Apologies if this is a stupid question, but when connecting AV equipment (BD players, receivers etc) to the internet to carry out updates, is there any risk of picking up harmful material in the same way that PCs can become infected with viruses? Would it be possible for someone to write some sort of program that could 'trick' the player into thinking it was a useful update and subsequently cause it to malfunction? Is it only a matter of time before we see Norton, McAffee etc selling virus protection for AV equipment?!
My guess would be Sony have built in some sort of certificate (or similar) system to ensure the player knows it's talking to a Sony update site to guarantee that any updates come from Sony themselves (or whichever manufacturer is involved) rather than an unsavoury source. Of course no system is 100%, but this is would be one of the most secure systems and is the means by which virtually all internet security is carried out e.g. online banking and shopping etc.
So in theory someone could break this security, but given the knowledge required and complexity of doing it, and the lack of incentive for doing so (i.e. you're not going to make any money out of hacking into someone's Blu-Ray player), I would say this is fairly unlikely.
