Note: Media Profiles is a function that is applicable to Cable mode only.
To create a media profile:
- From the Policy Server section of the navigation pane, select Media Profiles.
The content tree displays the Media Profiles group.
- Select the Media Profiles group.
The Media Profile Administration page opens in the work area, listing available media profiles.
- Click Create Media Profile.
The New Media Profile page opens.
- Enter the following information:
- Codec Name — Unique media subtype assigned to the media profile.
This is defined in the IANA MIME registration for the CODEC. Enter a string of up to 255 characters.
- Transport Type — Select from the following:
- Payload Number — The payload number.
- Sample Rate (kHz) — The sampling rate of the CODEC in KHz.
The valid range is an integer from 1 through 100 KHz.
- Frame Size in Milliseconds — The size of one audio frame in milliseconds.
This is the length of time represented by one audio frame. A single RTP packet may contain multiple audio frames. The bitrate is calculated using the frame size in milliseconds, the frame size in bytes, and the packetization time. The valid range is 0 through 100 ms.
- Frame Size in Bytes — The size of one audio frame size in bytes.
This is the size represented by one audio frame. A single RTP packet may contain multiple audio frames. The bitrate is calculated using the frame size in milliseconds, the frame size in bytes, and the packetization time. The valid range is 1 through 1,500 bytes.
- Packetization Time — The length of time, in milliseconds, represented by the media in a packet.
The bitrate is calculated using the frame size in milliseconds, the frame size in bytes, and the packetization time. The valid range is 1 through 100.
- Always Use Default Ptime — Select to always use the default packetization time, ignoring the value received in the SDP message.
The default is unchecked.
- Click Save.
The media profile is created.
