To get the channels scanned into TVHeadend is pretty simple. Assuming you have already read my post on setting up Malaysia FTA DVB-T2 channels, the steps are similar. Define, new network by going to tab Configuration->DVB Inputs->Networks. Now enter appropriate datas as per screenshot below.
Nothing much to config here. You can actually fill in with anything you like. This is just to organise channels according to their respective providers. Don't forget to link these networks to correct tuner. Go to Configuration->DVB Inputs->TVadapters, enable the tuner and link the 2 networks.
The important data is in the next step in tab Configuration->DVB Inputs->Muxes. Add these 2 Muxes to the config and voila!.. All other muxes (for astro) will automatically appear. Note that there is only one mux for K-Vision carrying all 40 services. While Astro runs 437 services on 29 muxes. Below are the setup to add.
Remember to select correct Network when adding new mux..
Note that Astro runs on DVB-S2
While K-Vision is on DVB-S
Once the services are populated, (and you have VLC installed), you can test-play the channel by clicking on the play button on the far left column.
