Object manipulation chain

Question

in my application I have three interfaces ICapture<T>, IDecoder<T, K>and IBroadcaster<K>.

Now I implement, for example, a class VideoCapturethat inherits from Capture<IntPtr>(IntPtr is the raw data created by the class). When data is generated by an object VideoCapture, I first want to decode it from Tto K, and then translate it.

I want to know how you would relate this? Just by writing a method like

var data = videoCapture.GetData();
var decoded = decoder.Decode(data);
broadcaster.Broadcast(decoded);

Or are there any design patterns I could use? I know the chain of responsibility. I could imagine classes like CaptureHandler, DecoderHandlerand BroadcastHandler, inheriting from HandlerBase. HandlerBasewill provide mechanisms for passing objects to the next handler.

var handler1 = new CaptureHandler();
var handler2 = new DecodeHandler();
handler1.SetNext(handler2);
handler1.Handle(object);
