Re: Is there a delay on live tv on sky stream?

@fgdfgdfg it requires a Multicast compatible router/hub and is only currently available on the Openreach network if you are a BT/EE TV customer because the GEA (Generic Ethernet Access Multicast product is a BT Wholesale product who BT/EE effectively by their package from. Sky don't supply BT Wholesales TV product which is fundamentally why it isn't available. Tbh, it's all a ball ache but it's because of how BT are structured and buy and sell their products. 

The new MAUD system is a BT product that is provided to Openreach on a customer basis. It's slowly gaining more traction though and Sky do have plans to expand it to other channels at some point.

MAUD reduces lag down to a similar level as satellite delivery.

Interesting thread. I had a look at the BT article on MAUD. As someone thinking of switching from an ageing Sky HD  box (over 15 years old) to Stream, the big question for me is how it will cope with streaming demand for major sporting events on BBC and ITV, like last year's Euros football and the World Cup next summer. Did anyone experience any streaming issues last year when watching the England games in particular?

ITV aren't currently using MAUD for delivery and the BBC are only trialling it on selected iPlayer broadcasts... 

Personally, I don't think the capacity is there yet at BT's end so in effect it's still really in a trial phase...

Ok let's simplify it a little. BT/EE use multicast to stream their channels. With that, in effect, you "join" the stream as it's "broadcast", so everybody receives the same packets or picture, (110 people will get the same stream). Sky, and other streaming services, use unicast. With that you "request" a stream from the server, everybody will get different "packets" so you will always get a delay (100 people will get 100 seperate streams). This way your next door neighbour will be either in front or behind the picture your receiving as the server deals with every request. With multicast your next door neighbour will be getting exactly the same picture. So with unicast there will always be a delay because that is the way the system is used, there's just no avoiding it


A very concise explanation, Interesting.

It's astonishing the World Cup is round the corner and the Sky Stream delay isn't resolved.  Hope all the Sky Stream customers are ready to hear their neighbours cheering a minute or two before you see England score a goal...

@fgdfgdfg There will always be a longer delay streaming over the internet that traditional broadcasting methods. However its possible for broadcasters to have lower latency streams which significantly reduces that delay down to several seconds, but its down to broadcaster to invest in the technologically ( and it does come at a higher cost). Sky, for example, does offer a low-latency version of Sky Sports Main Event, so all sporting events broadcast on that channel can be watched with a significantly smaller delay ( if you are watching on the low-latency version of the channel, of course).

 

When it comes to the world cup and streaming, unless BBC and ITV decide to utilise the technology for their broadcasts, then yes there will a longer delay for those games when watching via streaming.

You are of course assuming England actually manage to score a flipping goal. 😁

@fgdfgdfg the technology is available for broadcasters to use for IP distribution that will reduce lag to a comparable level to a satellite broadcast. 

Sky aren't broadcasting the World Cup so it will be up to the BBC & ITV to request access to the MAUD technology from BT for their channels.

Sky do already use MAUD on Sky Sports Main Event under the Live Sync option.

Sky stream includes the delayed BBC and ITV channels.
