Streaming server/client software needed for main office to branches multimedia stream

[vlata]

Hi everyone,

This is my firs post. I will start right with the problem: I need multimedia solution for my company. We have several branches all over the country, each branch have 4-6 LCD displays on which we play commercials, daly promotions and music. The signal comes a from local PC with TV out. What I need is to centralize all that stuff. What I mean is, I have to implement a multimedia streaming server in the main office, and a audio/video client in each branch. There are many streaming servers out there but it's hard, because I need:

- Every branch have different daily promotions and commercials, so I'll have to create separate accounts and programs.
- Sometimes the connection drops, so the player should have a huge buffer (about 30 min.)
- The audio/video stream should be programable (e.g. play commercial_1.avi every round hour, play promotion_5.avi every 45-th minute of the hour, play Rock Music folder 30 min., then Pop Music folder for 10 min., and so on...)
- The streams have to be locked to a specific IP address, so that n.o. else is able to connect to the server.
- During the music playback, a video with the company logo should appear on the screens (so the server should support different audio and video sources)

All that sounds pretty much like satellite radio, but we can't use satellite radio in our region. Can someone help me find the right software for the task. The platform should be Windows or Linux (no Macs). It doesn't matter if the software is freeware or paid. Thanks to all willing to help

P.S. Sorry for my English
