again, I will repeat that I was describing current/prior use of HTML on
television devices; notwithstanding that fact, there is a desire to
progress these devices to a state where they can accommodate most common
web content; at the same time, there are some performance issues related to
current hardware which was how this subject arose; namely, that a solution
which relied upon or required block decryption in JS may be problematic; it
has been pointed out that exposing a block decryption API at the JS level
does not imply that the decryption algorithm must be JS, so this may turn
out to be a non-issue; i also pointed out (which Mark has further
elaborated) that the primary issue is going to be about whether decrypted
frames will be exposed at the JS layer, which is unrelated to performance
considerations;
