Default Optimum setting for streaming HD video

I am having a heck of a time being able to stream HD Video wirelessly from an HD Home Run Prime (a networked cable tuner made by Silicon Dust) to a PC mounted on the wall about 40ft away.

Purchased a WNDR4000 as well as N600 Dual Band USB Adapter yesterday and want to know the best way to set up this router/USB Adapter combination to enable HD video streaming without pixelation and interference.

Can someone offer advice on network settings on the WNDR400 and N600 to give me the best setup for streaming video. I am a networking novice so please bear that in mind when using Acronyms

Thanks in advance.
Marc

Make sure all your wireless adapters are N capable and use WPA2-AES encryption.

You won't get reliable streaming of hd wirelessly. Sd video yes, but he no. Check avsforum.com in the streaming sub forum for lots of info. I forget what it's called but the next standard beyond. Should stream hd but n will not.

Well that's not true. I stream 1080P effortlessly through my WNDR3400 wirelessly. Comcast 15Mbps tier but only need about 5-8Mbps for this. Works fine.

You actuall only need 5-6 mb stream for 1080 and Dolby Digital. This router is very capable. I do it all the time.

Sabretootyh and Charlie C,

I can stream ok in HD but pixelation comes in and out every now and then. I'm using the 5Ghz band only for the stream. The only PC on the 5Ghz band is the one i want to stream HD video to. I have no neighbors close enough to me to be on a 5Ghz band that could interfere.

Are there any settings I should pay particular attention to in order to maximize the HD stream? Either on the Router side or the USB dual band receiver on the PC I have. Please advise.

Thanks,

Marc

Have you tried the 2.4 band?? That's what I'm using.

Marc's experience is what folks generally experience, streaming almost works with some pixelation, stuttering etc . SOme special case setups will work. If you have one that works flawless then congratulations.
Best,
Jeff

I steam VUDU 1080 full DD sound perfectly on the 5GH band. Router is
upstairs on other side of home. Test reveals a solid 10-11 mb stream.
No pixaliation ever.

Default Re: Optimum setting for streaming HD video

from the vudu website, here's the transfer speeds they claim you need to make their service work:
SD (480p) requires 1000 kbps
HD (720p) requires 2250 kbps
HDX (1080p) requires 4500 kbps

The HD 720p stream is far from full uncompressed HD. Running the VUDU test from my wireless b laptop shows basically what any speedtest shows about my internet connection, 4.6mbps down and 0.65 mbsp up. I cannot stream without out stuttering any HD video.
From the wiki, here're true bit rates required for video with audio encoding:

3.5 Mbit/s typ - Standard-definition television quality (with bit-rate reduction from MPEG-2 compression)
9.8 Mbit/s max DVD (using MPEG2 compression)[17]
8 to 15 Mbit/s typ HDTV quality (with bit-rate reduction from MPEG-4 AVC compression)
19 Mbit/s approximate - HDV 720p (using MPEG2 compression)[18]
24 Mbit/s max - AVCHD (using MPEG4 AVC compression)[19]
25 Mbit/s approximate - HDV 1080i (using MPEG2 compression)[18]
29.4 Mbit/s max HD DVD
40 Mbit/s max Blu-ray Disc (using MPEG2, AVC or VC-1 compression)[20]

VUDU is delivering compressed video and lossy compressed audio. So is netflix. If you rip blu-ray to a full 1080p format and store on a NAS on your LAN (this is the best case for testing streaming) and try and stream it wirelessly, you cannot do it reliably at the necessary bit rates. If it works, you're streaming a compressed format. 9Mbit/sec is not true 1080p.
