First of all, hello you all.

I have 2 ideas I want to do.

1)
Modify the behaviour of enigma2 to simulate the channel navigation of a skybox.
Specifically I want the UP/DOWN arrow to show a lightpanel (not the channel list) and allow for channel switching (this already exists via some plugin)
I also want to add the ability to move (LEFT/RIGHT) along the EPG.
I suppose this all can be done via a python plugin. Am I correct?

2) (this is harder...)
I want some sort of permanent timeshift that adds a user configurable delay (say 500/1000 ms).
But i want this timeshift to behave very differently from usual timeshift.
When looking at a crypted stream, timeshift decodes the data as soon as it arrives, and stores the decrypted data.
I want the new timeshift to introduce a gap between audio+video stream and ecm stream.
The goal for this is to have the ecm decoded before they're really needed.
Let me explain better with an example.

a) Data arrives
b ) audio+video is separated from ecm
c) audio+video is delayed by 1000ms
d) ecm is sent immediately to the camd.socket
e) enigma2 makes a buffer of last cam's results, and knows the gap between the audio+video and the ecm
f) when the delay ( c ) is over, audio+video is played
g) at the same time, the result of the correct ecm is sent to the ca

by decoupling audio+video and ecm you're allowing a longer time for the card to decode the ecm
This will allow slow cards to be on time.

Any suggestion of how to correctly do this?

Thanks,
manuele

For 1 I think you can use a python plugin, interfacing with the InfoBar or InfoBar generics screen and using a solution like in quick button for overwritting the functions.
For up/down is this not just a skin change that is needed?

For 2, I am not sure I guess looking at the permanent timeshift plugin would help, for change other things about how the process is done, you may need to change the native layer and for this I think you need to look at the files in lib/service
