Yes, it is possible, as shown above.
The process is the same as when you activate TSReader, TransEdit, or VLC from Crazyscan.

AltDVB does the same thing, only TSR reacts a little slower than TransEdit or VLC, and it decodes the stream, not the player.

One of the new features of this version of AltDVB is that it has integrated other applications, such as those mentioned above, which can be used through the player.

The next version of AltDVB will also include a blindscan, similar to Crazyscan. With this, we can say that the player will serve as a kind of "portal" for functions beyond the usual TV or listening to radio services, as intended by most DVB players.

AltDVB: Streaming 224.5.6.7 : 1234
-s TSReader_UDPMulticast {IP} {PORT}

Unicast settings:
AltDVB: Streaming 127.0.0.1 : 1234
-s TSReader_UDPUnicast {PORT} 127.0.0.1

Sometimes the video stream (display thumbnail) appears in the TSReader window, in which case it can be started and played directly.
