set to high enough values)
