TV signals over LAN..

Archived from groups: alt.internet.wireless (More info?)

Hi all,

I was wondering if anyone out there know of a solution to send TV-signals
from a video, satellite receiver or DVD player over a wireless network.

WHat I was hoping of finding was some sort of adapter that would for
instance connect to my DVD in the living room, and send these signal via my
home network to my pc..
Is this possible?

Regards,
Tony

Now let's see..

DVD, so call it 600 x 500 resolution (close enough.) DVD is known for
the rich colour, so suppose 16 bits per compression (should probably
be 24 for this calculation.) That's 600,000 bytes of data to transfer per
frame, and it should go at 30 frames per second (if not higher.)
That makes 17 or so megabytes per second of data transfer, which is
within the limit of a -good- 802.11b system.

So perhaps not impossible (but I don't know anyone doing it.)

If you were going to do this, you'd probably want a device in the
middle that did something like JPEG2 compression/decompression
to reduce the data volume.

There again, the "normal" way of displaying TV signals on a PC is by using
some sort of WINTV card or PVR ... these usually have inputs for Composite
in and audio...

There are wireless links for TV and audio (Video Senders) which connect to
your VCR/ DVD via Composite or SCART, and deliver the signal over the
wireless to the sister unit which outputs the signal as Composite / SCART
.... I can see no reason why this should not be connected to your PC TV
input...

Not sure what the quality would be like mind ..

Interesting that the Video Sender is essentially an analogue device ....
maybe digital just cannot hack it when it comes to large bandwidth...
