Nameless 11483_50 - It is the 4K channel test name. Refer the 4K testing thread.
TV=>Radio - They changed the slot from a TV slot to Radio slot
Video 481=>0 - They removed the Video ID
Type => ISO13818 - Don't know
Now 4K users cannot see the 4K channel video in their STB.
What cheating? Anyone confirmed that they are not going to show video anymore?
By the way I just checked in my HD STB where I cannot see video even though they are showing video. Only 4K users can confirm if they are getting video or not.
Also, they are testing something by changing the channel parameters. The video will be back soon. You remember or not? After launching 4K STB, the channel showed unsubscribed error for some time on one day and later got activated again. They recently removed the encryption for this channel. Which means? They are doing some background activity which will mostly be a temporary testing activity and the channel will back to normal again.
