sa:
Television or other broadcast. The heavy banding around 15.75 is a video crossover frequency. Most analog broadcast signals have cutoffs around 15k and digital around 16k, unless it's Dolby Digtial which cuts around 20k. The brittle distortion is probably analog broadcast compression which generally happens twice in the chain, once in post and once at the satellite feed uplink.

So yes, less than ideal, but technically lossless.
