hi everybody
I've been thinking about a way to improve the way files are carried for exchange and playback.
Talking about encoding and playback software. eg video2nbtv
at first instance the sampling frequencies used are quite inflexible I think, for most 32line 400hz line 12 and half frames per sec. using sampling freq below 22khz for B/W low quality videos are ok. even 4-8 kHz room for video is enough to watch intelligible forms and movements.
second there's a waste of space on left channel for only baseband mono audio.then I started testing some files that might content Stereo Sound on left channel and or More than one video, audio channels using AM Qam modulation inside a WAV file.
