Hitachi TVs to identify themselves online

If you've ever used an internet-connected TV set to watch pay-per-view programming, you'll know that they ask for an authentication password every time, which can be a mild irritant. If only they could act like computers and remember what they've been granted access to or not - something Hitachi Japan appears to have solved.

A one-off authentication should allow software embedded in the sets to remember what they're approved to connect to in much the same way a cookie functions on a PC, albeit with greater security.

Hitachi hopes the PKI method will become standard for delivering online programming without a set-top box, something its participation in the Japanese acTVila VOD service makes very likely indeed.
