Re: Optimum App for Laptop: Bit-Rates?

I believe I found the ABR manifest XML file that is sent from the network to the ABR client in the capture. The manifest indicates there are four ABR streams made available for laptop streaming. I have listed these below (these are the MP4 video streams, audio is a 96 kbps stream that would added to the numbers below)

There may be a different set of streams for the iPhone/iPads, as these applications are not MS Smooth Streaming (Silverlight) based but rather Apple HLS.
