Operation/Reference Guide
The following options are available in the encoding section:
Perform these steps to configure the VBrick WMV multicast stream:
1. Select Configure Encoder from the Encoder menu. The Live Service page opens (FIG. 71).
2. Use the Video Input options menu to indicate whether you are connecting to the S-video, component, or
composite port on the encoder.
3. Use the Video Standard options menu to indicate which video standard the 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 Audio Input options menu to indicate whether you are connecting to the 3.5 mm jack or the Mic
DIN.
6. Use the Encoder Profile options menu to indicate which profile the encoder is using.
7. Use the Video Resolution options menu to indicate the video resolution of the multicast stream.
8. Use the Video Bitrate options menu to indicate the video bitrate of the multicast stream.
9. Use the Video Mode options menu to indicate the video mode of the multicast stream. It is recommended
that you select CBR.
10. Use the Audio Bitrate options menu to indicate the audio bitrate of the multicast stream.
11. Use the Audio Sample Rate options menu to indicate the audio sample rate of the multicast stream.
12. Click Apply. Clicking Apply saves your configuration.
13. Click the Enable check box to begin the multicast stream.
Encoding Settings Options
Enable Click to enable WMV streaming through the encoder.
Note: You will receive an error if you disable a Live channel while it is being
accessed by another service.
Multicast
Address This is the multicast address that will be used. This option is pre-configured
and cannot be changed.
Port This is the multicast port number that will be used. This option is
pre-configured and cannot be changed.
TTL This is the multicast TTL that will be used. You can enter a value in the space
provided. This option is pre-configured and cannot be changed.
Inputs
Video Input The encoder supports either S-Video, Component, or Composite video inputs.
Video Standard The encoder supports NTSC (USA and Japan) and PAL (rest of the world,
excluding France) video standards.
Aspect Ratio The encoder is supports a 4:3 and 16:9 aspect ratio.
Audio Input Select the audio input you want to use from the options menu.
Encoding
Encoder Profile Select the encoder profile you want to use.
Video CODEC Vision

supports only WMV video compression on the WMV encoder.
Video Resolution The encoder supports D1 (720 x 576 PAL / 640 x 480 NTSC) and SIF (360 x
288 PAL / 320 x 240 NTSC) resolutions.
Video Bitrate The encoder supports a range of selected video bitrates from 500 Kbits to 4
Mbits. The recommended encoding bitrate is 4 Mbits.
Video Mode The 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.
Audio Bitrate The encoder supports audio bitrates of 12K through 192K.
Audio Sample Rate The encoder supports audio sample rates of 32, 44.1, and 48K.
Channels The type of audio channel used by the encoder.
