What is an IRD?
A6. An IRD is an Integrated Receiver Decoder (also known as a set-top box). The IRD takes the digitally encoded (either securely or non-securely) content that has been received by the Downlink facility and converts it to a signal format that the TV is capable of displaying. AT&T employs IRDs that utilize the Digital Encryption Standard (DES) for secure transmissions. AT&T can design solutions with additional security if requested.
