CONNECTING AND OPERATING THE 3GSDI TO HDMI 1.3 SCALER

SDI Input Format
When the Scaler sees a valid SD/HD/3G-SDI source as input, the format is displayed at the
bottom of the OSD and checked in the menu choices. “Auto detect” appears if no valid input
is found. In such cases, the Scaler can be set to use a specifi c format. To do so, set the link
confi guration fi rst (see below) to avoid mistakes such as confusing dual link resolution with
single link (as in 1080p). With SDI single link, the input source can be set to SDI input 1 or
SDI input 2. Therefore, exert caution when setting the input format.

SDI Input Link Confi guration
The Link Confi guration must be set to correctly recognize the type of input signal. Many SDI
dual-link signals can be interpreted as single link. Examples of valid SDI link confi guration
menu choices in the OSD are shown below in Figure 17. The SDI source MUST be
connected fi rst or the Scaler will not allow link confi guration. The selected link confi guration
appears marked in the list of choices (see Figure 17). Incompatible choices will cause the
Single Link mark to remain selected without an operation being performed.
Figure 17 - Link Confi guration
When processing a dual-line interface with two input signals at 1080i each, you must
select the Dual Link 1080p/576p/480p option, otherwise the incoming input signal will
be interpreted as a single-link 1080-line interlaced signal. The same applies to 576p and
480p, which are seen as 576i and 480i. Many other problems can occur from a bad link
confi guration. Every time the input link type changes, you should re-confi gure it in the OSD.
