Sony has developed a system to record and play high resolution HDTV video to/from semiconductor memory with a small capacity such as "Memory Stick PRO."
Application of this technology would allow for the company's "Playstation Portable (PSP)" portable gaming device to view HDTV video.
Data compression technology called "MPEG-4 AVC" is being used. It compresses about twice as much when compared to "MPEG 2," which is currently used in TV broadcasts, DVD recorders, and so on.
HDTV video signals using MPEG-2 have a transmission speed of about 24 megabits per second. With MPEG-4 AVC, Sony compresses the same HDTV video signal down to 10 megabits per second, so that even on a device with a small data capacity, the high resolution of HDTV can be retained through their proprietary video processing technology.
One type of the company's semiconductor memory, "Memory Stick PRO," has a data write speed of at least 15 megabits per second, which would be plenty for recording and playing.
HDTV supporting TVs that allow details as fine as someone's hair are popular, but this announcement is a step towards the implementation of HDTV video on mobile devices.

Sounds like a fair bit of PR spin, basically just touting the benefits of the AVC/H.264 encoding in the 2.0 firmware. No actual Hi-Def resolutions can be displayed on the PSP obviously as the LCD just isn't physically capable of fitting even a 480p image onto it, much less 1080p.
