Firstly, the full form of SCMS is Serial Copy Management System. You may get a bit of an idea from the full form. It is a copy protection scheme created to prevent DAT (digital audio tape) recorders from making second-generation or serial copies. Now you may wonder what SCMS-T is. This is also a content protection method created to protect the contents transmitted on Bluetooth wireless technology. It automatically rejects the contents that are previously, by default, protected by the same method.
Basically, SCMS sets a copy bit in all the copies, which acts as a barrier for anyone who tries to make further copies of those first original copies. However, it does not limit the number of first-generation copies.
The use of SCMS was not overvalued in the wireless industry as it was not very useful in other wireless connections like satellite connections and wi-fi. Thus, it was limited to Bluetooth connectivity only. The copy protection tool looks for some bits in the subcode data. There are usually three states or three types in these bits: copy once, copy allowed, and copy prohibited. Now from the names, you can make out what it means.

Thus SCMS-T is an important tool that can be used for content protection via wireless networks and devices.

CSR Harmony uses the SCMS-T method for digital rights management to protect your content or someone’s content that is being played, used, or transferred. CSR Harmony’s SCMS-T method is only compatible with devices that use SCMS-T copy protection. If you are using a device like a headset or any other audio device without the SCMS support, you will not be able to connect or stream the content.
