IWRL6432 Enables Smart TVs

As television have grown in size, gone slimmer and increased the variety of content which can be played, little so far was done to make them truly smart.

IWRL6432, which enables to:

1. detect presence of spectator(s) in the room
2. count them (up to 5)
3. detect their location in the the room
4. classify the humans vs non-humans motion

Allows truly smart-TVs which can bring a lot of energy savings and ease of use for the end customer:

• switch the video stream OFF if no one is in the room (and switch it back ON when the enter the room).
• switch the television OFF if no one has been in the room for a set time.
• reduce streaming bandwidth if all spectators are too far from the screen (which saves decoding energy and overall energy in the operator infrastructure).
• enable all of the above based only on human presence and ignoring pets or vacuum robots presence.

Besides those,?IWRL6432?also enables:

5. Gestures recognition

Which in turn brings the benefit for smart-TV viewers to change channels, volume or other settings should the remote control not be available.

Lastly,?IWRL6432?also enables:

6. breathing rate and sleep detection

which in turn enables smart TVs to have specific profiles should the last spectator in the room to fall asleep in-front of the television: reduced volume, delayed switch-off, ...

Besides smart-TVs,?IWRL6432?brings those features to many similar applications:

• Desktop and laptop monitors
• Conference Room systems
• Wireless and smart speakers and sound bars
• Digital signage for retail.
• and many more
