DELTACAST always offers more, at no charge!

DELTACAST products constantly evolve by the way of new releases of the VideoMaster SDK.

For those who do not have access to the VideoMaster SDK release notes, here is a summary of the features and working modes we recently added to our various product families.

This might trigger new ideas for your own application based on DELTACAST products.

 

 

DELTA-3G-elp-d 4c NOW SUPPORTS 4:2:2 YUV PLANAR BUFFER FORMATS 

Planar YUV is typically the preferred picture buffer format of video encoders and decoders.

In addition to 4:2:0 YUV planar formats already supported on a series of DELTACAST cards, we added support for different 8 and 10 bits 4:2:2 planar formats on the DELTA-3G-elp-d 4c.

 

 

 

 

FINE SDI OUTPUT CLOCK TUNING ON DELTA-3G-elp-d 8b  

In some applications, it is useful or even essential to be able to fine tune the frequency of emitted SDI signals. Typically, this is needed in live decoders and video processors when the SDI output needs to be slaved to some external reference.

Most DELTACAST cards hosting SDI output channels already allow tuning the output clock frequency.

We went one big step further on the DELTA-3G-elp-d 8b, implementing a new solution offering an unprecedented accuracy.

Actually, SDI output frequency can now be adjusted by steps smaller than four thousandths of ppm!

 

FRAMES TIMESTAMPING AS YOU WANT

So far, VideoMaster offered captured frames timestamping based on the host computer wall clock, the one which gives the time of the day.

While it was accurate enough for most use cases, some applications were disturbed by potential discontinuities occurring upon PC clock synchronization on a server or upon manual time of the day adjustments.

To cope with that, we added two new modes, available for all DELTACAST cards, where incoming frames are time stamped using :

• Either a monotonic clock without discontinuities, now still subject to frequency adjustments linked to NTP synchronization.
• Or a monotonic clock not subject to any NTP adjustment.

 

MULTICAST SUPPORT ON DELTA-ip-ST2022-6 CARDS

All DELTACAST ST2022-6 cards now support multicast reception and transmission by the way of the IGMP protocol.

 

 

 

 

 

macOS HIGH SIERRA AND THUNDERBOLT 3

When new operating systems versions are released, DELTACAST performs intensive qualification tests to ensure that compatibility and performances of all its products are still met. Sometimes, small adjustments must be made to fit the new operating system characteristics.

This is the case for macOS 10.13 High Sierra, which we now fully support.

We also took the opportunity to measure performances increase brought by Thunderbolt 3, and with a light adjustment made on our most demanding products – see the list below – we can now fully take advantage of the massive bandwidth delivered by this new interface.

Upgraded products are :

• DELTA-3G-elp-d 4c, 8b, 84 and 80
• DELTA-3G-elp-tico-d 4c
• DELTA-3G-elp-2key-d 22
• DELTA-3G-elp-2key-d 44
• DELTA-3G-elp-key-d 4K

 

HOT PLUG DETECT TRIGGERING ON DELTA-h4k2-elp

HDMI is a plug and play standard, allowing a sink devices to be connected to a source equipment while both are powered on. In this case, a negotiation based on EDID information allows the source and receiver devices applying the correct display settings.

VideoMaster now includes the ability to control the HPD (HotPlug Detect) and DDC (Display Data Channel) pins of the HDMI connector to simulate HDMI cable plug and unplug from the application, what is particularly convenient for certain types of applications, like video analyzers.

 

 

 These features are all available in the latest VideoMaster SDK release sitting on the DELTACAST website download center section.

Do not hesitate to contact DELTACAST for further information about these features, or if you want to share specific requirements that we could meet.
