126 AAC ADTS

AAC over RTP

As there is no standard for AAC in RTP yet, the format depends on the vendor. Two

major formats of AAC encapsulation are used on the network: RAW and ADTS.

Streaming Client is capable to decode RTP with AAC encapsulated in ADTS. Set your

AAC encoder device to:

• payload type 126

• AAC encapsulated in ADTS format; RAW is not supported

Both PS (parametric stereo) and SBR (spectral band replication) are supported in

AAC/AAC+ decoding.
