About Media Profiles

Note: Media Profiles is a function that is applicable to Cable mode only.

A media profile describes a CODEC supported for Rx-to-PCMM translation. The MPE device includes a predefined set of media profiles, and you can create new RTP (real-time transport protocol) profiles. After you have defined a media profile in the CMP system, it is automatically deployed to MPE devices.

Media profiles are named codec_name-transport_type-sample_rate. Media profiles are mapped to CODECs based on the information received in a session description protocol (SDP) message.

In defining a media profile in the CMP system, you specify its name, transport type, sample rate, frame size (in both milliseconds and bytes), and packetization time.

Note: You cannot create media profiles for the UDPTL or UDP transport types.

Predefined Media Profiles describes the predefined media profiles.
