The encoder is configured and operated from the web browser. This section explains how to
configure and operate the Codec as a video encoder.
The encoder is configured and operated from the web browser. This section explains how to
configure and operate the Codec as a video encoder.
2.1 Configuring the Encoder
2.1 Configuring the Encoder
2. Click on “Profile” under “Encoder” from the menu on the left. “The Encoder Profile”
interface should display in the main area to the right of the menu system, as shown in
Figure 1.
3. Enter the destination IP address and UDP port number, transport stream (TS) bitrate, and
modify the other audio and video parameters, such as Stream Type, Audio Bitrate (in Kbps),
Audio Sampling Rate (in samples/sec), Video Frame Rate, Video Encoding, Video Format,
Video Resolution, Video Aspect Ratio, and Video Input, to suit your needs. If you do not wish
to encode audio along with the video signal, select 0 for the Audio Bitrate. The choices for
video input are: Composite, S-Video, CATV (Cable TV RF signal), and OTA (Off the Air RF
signal). Enter a bit rate that is appropriate for your network and application.
The user interface will warn you if you try to enter a bit rate beyond the operating limits of the
codec. For more details on the range of MPEG encoding bit rates, please see Appendix C
(Section 13.3). For more information on the various video and audio parameters (Frame
Rate, Encoding, Format, Resolution, etc.) please see Appendix A (Section 13.1).
4. Press the “Save” button to save your changes. None of your changes will be saved nor have
any effect unless you first save them.
Note: The maximum audio input signal is -1 dBu (0.976 Volts peak, 0.690 mV rms). Above this
level, the audio signal will clip (flatten out). By default, an MPEG2+4 IP Codec configured as a
decoder outputs the analog audio signal with a total system gain of 1.83. (As explained in Section
3.2, you can adjust the decoder audio output signal level.)
2.2 Starting the Encoder
Enter http://IPAddress where IPAddress is the IP address of the encoder.
1. Select
the
Encoder
menu on the left side of the web page.
2. Select
the
Start
menu option underneath the Encoder menu.
Note: While encoding video from the TV Tuner interface (CATV or OTA), you can change the
channel at anytime by selecting “Set Chan” from the encoder menu, entering the desired new
channel, and clicking the “Change Channel” button.
Note for WiFi Operation: If your MPEG2+4 Codec includes the WiFi option and you plan to send
video over the Ethernet port, we recommend that you disable the WiFi adapter, as explained in
Section 9. Please also refer to Section 11, Known Problems.
