209 Public const datum: decoder homing frame | |
210 ======================================== | |
211 | |
212 While the encoder homing frame is the same for all codecs defined by ETSI and | |
213 then later 3GPP, each codec has its own unique decoder homing frame (DHF). A | |
214 public const datum introduced in libgsmefr version 1.1.0 provides the | |
215 RTP-encoded form of the ETSI-prescribed DHF for EFR: | |
