Steve Casner (CISCO)
for
A. Crossman (PictureTel)

2. Overview ITU-T standard approved in Sept. 1999 Wideband 50Hz - 7kHz
Two rates: 24kbit/s or 32kbit/s
Low complexity, < 15MIPS
20ms frames (60 or 80 octets/frame)
Quality equivalent to ITU-T G.722

3. Mapping G.722.1 into RTP Octets
sequence (for one frame) of bits (480 or 640) output by encoder
msb… lsb
RTP octet 1
RTP octet 2
RTP octet 3
RTP octet 60 or 80
first bit
transmitted
last bit

4. RTP Payload Format
