Imagine a digital picture frame that has enough pictures on it to last a lifetime without repeating. Assuming 60 seconds per slide, there are 36,816,444 minutes in 70 years. Cheap frames these days have 320 by 240 pixel resolution. JPEG 2000 does acceptable compression at 1 bpp (bits per pixel), or about 96% compression, yielding about 10000 bytes per image. All the pictures together will total 354 GB, which is possible using today's technology. Multiply by appropriate constants for higher resolution or more rapid frame rate.
The early adopter for this technology will probably be the same early adopter for any media technology, and fortunately there probably are 36 million pictures in that genre.
It will be a challenge to build a digital picture frame that will remain functional for decades.
