Following on for my request for info on ISDN
digital telecomms components, on a related theme I am interested to know
what is available in digital cameras and for video compression.
Is it possible to buy such a thing as an "ISDN video
camera" - ie. a camera that can plug into an ISDN line? This
would need to compress the video data to 64 kb/s (or 128 kb/s if both of the
B-channels of a basic rate ISDN service are used).
Which chip sets are available to compress/
decompress video? Moving pictures are involved but low frame rates
would be acceptable.
I am thinking in terms of a project which
would transmit security camera pictures over a single 64kb/s B
channel. Ideally, I should also like this same channel to be used to
transmit digitised sound and route control data. This would enable
visual and audio monitoring of a remote site with the possibility of
controlling the camera pan and tilt motions.
Any ideas?!
I have heard of a protocol called X75 that may be
relevant. Any pointers to this?
Thanks and Regards,
Doug
