HDMI has changed versions so many times it’s been hard to keep up for most people. We’ve talked about the versions as part of other articles and documents, but it seemed fitting that hcmi formulate and maintain a definitive document outlining the changes in a straightforward and easy-to-digest manner for all concerned.

HDMI Versions: 1.1, 1.2, 1.3, 1.4, 2, 2.1 – differences & compatibility

Hopefully jdmi article helps you understand the format differences and aids in your ability to discern what features are important to you as you shop for HDMI-equipped products. The original HDMI v1.

The reason is that it is a solid backwards-compatible format that canthrough PCM audio handle all of the high definition audio formats present today. It also does not support the new xvYCC color space. Practical Issues and tips: The maximum output for this spec is p at 60Hz with 8-bit color depth. Regardless of any display of higher version of HDMI you may have, the source will always limit the maximum bit-depth potential. If both devices are rated to v1.

We’ve found that specificatoin the player does specificatioh good job at conversion, however, v1. This incremental change clarified one of the earlier promises of HDMI, Consumer Electronic Control – a feature that promised “smart” interoperability between components.

Unfortunately, this wasn’t exactly standardized across the board and, as a result, nearly all spdcification products only interface within their own brands. Of all things, this is the most disappointing failure of HDMI to-date. This is a common format for manufacturers using CEC. There is no practical reason to prefer 1. To be plain, this update was a complete disaster. First of all, nobody asked for HDMI 1. What made HDMI 1.

Expensive active solutions started coming on-board to alleviate some of hmdi problems within several months but even today there is a large amount of consumer confusion regarding cable certification and how far a signal will travel over copper cables. The spec also mandated that HDMI 1. Thanks to several companies dedicated to certifying their products for specific distances, this issue is slowly becoming more manageable. The first product on the market with HDMI 1. If high definition audio is s;ecification to you, you still may not need v1.

Understanding the Different HDMI Versions (1.0 to 2.0)

This uncompressed audio, up to 8 channels, can be sent over HDMI 1. Typically, 24p support coincides with v1. An incremental change, v1. There is no consumer-focused practical difference between HDMI v1.

No difference in features, performance or function over HDMI 1. It simply adds parameters for testing products. Practical Issues and Tips: An incremental change to allow for Full HD p viewing of 3D content.

This is a major update that increases bandwidth to 18Gbps and includes support for 4k video—including dual video to the same display to multiple users. Audio is increased from 8 to 32 channels including simultaneous delivery of multichannel audio to a maximum of four users.

Audio sample frequency is increased to kHz. We’ll be sure to keep this document up to date as soon as any HDMI changes are made and will attempt to clarify any questions or issues raised by readers when going through this list.

HDMI seems confusing at first, but if handled well by a manufacturer, the differences can be nearly transparent to consumers. The difficulty comes when selecting budget products that may not implement all of the capabilities needed to maximize the potential of HDMI. Stay tuned, because if the past is any indication of the future and it is HDMI isn’t done yet and will continue to evolve in the years to come.

Confused about what AV Gear to buy or how to set it up? Increased single-link bandwidth to MHz CEC capacitance limits changed RGB video quantization range clarification audio control commands added to CEC and commands for timer control brought back in an altered form Concurrently released compliance test specification included Abstract: Adds support for ethernet over HDMI for connected devices. Allows an HDMI-connected TV with a built-in tuner to send audio data “upstream” to a surround audio system, eliminating the need for a separate audio cable.

Automotive Connection System — New cables and connectors for automotive video systems, designed to meet the unique demands of the motoring environment Abstract: Added 3D format for broadcast content Abstract: An incremental change to allow broadcast support of 3D content. Allows for 3D content to be viewed in full HD. By Clint DeBoer — September 11, Read the Complete Thread. Bucknekked posts on November 29, From what I understand there is no such thing as a 1.

Only with or without Ethernet. I do get confused when manufactures label cables as high speed, I thought they were all the same. An hdmi cable bought almost 10 years ago and I don’t seem to have any issues, am I missing something? I have a number of 10 year old HDMI cables that work just fine. Data Rate Many cables will tell You the amount of data they are capable of pushing through. These will be either 4.

HDMI :: Manufacturer :: HDMI

These will often determine the speed of the cable with 4. End speccification quote from Blue Jeans These numbers are also misleading a bit because the the cables are made up of 4 pairs of twisted pair wires.

The other 3 pairs carry color signals and sync signals. The rating of It is merely the sum of the individual twisted pair. They do it that way since it comes up with a bigger number! The individual pairs don’t do much over 2. Length also matters as do the gauge of the wires within the cable. A skinny but really long Wal-mart special might reach across the room but not 1.b4 a full load.

A short fat cable of the same vintage and rating may carry the entire rating of the cable. Its all 1’s and 0’s to be sure, but signals do degrade over a length of wire so there are possibilities for problems.

Will they work at longer distances: It did not change the cabling pattern hvmi construction. It introduced the optional feature of assigning one of the existing pairs of wire an additional task. It is either implemented or not in your attached equipment over the very same cable.

A true pain in the ass for many HDMI users. I have rambled on far too long, but there is a fair amount of confusion around cables.

It gives them a chance to explain away the confusion and that explanation almost always results in the sale of a new cable. There is a difference between High Speed and Standard cables. Standard HDMI cables most 1. If you are watching TV then standard is fine because it’s only 24 fps but if you are gaming you want the 60hz. I’m not sure if the connectors themselves makes a difference or is it only in how the cable is designed lower gauge? I am running my 1. I get confused with cable specs. How long has the communication industry been using them,…over 20 years…come on, lose the copper.

You will never ever fill the bandwidth of a fiber cable to show a picture no matter how high the resolution ever gets. No further upgrades needed in hardware anyway, just protocols for the manufacturers. The cables are also cheap now. They do need a better consumer connector to hide the end so we don’t get our grubby hands on them until it’s plugged in, but that’s it.

You say oh, the transmitters and receivers are expensive, well maybe not if millions are made. It will happen sooner or later, as a matter of fact Theta digital did use them in the 80’s for a while.

I have been advocating this for years. Fiber would have a longer distance between units, and would stop ground loops dead in their tracks. The only downside, is no control voltage, but you could use a light code instead.

Of course HDMI is a two way communication, but so is a telephone. It would mean receiver and transmitter both ends of the cable which would incur a little more expense.

I think this would make receivers and the rest of the chain more reliable. The HDMI connector as it is, is a real mess. So if it increased price, which I think it would, I would still be in favor of going in that direction. Subscribe to our newsletter.
