HYPERHDR & BACKENDSHDR
For the system to work, it is important that the order of installation be respected.
Installation of PicCap
First of all, it is recommended to start with a clean installation.
– Remove PicCap if it was installed then restart the TV.
Install PicCap via the Homebrew channel or the webos manager application* then
enter the interface via the TV
– Select a ‘backend’ (Old TV or New 2020+), check ‘Autostart’ and click on
‘Reboot TV’ this manipulation will generate the config.json and the Autostart.
We will come back to the PicCap configuration later.
To facilitate the installation, we use the program Device Manager for Webos
which will allow us to install the .ipk from our PC.
For Windows :
https://github.com/webosbrew/dev-manager-desktop/releases/download/v1.5.2
/webos-dev-manager.1.5.2.exe
For MacOs :
https://github.com/webosbrew/dev-manager-desktop/releases/download/v1.5.2
/webos-dev-manager-1.5.2.dmg
Using Device Manager for Webos:
– Start the program.
– In the left menu, select +Add Device.
– Fill in the connection options:
If you have not changed the default login information you should fill in the
information as above.
You will have understood that TV IP ADDRESS is to be replaced by the IP
address of your TV.
– On the main program page we use the Install button in the upper right
corner, to install the necessary .ipk.
Download the necessary ipk :
HyperHDR :

BackendsHDR :
https://www.dropbox.com/s/w2wjh2rmx9met6t/BackendsHDR.ipk?dl=0
Once you have downloaded the 2 .ipk files, install them with Device Manager for Webos but do not launch them.
– HyperHDR :
– From your TV, go to the applications menu and launch HyperHDR
– Install Autostart
Currently a bug will force you to deactivate, reactivate the autostart even if
visually you see it activated.
Restart your TV.
– BackendsHDR
– In the same way as for hyperHDR, go back to the application menu of your TV
and launch BackendsHDR.
We will modify the backends and install a LUT to correct the dark image effect
present on the HyperHDR preview.
After each action, you will be notified of the successful completion of the
operation in the lower left corner of your screen
– To replace the backends, stop PicCap capture by selecting option 1.
– Replace the backends by selecting option 2.
– In the same way we install the LUT, option 3.
– Restart your TV by clicking on option 4.
After restarting your TV you can remove the BackendsHDR app (optional)
Configuration of PicCap
By default we have enabled the automatic recognition of the backend and
HyperHDR should already be able to capture the image.
The automatic recognition will check on your TV if ‘libvtcapture’ is present,
if not, it will automatically switch to ‘libdile_vt’.
On some TVs both backends can work, by default it will always be
‘libvtcapture’ that will be installed. If you have problems with
‘libvtcapture’ you can always test ‘libdile_vt’ by replacing it manually in
the config.json.
In order to modify the config.json file, you will need to use an SFTP client
such as WinSCP.
– Access the folder containing the backends and the config.json by connecting
to your TV.
Edit the config.json file using a text editor such as Notepad++
REBOOT YOUR TV AFTER EACH CHANGE IN THE FILE TO RESTART PICCAP
It may happen that the Autostart file is not generated. If this happens, you
can create a symbolic link by executing
the 2 commands below in ssh : chmod +x
/media/developer/apps/usr/palm/services/org.webosbrew.piccap.service/piccapautostart
ln -s
/media/developer/apps/usr/palm/services/org.webosbrew.piccap.service/piccapautostart
/var/lib/webosbrew/init.d/piccapautostart
Finish by rebooting the TV, the Autostart should now work.
HDR Correction
– Via your internet browser, access HyperHDR by typing ‘the IP address of your
TV: 8090‘.
– In the left menu click
on the preview. – The preview opens in a Popup, click on Live Video.
– On your TV, choose an HDR or DV channel and check
if the preview image is darker than the TV image
– If the images are similar, you won’t need to enable tone mapping, which uses
the LUT to correct color and brightness.
Example not requiring tone mapping:
Example requiring
tone mapping:
If you are in the case where tone mapping is required, go to the left menu of
HyperHDR section Advanced/Network Services
– In the FlatBuffers Server window check the ‘HDR to SDR Tone
Mapping’ box
– Once the box is checked you can choose to leave Fullscreen or to switch to
Light
– This option only affects the HyperHDR preview.
– If you are on an SDR channel when you check the tone mapping box, it will be
necessary to go to the ‘Remote Control’ tab and deactivate ‘HDR (global)’.
– Don’t forget to save the settings.
Restart the TV so that the mode synchronizes
Configuration of the LEDS.
– If you are using Wled on an ESP, it is important NOT to CHOOSE the Wled mode
in the control panel.
– The TV will not handle this process properly, it will make your wifi network
unstable and your TV will enter a reboot loop.
– Use UDPRAW mode with port 19446.
ESP connection and Wled configuration:
