How to Get an Accurate HDMI Test
The HDMI Test is used to identify the High-bandwidth Digital Video Interface that is in the Information Technology domain. The interface consists of twelve pins, including two power levels and eight DVI connections. It is used to send two different formats of information over the network. There are different Hdmi Test methods and results, which need to be compared for the purpose of finding out whether your video cable is compatible with the Hdmi standards or not.
Most often, people use the Hdmi specifications which are based on the High-Bandwidth Digital Video Interface specifications published by the FCC. However, the truth is that these are not the complete definition of the Hdmi standards. More than that, it also refers to the limit lines that are necessary to support HDCP for HDCP enabled content such as Blu-Ray and High Definition Television broadcasts.
You should use an Hdmi Test to check if the HDMI cable you're using is capable of transmitting HDCP-protected High-Bandwidth Digital Video Content and if it can handle the data rate necessary for your HDTV. The Hdmi test is able to detect the HDMI signal which is sent out by the source device such as a gaming console, digital television or computer. In order to do this, it must measure the amount of bandwidth which is used for sending the video data from the source device to the monitor. The amount of bandwidth is measured in bits/sec. In addition to that, an Hdmi test instrument also checks if there is any interference caused between the HDMI signals from the source device and the audio signals from your TV or monitor.
One of the most common Hdmi Test methods used today is the MMC Test that has been developed to enable owners to check the quality of the data channels which are being transmitted from their HDMI connectors. There are two types of MMC Tests; the hardware MMC Test which relies on a converter box and the software MMC Test which works on the Windows operating system. Both of these tests carry out similar procedures which enable them to check if the data channels are working correctly.
An MMC Test which operates on the Windows platform is named as the Common Mode MMC Test. This is a special type of MMC Test which is commonly installed in consumer electronic appliances such as DVD players and camcorders to check if they work in the DVI mode. It is also used in conjunction with the Analog HDMI Test because the DVI signal which is present in this mode is not identical to the other 81150 signal which is carried by the DVI interface. If the test is successful, the software will prompt you to replace the DVI interface with the other 81150 signal.
There are other types of HDMI compliance test signals which are available for use in HDMI Compliance Test programs. Some of the commonly used are the PCM Test, HMR Test, and the HDMI Reference Signal. These tests ensure that consumer electronics like TV's, DVD players, recorders and other consumer electronics work in accordance with the high definition signals transmitted. The PCM test is the most widely used test signal and the HMR test is mostly used in testing broadcast receivers and satellite transmitters.
Other types of HDMI Compliance Test include the HDMI audio return channel tests. HDMI has two layers; the first layer is also known as the protocol layer and is used to carry the audio information. The second layer is referred to as the audio answer layer and is used to carry the video information along with the audio for display purposes. The audio return channel tests are useful in checking if your TV or DVD player has the capability of decoding the audio signals.
There are a number of ways in which you can obtain an accurate Hdmi analyzer measurement. One way is through buying from a genuine Hdmi interface manufacturer who sells Hdmi analyzers with their Hdmi products. You can also search for a good Hdmi analyzer manufacturer online and then buy one from them after getting a measured Ethernet cable or an HDMI cable from them. A person who has a good knowledge of computer hardware will be able to read the data cable on his own and interpret the data given on it. In order to obtain an accurate measurement, you need to get a pair of analyzers made by the same company.
It is very important to choose an analyzer that has been made to meet the specifications of the HDMI specification. The most popular analyzers in the market are those created by companies like Analog Devices, Analog Premium and Mitel MiSN. Most of these companies have excellent track records and have been in this business for long. The quality and precision of their measurements are guaranteed at all times. It is very important to compare between several companies to choose the one that meets all your requirements.
