| Bluetooth feature in RDK | Feature Descriptions |
|---|---|
| Audio Output Sources | Bluetooth audio may be different than HDMI audio (e.g. secondary audio program, application sourced audio such as Pandora, voice navigation audio, etc). |
| Audio Output Routing | Detail PCM audio routing to Bluetooth A2DP SRC, It uses H/W accelerations, S/W processing, RMF involvement on streaming audio/video contents. |
| Audio Encoding | Detail SBC (sub-band coding) and aptX encoding (Bluetooth chip, in software, or in SoC hardware). |
| Audio Output Muting | The Bluetooth audio output may be muted independently of other audio outputs (e.g. HDMI) |
| Audio Input (Settop as AD2P SNK) | Using RDK device speakers over bluetooth i.e transmitting audio input back to a speaker connected with RDK device. |
| Audio Output Routing | Detail PCM audio routing to Bluetooth A2DP SRC, It uses H/W accelerations, S/W processing, RMF involvement on streaming audio/video contents. |
| Audio Output Sources | Bluetooth audio may be different than HDMI audio (e.g. secondary audio program, application sourced audio such as Pandora, voice navigation audio, etc). |
| Dual Decode | Supports ability to simultaneously output one audio stream to HDMI and a different audio stream to Bluetooth |
| Power Control | In future, the power state of each Bluetooth connected device and the Bluetooth subsystem can be controlled |
| Audio/Video Remote Control Profile (AVRCP) | Controller (Remote Control) sends mute and volume commands to target. AV/C commands are defined by the 1394 trade association |

Bluetooth Architecture
Bluetooth Manager and Bluetooth HAL [BTRCore] is that Bluetooth Manager implements the BT HAL [BTRCore] API. Then BT HAL [BTRCore] integrates and manages the BlueZ stack though the D-BUS interface.
