Decoder SDI (Option)
If DRP 393 is equipped with the SDI option the menu “SDI” appears in the decoder main menu. The
“Decoder SDI” menu appears when you click on “SDI”.
There are two selection options in the “SDI Mode” menu:
SD/HD OUTPUT
: The SDI output signal corresponds to the resolution of the decoded video signal i.e. if a
SD video signal is decoded a 270 MbpsSD-SDI signal is available at the SDI output. In that case the
analogue CVBS video output also carries the corresponding analogue video signal.
If a HD video signal is decoded a HD-SDI signal with a data rate of 1.485 Gbps is available at the SDI
output. In this case the analogue CVBS output is disabled.
SD ONLY OUTPUT
: The SDI signal is given out with a data rate of 270 Mbps. If a HD programme is
decoded a downscaling takes place on the basis of the SD resolution. The analogue CVBS video signal is
given out simultaneously.
If a SD-SDI signal is given out there is an option of transferring VBI information in the SDI. Information for
Teletext, data line 16, WSS, test lines and line 329 is directly transmitted digitally in the corresponding lines.
The individual VBI information can also be disabled. Disabling the VBI transmission via SD-SDI does not
have any influence on the insertion of VBI information in the analogue CVBS signal. The VBI information is
not available for a HD-SDI output.
SD- and HD-SDI signals are transmitted with embedded audio. 2 stereo-/dual-tone (4-channel) audio
signals can be transmitted in the SDI signal. The sampling rate for embedded audio signals is specified as
48 kHz by default. If a service is received with another audio sampling rate (e.g. 32 kHz, 44.1 kHz) and
transmitted via SDI the sampling rate is internally automatically converted to 48 kHz. Besides a digital audio
output conforming to AES/EBU is available. A stereo-/dual-tone signal can be transmitted via AES/EBU.
