Video Booth for Mobile Phones

Saw this post on . QR Code again !!! The concept is real simple. You go into this booth, record a short video and then download the video on your phone by scanning the QR Code that appears after the recording. QR code like other 2D barcodes can contain binary data and I assume the recorded video is converted to cell phone compatible video format and then dumped into a QR code. Once you scan the barcode the application recognizes that the data is binary data and after probing the mime type of the file launches the approriate player to display the video.

Download video on your phone without Bluetooth, Infrared or data service ???? amazing aint it... Now it seems easy with using a 2 dimensional barcode that can encode images and even video into a static image but I assume there is a very small limit to the size of the video that can be encoded. A 2 dimensional barcode does have its limitations on the size of data encoded and if you make the barcode big enough you can run the risk of having the barcode tooo big to scan.

Most Japanese phones out there are excellent pieces of hardware with a cool cool camera but lets think global here. Would such an app be popular in US or Europe or any other part of Asia ??? could be ... there are plenty of malls all around the place.

Whats gets me really interested in this though is the fact that I download a Video clip using my camera. Cannot stress this fact enough. No cables, No Wireless service .. No Bluetooth ..... aint this great.
Offcourse there is a limit to the amount of data that you can download and the speed of download when u are using the camera.... In the above case they were using just one 2d barcode to get the video clip but since the barcode is displayed on a LCD screen ... It could easily have been 3 or 4 barcode frames. Since the average time to decode a barcode is 200 ms , you could have the user point the camera to the screeen for 1 second and capture 5 different barcodes.. These inturn would then be appended together to create one huge clip .....

I am sure there might be people reseaching this area and the way I see it there are quite a few questions that need to be answered before actually coming up with a working scheme. But its worth a try ...
