Remote Viewing - slingbox pro, remote viewing


The Slingbox Pro does an excellent job of streaming video from multiple sources (Tivo's, cable boxes, or satellite tuners, for example) to any internet-connected computer, anywhere in the world. If you have access to a fast internet connection, you'll be amazed at the quality of the picture and the sound.



Two issues:



1) The primary, defining feature of the PRO verison of the Slingbox is its ability to "sling" high-definition video across the internet to your laptop. It's unfortunate that the folks at Sling Media:



- saw fit to design the box to use a proprietary cable instead of the industry-standard HDMI cable that all HD component owners know and use, and



- failed to include their proprietary cable in the box with the Pro. When I buy a product for its PRO features, I shouldn't have to go back out and scavenge for a rare, $50.00 cable in order to use those features. This was a terrible oversight.



2) Be aware that you will not be able to use the Slingbox unless you:



- can plug it directly into your home network router, or



- purchase a $50-$90 wireless Ethernet "bridge," or



- purchase Slingbox's bizarre and expensive hardware solution for connecting the Slingbox to your router over your electrical wiring.



A PRO-level, premium product should be able to see and use a wireless home network connection, right out of the box; a trip back to the store to buy more hardware shouldn't be necessary.



The core product is great, and works better than advertised ... but this PRO package lacks what any pro would expect to find in the box. Be aware that, in addition to the Slingbox Pro, you'll need to buy:



- a home network router (if you don't already have one),



- a wireless G network bridge or the Slingbox networking product (if you don't have your router near your television), and



- a proprietary video cable (if you want to "sling" HD programming). Sling Media Slingbox PRO (SB200-100)

So by now you probably know what this is: A thin ethernet client (read: single purpose computer) that takes video from your home devices and streams it so that you can watch it on a PC or other compatible device anywhere in the world with internet access. You get to control your home device through a virtual remote that sends IR signals through an IR "blaster" cable that connects to the Slingbox and shoots the IR signals to your home device just as if you were at home with a remote.



Looks good on paper. But does it work? Having a lot of experience with streaming video, I was very skeptical. In general, I've found that streaming video eminating from high bandwith commercial servers still results in videos that continually freeze as the buffer runs out. Just how could this Slingbox, which has to squeeze its broadcast signal through the intentionally crippled upload connection of a typical cable connection, possibly deliver the goods to the receiving device in a fashion that allows a good, non-stuttering, non-freezing picture? (In case you don't know, almost all home cable/DSL connections are limited by the providers to about 30kpbs upload speed; compare that to download speeds that range from 768kbps to 3mbps! This is done intentionally so that people don't use their PCs as web servers unless they pay much higher commercial rates).



Anyway, I installed the Slingbox (trivially easy if you have ever installed an A/V component before), installed the software on a PC (Windows 2000 or XP required, sorry you ME, 98 and NT laggards), and let the Slingbox installer do its thing. It asked me some simple questions and I was done.



Installation was quick and painless, but what about the real question: How's the streaming video quality? Well, on my home PC, which obviously has an advantage since it's on the same network as the Slingbox, I can get great streaming video. But that's no real challenge.



So I went over to a friend's house, where there's a kinda miserable DSL connection, installed the Slingbox player, and fired it up...And guess what? After about 30 seconds, where the slingbox player was adjusting the compression/resolution in order to provide stutter free playback, the picture was rock solid. Better than anything I've EVER experienced with video from any web server. And it stayed rock solid. W-O-W!



I'm sold. This product is for real. What a great product.



As for whether you need the Slingbox Pro, or the cheaper models. The pro adds capacity for multiple inputs, an integrated analogue video tuner (so you can watch EITHER cable or your attached DVR/VCR/DVD player/cable box/etc), and the abilty to stream the output of a HD (high definition) device. HOWEVER, be aware that to use the HD input to the Slingbox, you need a proprietary cable that is NOT included in the package (and which will set you back about $50). That kinda sucks, and I almost docked the unit one star for that bit of bait and switch (the box touts its high definition capabilities but doesn't really say that it will cost you $50 more to use them), but I'm so happy with the performance of the box in general that I'll let that slide... - Tv - Remote Viewing - Internet Tv - Slingbox Pro'
