Live (MPEG) Service
The following options are available in the encoding section:
Encoding Settings Options
Video Input
Video Standard
Aspect Ratio
Encoder Profile
Video CODEC
Video Resolution
Video Bitrate
Video Mode
Audio CODEC
Audio Bitrate
Audio Sample Rate
Perform these steps to configure the MPEG multicast stream:
1.
Select Configure Encoder from the MAX Encoder menu. The Live Service page opens (FIG. 64).
2.
Use the Video Input options menu to indicate whether you are connecting to the S-video or composite
port on the MAX encoder.
3.
Use the Video Standard options menu to indicate which video standard the MAX encoder is using.
4.
Use the Aspect Ratio options menu to indicate the aspect ratio you want to use for the multicast stream.
5.
Use the Video Resolution options menu to indicate the video resolution of the multicast stream.
6.
Use the Video Bitrate options menu to indicate the video bitrate of the multicast stream.
7.
Use the Video Mode options menu to indicate the video mode of the multicast stream. It is recommended
that you select CBR.
8.
Use the Audio Bitrate options menu to indicate the audio bitrate of the multicast stream.
9.
Use the Audio Sample Rate options menu to indicate the audio sample rate of the multicast stream.
10.
Click Apply. Clicking Apply saves your configuration.
11.
Click the Enable check box to begin the multicast stream.
With the stream enabled, you cannot change any of the multicast or encoding
parameters.

The MAX encoder supports either S-Video or Composite video inputs.
The MAX encoder supports NTSC (USA and Japan) and PAL (rest of the
world, excluding France) video standards.
The MAX encoder is supports a 4:3 and 16:9 aspect ratio.
2
Vision supports only the MAX Custom encoder profile.
2
Vision supports only MPEG-2 video compression on the MAX encoder.
The MAX encoder supports D1 (720 x 576 PAL / 640 x 480 NTSC) and SIF
(360 x 288 PAL / 320 x 240 NTSC) resolutions.
The MAX encoder supports a range of selected video bitrates from 500 Kbits to
6 Mbits. The recommended encoding bitrate is 6 Mbits.
The MAX encoder supports Constant Bit Rate (CBR) and Variable Bit Rate
(VBR) modes. For multicasting, CBR is recommended as it produces a
constant rate over the network.
2
Vision supports only MP3 audio compression on the MAX encoder.
The MAX encoder supports audio bitrates of 96K and 192K.
The MAX encoder supports audio sample rates of 32, 44.1, and 48K.
