Mobile TV and Portable Video Convergence

If you recall my first post (just yesterday), I told you that this blog will cover both live mobile TV streaming services, and portable "TV-to-Go" services such as those available on Apple's video iPod and other devices. Business Week posted an article by Olga Kharif yesterday claiming that these two markets are bound to converge, with mobile TV broadcast services providing content not only to cellphones, but to portable video players such as the iPod as well. This makes a lot of sense, since these devices have larger screens than cellphones, making the mobile TV experience more enjoyable. In addition, it is much more convenient to get TV programs beamed directly to the device, rather than having to wait until you get back home, connect the device to a PC, and download the programs from there.

Note that viewing TV on mobile broadcast networks will not always be a real-time experience. Most of the T-DMB and S-DMB mobile phones in Korea, and the prototype DVB-H phones available in Europe, have built-in PVRs, which enable recording of live TV programs to the phone's memory. In addition, both the DVB-H and the MediaFlo standards include specifications for "filecasting", which is a method of broadcasting files to the mobile device in offline. These files can later be viewed at the user's convenience. So, instead of downloading yesterday's TV episode to your PC and then transferring it to your video iPod, you could have the show "beamed" to your device overnight, and enjoy it the next day.

I'm sharing the view of Mobile TV device convergence. I've been watching video clips on the PSP device and the picture is so nice. I think the size is perfect for a portable device.

And this would implicate, for a city such as Hong Kong, where lots of people (I mean, ppl over there are addicted to portable devices such as PSP) use PSP, would benefit from a seperate broadcast network such as DVB-H for watching mobile TV, since the receivers for technologies such as DVB-H is relatively cheap.
