You haven’t actually explained why you claim I am wrong. You’re actually in agreeance with what I’ve said. The Sigma chip doesn’t run on it’s own you know…it runs in concert with the firmware loaded to the media box. A box with hardware only DRM means it can never, ever get additional features or updates. Firmware can never add additional DRM based services. So, for example - a roku box could never receive additional channels which require DRM, the way it picked up Amazon and MLB and all those additional channels later on.
And again, while game consoles may contain independent cpu/gpu processors, the majority of other devices do not but are able to gain functionality, so this bears 0 relevance to the matter at hand. Gaming consoles also do indeed TPMs to ensure that people aren’t easily able to run bootleg games and such. The PS3s TPM is even able to detect some pirated digital video files.
Also take into account devices like the Sony media player, Seagate, Roku as mentioned and even the WD NA unit which have all gained additional functionality from Netflix, Hulu, Pandora, etc. after release through firmware - this was attained with a simple software tweak to the TPM.
So I maintain that DRM is mostly software based, with hardware necessary on some accounts…I am not actually going against what you’re saying, I’m just making it clear. Decryption and decoding may be processed by the hardware (be it a secure processor, tpm, cpu or gpu) but the actual flags (meaning, checks and balances…actual ‘yes and no’ operations) are cued/controlled/initiated by software.
The source is here. The user got an error during play, but I suspect this is simply due to software flags not being flipped. For that same reason (completely software based), Netflix doesn’t work on some Honeycomb tablet while it works on others and also why a simple software upgrade allowed hundreds of Android 2.2 and 2.3 phones to now run Netflix.
Finally, I’m not opposed to the possibility of being wrong, I really am not. I’m clearly admitting that I very well could be. This is all speculation, after all. But so far it’s just not looking good. There are no scenarios in which it has ever been necessary to change hardware in order to deal with ‘different’ DRM in terms of any media device which supports it in the first place. So, that good ole’ Roku is going to pretty much run any DRM it needs to until it runs out of physical memory and likewise, so should the WD box.
In essence all I think WD would need to do is write some conversion firmware which sacrifices so and so US only apps and flips the switch to allow Netflix to work in said LatAM boxes. Alas, it won’t happen because that won’t make them any money.
