The PlayStation 3 PlayTV software has been updated to v1.21 today. The biggest change in the 24MB patch is the ability to watch, pause and record high-definition TV, though it’s not clear which countries this feature applies to. Other features include multi-channel audio playback, improved remote play usability, better SD upscaling, and support for Sony’s Aino remote play.

The HD functionality will require a new tuner. Australia will be the first country to receive HD PlayTV when it launches later this month. The new PlayTV box will feature twin HD tuners and a EPG. The device will cost less than $200, according to SCE Australia chief Michael Ephraim.
