    well, I would certainly not post links to the multifeeds, thus encouraging their use, for the time being.  But the multifeed sites are apparently breaking things for the single feed users as well.

    CNN is no substitute for me because I was recording the video.
    Although I would not be surprised if CNN was also using Akamai to stream the actual video; many of the big players do.

    •  CNN has there own camera aimed at a monitor. (6+ / 0-)

      They had multiscreen on the monitor Congressman Markey was given and they pointed a camera at it and moved it occasional.

      I saw them do it.

        I thought they had multiple monitors but pointing at one monitor is also consistent; I didn't look too close.  I could tell they were using a camera rather than doing it digitally.

        Key thing is they were only sending one stream of relatively low resolution and hence low bandwidth.   Downside was you only got a postage stamp of each feed.

        These new multifeeds are just web pages which embed one of each video stream.   Looked like some even scaled it down so you were using the bandwidth for a quarter SD resolution image but only seeing some of the pixels you "paid" for.

        Now imagine one SD stream.    Top half divided into two pieces (left and right) displaying the two most interesting cameras at the moment.   Then the bottom half can be divided into 8 pieces to show the others.    If you have less than 10 cameras, you can use some of the other space for other information.   Digitally composited.  This would give you about the same resolution you are getting now and let you see all the cams with one feed.   Probably use about 4 times as much bandwidth since it has 4 times the total resolution.   Except that most of the ROVs don't have much to show so you don't have to send much for them and you are basically divvying up the bandwidth for the cameras that need it.   This is the junior version of the HD version which needs more bandwidth.   Broadcast it on some of the throwaway extra ATSC digital TV channels (how many 24 hour weather channels do you need?), cable, and satellite as well as internet.
