Hey there... I was just reading up on VCD and SVCD tonight (Video CD,
SuperVCD)
and wondering to myself, why does the Sony MD-Discam only fit 20 minutes of
A/V
onto a 650MB MD? Of course, I realized that the Discam is using much less
compression. But wouldn't it be cool to have an MD-based movie player that
played SVCD format? (MPEG2 video compression, up to 95 minutes on 650MB,
depending on audio quality...) The VCD web sites I visited talked about a
typical setup using 224kbps for audio and the remainder for video, but that
using 128kbps audio and leaving more bandwidth for video was a better idea.
Makes sense to me. By that logic, even better would be 105kbps ATRAC3
audio...
I think the next MD-Walkman needs to be an MPEG2 realtime Video recorder.
Just
as tape progressed from audio to video, it seems the next logical step for
MD.
The Discam was an interesting proof of concept but they really need to take
it
further now, and put an i.Link interface on it...
