I will be using the hava to remotely connect 100% of the time. The hava and tuner would be set up in a datacenter with dedicated upload bandwidth of no less than 5Mb... ever. So my question is will the hava use all of this bandwidth for a 720p HD stream? I have seen Sling Pro-HD's streaming around 2000Kbps and while it's OK, I would really like better HD quality. I seem to remember reading somewhere that the Hava's WAN viewing was capped? Is this true?
Thanks, -J

Another quick question... if I input a 720p stream via the component inputs, what resolution does the hava downconvert to. Or maybe a better question is, what resolution stream do I receive on my Windows Media Center PC 1500 miles away?
I am trying to figure out whether to buy the Hava or the Sling Pro-HD. Most people who view remotely don't have nearly the dedicated upload bandwidth I have, so I am having a hard time finding out which I should get.
Thanks, -J

Sounds like the Pro hd is the best for you today. The hava will take your 720p in downscale it to 480i then stream it remotely at 320x240. It's still a good quality stream if you ask me. With the pro you can get the same 720p

The problem with slingboxes is that they use TCP packets and if you have latency over 200ms then the slings remote speeds are dramatically reduced. You can have a 5mb upload and only get 1mb on a sling if over 500ms latency or 2mb on 250ms latency. HAVA uses UDP and is not affected like this. I am streaming from the UK to Taiwan on 5mb uploads and get 3.5mb - 4mb on remote streams. Thats means I can stream the SKY UK HD. Cannot get more than 900k on a sling HD PRO due to latency. Even at 2mb on remote the SKY UK package is still crystal clear even if on SDTV and not HDTV.

you keep saying this but I don't think you're correct. Every sling I have seen forwards udp. It doesn't make sense to use a connection oriented protocol for video. It would have to pause the stream everytime a packet was lost(to wait for retransmit) or Showed up out of order. I wouldn't bet my life on it or anything but I'm not sure what you're saying is accurate

SHow me anywhere in the sling setup for remote viewing that is not port forwarded to anything other than TCP packets. Slings use TCP on remote streams.

you have to forward both tcp and udp packets
use a sniffer like wireshark to look at the actual packets

ok yes I have done that a long time ago. Never mind. I am talking from experience from hosting many different types of streaming devices.

And I work at an ISP that streams tv over dsl, doing network support on that architecture. Sure we only have a couple hundred thousand end devices. I'm sure you have many more.

All slingboxes are they?

I know, I feel horrible about it.  seriously tho, most of is prefer the hava to the sling, but there's no need to spread inaccurate information

I recommeded the sling pro over the hava for this original poster because 720p was most important. HH is correct about the tcp and latency issues with the sling however he said he was using a datacenter for the sling location.
"So my question is will the hava use all of this bandwidth for a 720p HD stream?" -OP
No it can't. It streams remotely in a mpeg 4 format only. Even if you got 10mb remotely its mp4 and 320x240 where the sling pro HD can send .264x format and at 1280x720.
As far as the udp vs tcp aspect both hava and sling use udp and tcp. The sling streams TCP over the internet and udp to the local network. I think if the sling sends any udp streams over the internet they are called snatt. Snatt uses a tcp tunnel to send udp streams when it proxys but still bound by tcp rules. Hava uses udp streams and more than 1. It requires a tcp connection to the hava servers not between your hava and client.
The slings tcp stream allows it to easily route the streams to any port. The hava udp stream is limited on purpose because its often blocked by isp's. The hava is blocked by most corporate firewalls and can't be configured to use specfic ports

The facts there say udp-based streaming. Is that not udp? Self-triggering multi-layer connectivity algorithms to eliminate the complexity of home and external networks for 100% reliable and automatic connection, with three methods of connection: TCP, UDP, TCP via web proxy kinda misleading. But try this if the sling is on port5001 forward only udp to it. Then try only tcp and forward udp on 5001 somewhere else
