Image+Audio
Posted on May 24, 2006
Hmm, wouldn’t it be nice if it was possible to view slides synchronised with audio recordings from past conferences on music/video players? Technology is there — MPEG-4 is supported by IPOD and 3G cell phones and they have enough disk space and CPU power. MPEG-4 can be used not only for typical video/audio combination, but for still images + audio. All we have to-do is scrape screens-shots from presenter’s screen and synchronise them with audio recording of the presentation. It would also be possible to insert an occasional video recording of a presentation between the slides.
File size would be really small, after all it’s just an audio stream, bunch of 320×240 images and some timing data. Typical player would be able to buffer ~5 minutes of the presentation, so it won’t kill the battery like music videos do. And because it is possible to protect the content with DRM like FairPlay, conference organisers and organizations like e-Concordia can give it only to the targeted audience.
Sometime it’s impossibe to visit a conference, so i think a lot of people would actually buy such conference recordings. For example would you consider to buy “Creating Passionate Users” by Kathy Sierra? What about a cdrom with every CUSEC presenatation in the format I described?
