Can someone explain what the main differences are between the two?
I'm only concerned about resi or small office environment, so limit of 100 sources for example is not a concern.

Other than one using Coax and the other using category or fiber cabling, what is a real advantage/disadvantage of one vs. another?

Here is what I see:

1. JAP doesn't do interlaced, which is what most of DirecTV stuff is.
2. JAP is little more complicated if sources are not in same location (stacking 500 series switch is required)

1. M3B as no IR.
2. M3B lipsync under certain cases

Seems that M3B has a cost advantage, but sine there is no IR, that needs to be taken into consideration.

Here are the differences (from my point of view).

M3B
Pro's
Uses Coax (New or old)
Uses Coax Splitters for signal Distribution (not expensive Network switches)
Easy Cable termination
Up to 50 sources to an unlimited amount of displays
Small size
Can be powered by USB
Great Price per unit
95% Blu Ray Picture Quality
Moderate System Price
Great Support

M3B
Cons
Only supports PCM 2 channel Audio
Does not return IR commands to source
Takes about 8 seconds to change source

JAP (from what I know)
Pros
256 Sources to unlimited displays
Returns commands to source
Supports Multi Channel Audio
Quick(ish) source change
Great Support

JAP Cons
Requires expensive Network Switch
Requires good quality termination practices
Expensive System Price
Large(ish) unit size

PS: I am sure that I missed Pro's & Cons for both systems, dealer input (for both) is wanted.

Brent, what about audio delay if you break it out to speakers?

And that is why I ask for Dealer input.

Due to the encode/decode process there will be a .75 second delay between the source and the display. This will ONLY be apparent if you break out the audio at the source for separate distribution.

JAP 3G equipment works with interlaced signal. The 2G stuff requires progressive.

How does JAP perform if you break out the audio?

Works fine for me. They have buttons on them to adjust the audio delay. I think you can adjust the audio delay via ip commands as well.

Perfect. On the 3g and 2g+ you can login to adjust for lipsync.

JAP can go from 4000 inputs to 60000 outputs.

JAP can do a 47x 88, then when the customer wants to add more, its very easy and doesn't require and entire system rebuild.

JAP has 2k and 4k in the same system. 4k downscaling to 2k.

Who the f uses interlace? 720p, 1080p, and 2160p.

JAP has CEC, 232, Network and IR over one CAT5.

JAP has image push and image pull. I use this all the time and it is amazing!!!! Best feature ever!!!

JAP has a sku labelled "Flux Capacitor"

JAP switches video in a single frame rate, so 1/25 of a second.

The encoding is so quick that I saw a BluRay split between a display and a JAP system and you couldn't tell which one was what. They both looked identical in timing.

Video Wall built in.

They also have a Tiling Piece.

The JAP stuff is rock solid. I have hundreds in the field and have not had a single failure.

I am sure Ed while chime in :)

vwpower nailed it..

My comments below are just my opinion and in hope Brent learns more about the product.

"JAP Cons
Requires expensive Network Switch
Requires good quality termination practices
Expensive System Price
Large(ish) unit size"

Luxul and Cisco both make affordable swiches that are much lower cost than you think

Any network requires good termination practices. A dealer who cant terminate an RJ45 connectors shouldn't be installing AV gear.

When you are talking a small size system yes JAP is very expensive. Keep in mind though when you add all of the additional features that JAP does there is a cost associated with them and its sometimes easy to let a price tag make you forget about all of the things vwpower listed above.

Im not sure their units would be considered that large. I havnt had any dealers have issues placing them.

What is this image push/pull that you speak of?

So JAP can or cannot do interlaced signals?

You can push (send) a jpeg image to the display for digital signage or slideshows. You can pull (capture) an image from the video display to capture the image.

Can...3G series units.

900+ channels on DirecTV, Dish Network and cable boxes everywhere.

Direct quote: "All HDTV broadcasts are either 1080i or 720p. Most stations, such as CBS, NBC, and others, are 1080i."

Do not forget that in some areas the CATV default rez is 480P for non HD channels.

This is why I brought it up.

I was not aware that 3G did interlaced.

720p was OK with 40-50" TVs, but with 65", 75"+, those pixels get stretched (or scaled) a lot.
