JapanChronicles.com has the scoop on Sony's Portable TV service (P-TV), which is currently available to PSP users
in Japan. Despite offering valuable content (downloadable PSP-formatted videos), the P-TV service is flawed. All of the
videos are DRM-protected and only accessible for a limited amount of time (ranging from 5–30 days) — each
video must be bought separately (some videos are free).
If Sony wants to stay competitive with services like iTunes, the company will have to give downloaders full ownership of downloaded video or move to a fixed low-cost subscription fee. That is, either sell users videos to download and keep, or charge them a monthly fee that will grant access to all (or part) of the video library, giving users a limited time to watch a downloaded video, but also permitting them unlimited monthly downloads. Given the Memory Sticks' limited storage capacity, users should also be given the opportunity to archive content on a PC.
