A:AnswerI can answer for the slingbox 500 and why I bought that particular unit. If you have cable you, Direct TV, Dish, or whatever you can broadcast it over the Internet an watch it through your smartphone, computer, or roque box. I believe you can also watch other types of streaming like Utube, Netflix, and Sling has its own stations to stream.
A:AnswerYou do need both the cable box and Sling box but you can only send the video to one other receive app / device at a time. It can pass through to the local tv also but if either the remote viewer or tv viewer changes channels both the tv and remote see the same content
A:AnswerSling has a monthly fee. Although this device has the sling app and you're able to use sling on it...This device isn't affiliated with sling. If you want more information on sling and their prices visit sling's website
A:AnswerThe device does not receive local channels, that said there are aps that can do that. CBS Access has the ability to broadcast local CBS channel in a number of markets that will play on the ROKU - IF you subscribe and pay the monthly fee and you live in an area that is supported by CBS Access.
A:AnswerSling Box does not get any channels. You need to feed the sling box an antenna feed or a feed from your cable box. You can then sling any channel that you feed to it. Locals or whatever.
A:AnswerIf you want to be able to watch different programs simultaneously on different TVs, the Slingbox 500 Is Not the solution you are looking for. The Slingbox 500 will only allow you to stream the TV signal to one other device (mobile, web browser, or PC). You are limited to watching the same channel that is being viewed from the cable box. You can change the channel but you will also change the channel for the cable box viewer.
A:AnswerNo What ever was to go out to the tv is the video stream that will be encoded and transmuted to the receiving app device. You would need to cable boxes to do what you want.
A:AnswerYes. If possible try using the free trial. It will show you all the channels in your area. Also, I recommend Playstation Vue. You can use Amazon Firestick or Roku (recommended). The best part is there are no contracts and you can cancel after one month.
