Management of dynamic PMT

Hello,
I am building a DVB-T TV player, with Exoplayer.
I recently discovered how some TV channels, like Canal+, proceed to be in clear mode at some time and in crypted mode at other time.
Actually, the stream PIDs in the PMT are changing, (but the PMT's PID remains the same).
The problem is that my DVB scan is static, and when I try to watch this channel, I would need to retrieve the PMT content from Exoplayer, to adjust the stream PID that I filter from my tuner.
Is there a way to retrieve the stream PIDs from the PMT with Exoplayer ?

Best regards,

Thibaut
