[GTT/GTC] HOW TO CONFIG BISS KEY

The GTC/GTT now supports 6 different key formats in SoftCam.Key. The search for a matching key is done from the highest priority (tightest test) to the lowest priority (loosest test). Recommended the following ways.

1 - Match key by faulty ecm pid
F <sid><ecm pid> 00 <key>
where

sid (2 bytes) : the service id of the channel
ecm pid (2 bytes) : the ecm pid of the channel only if it's different than '1FFF' (faulty, per BISS specs)
key (8 bytes) : the key (Control Word - CW) with or without the checksum bytes set
Example:

sid : 0002
ecm pid : FEFE
key : 1122334455667788

F 0002FEFE 00 1122334455667788

2 - Match key by audio pid, or video pid, or pmt pid
F <sid><pid> 00 <key>
where

sid (2 bytes) : the service id of the channel
pid (2 bytes) : any other pid of the channel (except the ecm pid) like audio pids, video pid or pmt pid.
key (8 bytes) : the key (Control Word - CW) with or without the checksum bytes set
Example:

sid : 0001
pid : 1020
key : 1122334455667788

F 00011020 00 1122334455667788


3 - Match key by service id alone
F <sid>1FFF 00 <key>
where

sid (2 bytes) : the service id of the channel
1FFF : the default ecmpid for all BISS channels
key (8 bytes) : the key (Control Word - CW) with or without the checksum bytes set
Example:

sid: 0100
key: 1122334455667788

F 01001FFF 00 1122334455667788

BISS key no longer work. Please update DVBPlayer.apk for GTC
