Our DSL is 1.5/734 and the 734 upstream bandwidth has given us a high quality feed. The Slingbox adjusts video quality based on available bandwidth. I'll report back here on how the dual feed test goes.
We performed this test earlier this week. As promised, here is my report:
In addition to the information about our configuration that I posted previously, I should mention that I did not make any attempt to allocate bandwidth between the two SlingBoxes through router configuration. I would have pursued this had the need manifested itself.
At the beginning of our test the person helping me at one of the two broadcast destinations was using a MacBook with the Mac version of the Sling player software. He kept having problems with the player dropping it's connection to the SlingBox. He speculated that the Mac version of the player application was probably buggy.
After switching over to a Windows PC and running the Windows player, he had no further connection problems. The player app at both broadcast destinations had default options set as follows:
Video - Buffer settings: automatic - Optimizations: Enable SlingStream optimizer and Enable fast start - Home Network Video Quality: Full Resolution
Encoding - Medium Action
I was worried that whichever SlingBox was connected to first would get and keep a bigger slice of the bandwidth. But as it turned out, within about 15 seconds of when the 2nd SlingBox was connected to, they evened out to where they both were using about the same.
The bottom line is that while there was some loss in video quality with 2 concurrent streams versus a single stream, the audio quality was fine. The video was definitly not broadcast quality but good enough for our purposes. The members who will be viewing these broadcasts are very grateful that we will be saving them from long drives to and from some of our stake meetings
