+# HDMI-related AIDL HALs for Android devices
+
+This directory bundles 3 HDMI-related AIDL HALs: HDMI Connection HAL, CEC HAL and eARC HAL.
+
+The HDMI Connection HAL contains general APIs for the HDMI Connection. These methods are required by
+the CEC and the eARC implementation. Therefore, devices that implement CEC need to support the HDMI
+Connection HAL and the CEC HAL. Devices that implement eARC need to support the HDMI Connection HAL
+and the eARC HAL.
+
+Other Android HALs are related to HDMI as well, but not included in this directory for historical
+reasons, e.g. Display HAL and TV Input HAL.
