How Much Bandwidth Do You Need for Streaming Video?

Netflix● 1 Mbps for viewing on a laptop computer● 2 Mbps for SD video on a TV● 4 Mbps for 720p HD video● 5 Mbps for "the best video and audio experience" (according to Netflix)

Hulu PlusNote: If a TV show or movie repeatedly needs to buffer, Hulu Plus will stop streaming the video and recommend that you downgrade the video quality.

● 1 Mbps for SD video● 2 Mbps for 720p video● Over 3.2 Mbps for best quality HD video and audio

VuduNote: All Vudu movies are streamed with Dolby Digital Plus 5.1 audio.

● 1.0 - 2.3 Mbps for SD video● 2.3 - 4.5 Mbps for 720p video● 4.5 - 9.0 Mbps for HDX 1080p video● Over 9 Mbps for 3D HD movies

Apple advice for Apple TV

Based on a reasonable business cost model, an ISP cannot afford to size their network to have even 10% of their customers running real-time streaming video at the same time.

----------------------------

If your ISP has 50 megs of incoming bandwidth, then if 40 customers simultaneously run YouTube, the link will be exhausted and all customers will be wishing they had their dial-up back.

In Panama a huge amount of the bandwidth is used on mobile devices

Yesterday one of my coworkers sent 10 photos by whatsapp to the entire group of 15.

Each photo was about 200k, so the 10 photos were about 2 megs of data

2 megs x 15 = 30 megsmine came over the wifi

It’s going to get worse!!!

Roku and Sling TV and USTVnow in conjunction with Netflix, Amazon, Youtube and other services are going to make you wish for your old dial up connection!

We will come to expect that live TV comes over the internet, we will want to ditch the little dish.

So how many simultaneous YouTube Videos can be supported from a 50 megabit Bandwidth?

Live streaming YouTube standard video needs on average about 750kbs , or about 3/4 of

a megabit, in order to run without breaking up.

On a 50 megabit shared link provided by an ISP, in theory you could support about 70

simultaneous YouTube sessions, assuming nothing else is running on the network. In the

real world there would always be background traffic other than YouTube

If you assume that there is some non-video traffic, let’s say 10 megs and assume that

some streaming is attempted at HD then less than 30 users can stream before the

system comes its knees. The more HD the faster the system will buckle.
