3Gbps SDI Support & Features on FSI Monitors
 
3Gbps SDI is a powerful connectivity option for monitoring of advanced signal formats whose bandwidth is up to two times that of standard 1.5Gbps HD-SDI signals. FSI Monitors equipped with 3Gbps SDI inputs, such as the LM-2461W, can support both Level A and Level B 3Gbps SDI signals. The equipment is therefore said to conform to SMPTE 425M-AB. Via Level A 3Gbps SDI Flanders Scientific monitors can support the following advanced formats that are not supported by standard 1.5Gbps HD-SDI:

Level B is distinct from Level A in that it does not employ direct image format mapping. Simply put, this means that Level B 3Gbps SDI essentially supports two distinct 1.5Gbps (SMPTE 292M) signals combined (multiplexed) over a single 3Gbps SDI connection. This includes Dual Link (SMPTE 372M) signals that have been multiplexed together over a single 3Gbps SDI stream using Level B image format mapping (use Overlay Mode to monitor these signals). The Level B 3Gbps SDI capability on FSI monitors allows for the following unique monitoring options when the 3Gbps SDI signal is comprised of two distinct 1.5Gbps HD-SDI signals:

• Link A and Link B streams in the 3Gbps SDI Level B signal MUST be the same format. For example, you cannot combine a 1080i and 720p signal over Level B 3Gbps SDI. Link A and Link B must have the same frame rate and same resolution to be supported over Level B 3Gbps SDI.
• Link A and Link B must be genlocked. A high quality sync generator should be used for all signals that will be multiplexed over a single 3Gbps SDI stream.
