Directivo, TivoNET, and ExtractStream

[sjf@c...]

As I understand it, on the stand-alones, if macrovision is detected 
when receiving/recording the signal, a flag is set. Then when playing 
back, if that flag is set, the macrovision signal is generated and 
added to the playback signal. 

For directv, the digital signal must be sent with a flag to determine 
if the receiver is to apply the macrovision signal to the decoded 
analog output. For DirectTivos, that flag must be stored with the 
program, just as with standalones. And when played back, if the flag 
is set, the macrovision signal is added into the analog playback.
