RE: Maximum USB

["Amar Nagi" <groups@xxxxxxx>]

I have just thought of a potenial solution

I have a av hub with remote control (about 30quid)
I have a tv card which was 15pounds.

I could control the signal i want to monitor by remotly controlling
the av hub via infrared. 

All i would need are some budget cameras (b/w) and software that is it
i think

anyone see a problem with this ? what software could i use

      First public version will be a small client
with a mediaplayer frame inside and a listbox with all the available source
at the encoder.
      You will be able to remotely select one of
(let's say) 4 USB connected webcams.
      The list will be loaded at startup with all
the available source (can be audio, video or AV).
      In this moment I have 3 USB webcams (with
mic included) and the AV receiver output connected to a Pinnacle Lynx USB
AV cable (again with his own mic).
       
      In that way, I can use the system not only
for surveillance purpose, but even to remotely select one of the home
entertainment system AV sources (vcr, sat, TV, DVD) using Infrared Remote
Manager.
      Even when I am abroad, I can see my
favourite radio/tv program using Windows Media streaming.
       
      Sounds interesting for you?

      Hi, 
           
      
           
      I make some tests. Theoretical limit is 5m
per segment for  a maximum of 5 segments. 
           
      Practically, using STP cable I get reliable
connection even at 10m. It is possible to get even more. 
           
      You can use the 8 wire like that: 
           
      - 4 for the standard usb pins 
           
      - 2 for power supply GND 
           
      - 2 for  +5V for the powered hub. 
           
      Take care that it is possible not to be able
to use 2 webcams on the same USB hub. Usually, one cam request aprox. 75%
of the bandwidth. 
           
      
           
      
           
      BR, 
           
      Dan 
           
      
           
      P.S. This is what I use in this moment. 
           
      I will post in a couple of days, on my site
(http://www.geocities.com/tdanro)
a small application to select one of the AV source connected to a Windows
Media Encoder remotely, when not home. 
           
      Is very usefull for surveillance purpose.
