Made an experiment:
1. connected SONY camera's composite out to computer audio line-in
2. recorded incoming audio/video signal as sound using SoundForge program (stereo recording - one recorded audio (can clearly hear it), the other channel is video (hear as noise)); saved as WAV file
3. copied WAV file onto MP4 player
4. used composite audio/video cable (came with SONY camera), connected it to stereo audio output of MP4 player - connected it to TV
Results:
- heard audio signal (nothing special)
- picture on TV was just some noise (experiment failed)
-------
What went wrong here? How come picture didn't show?
How can it be made work?
---------------------------
Idea for this interesting little experiment came to me when I thought about if it is possible to make a program for Pocket PCs (Smartphone) which don't have TV out to emulate audio/video signal using Pocket PCs earphone terminal.
Can such program be made?
