I think JPEG 2000 is simply the chosen format for distribution of the video, not for security.

JPEG 2000 has some interesting properties for very high quality video storage and transport where bandwidth is not a concern. The traditional encoded video formats we know are less preferred at this scale.

JPEG 2000 is resource intensive, though. The decoding hardware is probably either GPU based or using an FPGA implantation from one of the providers who makes hardware for this.

It's definitely dedicated hardware JPEG2000 decoding.
