HDMI through Network

[wazza88]

Hi everyone i've been looking for something that allow me to create an HDMI network... to be able to watch the same hdmi signal on various tv's.... thanks in advice

You could try a HDMI splitter. You could use a powered HDMI splitter to have more outputs. Here's a 8X HDMI splitter from Mono Price: http://www.monoprice.com/products/product.asp?c_id=101&cp_id=10113&cs_id=1011301&p_id=...seq=1&format=2

There are others there if you need a few less outputs.

HDMI is uncompressed RGB or YCbCr.

It is not networkable for maybe 7 years.

Explain in more detail what you want to do.

Note that most devices that output HDMI require HDCP. HDCP rules specifically prohibit splitting the signal. And any device that connects to an HDCP protected HDMI port has to negotiate the encryption protocol so one device cannot watch another devices encrypted stream, even if you do manage to split the signal.

I do agree with redwudz that point to point oneway split streaming is possible but this is not networking.

[jagabo]

Nevermind.

i want to have the same hdmi signal i watch on my living room on any other room of my house....

suppose im watching a movie and my brothers want to watch it on their room to.... i found this http://www.amazon.com/Sabrent-Extension-Extender-adapter-200-Feet/dp/B001PT1A7C adapter but i dont know if this would work if i connect each cable to a ethernet switch or router..

Nothing to do with networking. You are off the net and doing data stream splitting. This network tweak level.

You will still need an active splitter like the one linked to by redwudz. It will renegotiate an HDCP link to each connected device.

so there is no way to multiply the output of the sabrent even if i handle every out on separate ethernet switches?

That has nothing to do with what you asked.

Sorry, support fatigue ... go on

[jagabo]

The Sabrent device is the active splitter.

A google search for HDMI over IP will show you devices that will let you network HDMI over an Ethernet LAN switch to as many screens as you desire.

That product would assume a point to point connection. The data is RF modulated onto a dedicated CAT 5/6 path but is not compatible with an Ethernet network. If the source is HDCP enabled (e.g. cable/SAT box, Blu-Ray player, etc.) only one point to point connection is allowed. Without HDCP authentication, the source simply refuses to send data.

I guess I should have provided a direct link:

The devices there are completely compatible with an Ethernet network, are HDCP compliant, and will do what the OP was asking for.

Full disclosure - I do have an interest in the company and products I've referenced. Just trying to be helpful and answer the question.

"Completely compatible with an Ethernet network" is not the same as Ethernet. It means a managed switch can route the point to point modulated RF signal through a wired network but in isolation from the Ethernet network. Dedicated physical CAT 5/6 cables are required. These cables would be isolated from the Ethernet network by the managed switch. In other words, the same cable can't be used for Ethernet and modulated HDMI RF at the same time.

[Nded]

The HDMI over IP devices are not modulated RF. The Transmitters encode the the HDMI signal to TCP/IP packets, the Receivers decode the IP packets back to HDMI. The same single CATx cable can be used for for Internet and other typical LAN traffic, but sometimes the IGMP Multicast (point-to-MANY not point-to-POINT) from the JAP Transmitter often slows down other devices on cheaper network switches, which is why a Managed Ethernet switch is suggested (the Dell 3524 for around $350 is a popular choice). We've even used Wireless Access Points to send the HDMI over IP signal, it is Ethernet. A single CATx cable with 2 compatible switches on each end could easily handle all of the Internet traffic and multiple HDMI sources/screens simultaneously when configured properly.

OK a different technology.

So, how is HDCP handled?

LAN Bandwidth: 300Mbps for 1080p

That would be ~10x compression vs uncompressed SMPTE 292M/372M over coax.

So we're talking $350 for the transmitter and $300 for each receiver?

Answers that will probably just raise more questions (we're used to this after 2 years on the market with HD over IP).

HDCP - The Just Add Power devices are HDCP compliant. In a nutshell, the Transmitter respects HDCP and provides a valid key. Then the HDCP content is sent across the LAN in an encrypted format. It is impossible to watch the content on a PC with a LAN client. Whenever the HDCP required flag is activated the Receivers ask the attached displays for their key. The Receivers have an HDCP validation chip that is listed with DCP labs. If the attached display has a valid key, the content is delivered. If the display does not have a key, the content is denied. A desirable side effect is that we are able to show HDCP protected content on virtually unlimited displays as long as they have valid keys. The content is only delivered to secure "sinks" and is not exposed to any copy protection risks.

Compression - our 1G models use JPEG to fit the content onto a 10/100 LAN. This CODEC is apparent in still text as some small artifacts. It is not noticeable on motion content. The 2G models work best on GB networks. In side-by-side comparisons at trade shows (CEDIA, INFOCOMM, CES, EHX) we show 1G, 2G, and direct to a Blu-Ray. When we ask professional AV installers to choose which screen is "direct" and which one is sent through "2G", about 50% guess the wrong screen. The more economical 1G solution has been well received in a wide range of residential and commercial applications. The 2G solution is demanded by high end enthusiasts (people with $10K Plasmas and $40K+ projectors). We have installations ranging from houses, to sports bars, restaurants, airports, factories, hospitals, and sports stadiums. It is really fun to watch a network with 12 DirecTV boxes sending HDMI to 60+ screens.

Prices - those are the MSRP for the 1G devices. The value proposition is based on the needs and desires of the end users. It is not a good fit for some users, other users and markets find the products to be very affordable. Just like cars, they come in all price ranges and feature sets.

I apologize if this comes across as a self serving post. I just wanted to answer the OP with information that was not in the hands of those who posted earlier.
