It is rendered to a loudspeaker layout (e.g. 3.1.2ch) or headphones with loudness normalization, and is played back on loudspeakers built into the big-screen TV or headphones connected to the mobile device, respectively. - UC2: Two [=Audio Element=]s (e.g., 5.1.2ch and Stereo) are delivered to a big-screen TV through a unicast network. Both are rendered to the same loudspeaker layout built into the big-screen TV and are mixed. After applying loudness normalization appropriate to the home environment, the [=Rendered Mix Presentation=] is played back on the loudspeakers. -- UC3: Two [=Audio Element=]s (e.g., FOA and Non-diegetic Stereo) are delivered to a Mobile device through a unicast network. FOA is rendered to Binaural (or Stereo) and Non-diegetic is rendered to Stereo. After mixing them, it is processed with loudness normalization and is played back on the headset through the Mobile device. +- UC3: Two [=Audio Element=]s (e.g., FOA and Non-diegetic Stereo) are delivered to a mobile device through a unicast network.
