Programming MHD-201 Modules
Aspect: Enables the image format to be selected, 16:9 or 4:3.
odec: Enables the encoding standard of the digitized audio and video signal to be selected from the options:
MPEG2 and MPEG4 (if the input signal is SD, the default will encoding will be MPEG2, if the signal is HD, encoding is
H.264 (1080p resolution only supports MPEG4).
Bitrate Video: (4-10 Mbits / s): The device can be configured for an input data encoding rate from 4 to 10 Mbits/s.
When selecting the encoding bitrate, the COFDM output bitrate must be taken into account, this should be sufficient to
support the encoding bitrate, in the opposite case the overflow alarm appears.
Bitrate Audio: The device can be configured for an input data encoding rate of 96; 128; 160; 192; 224; 256; 320
and 384 Kbits/s.
Low latency: Reduces encoding time for applications where response time is important (e.g. cameras). Selecting
the low-latency mode, has on the other hand decreased coding efficiency and image quality with a lot of movement.
Output: The MHD-201 modulator has two output types CODFM and IP. Using
the SPI-300 control only the first option can be configured, to select the IP mode
output use the web interface (see manual www.ikusi.tv).
