OASYS IP and SDI at CABSAT 2024

/in ,

Our Development Team has devoted significant time and effort into developing new features for OASYS IP and SDI at CABSAT 2024 over the past few months to improve performance, save time for operators and expand our automation features.

Improved CPU Usage
CPU demands are greater with high bandwidth IP streaming and we’ve recently improvee CPU efficiency by 50% for better overall performance in systems with multiple CPU servers.

Loudness normalization
Loudness normalization has become a big regulatory concern in many markets. OASYS can now apply loudness normalisation on-the-fly, for both live contribution and file playout (supports EBU R128 and ATSC A/85 including Dolby Dial norm). This saves the cost of a dedicated separate loudness normalization unit.

Kill dates for assets
The new kill date facility in the OASYS media library allows uers to ensure that programs are not transmitted after their licensed window and that commercials do not air after the campaign expires.

Improved Graphics functions
To improve channel branding, new graphics functions include masking, scaling and stretch effects have been added to make it easier for the user. In addition all graphics changes can now be previewed live.

Improved support for soft segmentation (EDL)
Re-working assets to insert varied black markers for different ad patterns is frustrating and time-consuming. OASYS playout now allows users to use a simple cue sheet as an EDL against longform assets. The same asset can be played out on different channels or schedule slots with different ad-break patterns without the effort of re-working the asset. Modifications in OASYS to support this workflow also include changes to apply the cue sheet changes to the asset prior to the file integrity check and QC functions. Email notification has also been added for QC failures.

New Dolby D and Dolby E support
OASYS now supports pass-through and encode of Dolby D into IP outputs and decode and pass-through of Dolby E for SDI and IP outputs.

Audio Upmix
To improve the viewer’s listening experience further, OASYS can now also generate a 5:1 surround sound mix from a regular stereo soundtrack.

Improved SCTE-35 Triggers
OASYS can now embed multiple metadata items in each SCTE-35 packet – allowing separate targeting of downstream events (e.g. for different regions).

Automatic Aspect Ratio Control
OASYS playout can now dynamically set the aspect ratio based on AFD information in the ancillary data of an asset or sidecar XML, saving users the time needed to do this manually and avoiding the risk of getting it wrong.

View all incoming audio tracks in single UI in Maker
The user can now see all incoming audio tracks on a single page and no longer needs to navigate to multiple pages. Saves time and makes the operator more productive.

Multi-Channel Web Client
Live prepared preview is now available in Multi-Channel Web Client. Before, this was only available via the desktop application.

New Polistream Software Release v3.7.0.74

/in , ,

Polistream U8100 1RU Server

BroadStream is pleased to announce a new software release for Polistream. Since the acquisition of Screen in late 2018 one of our goals has been to double-down on product improvements on all Screen products and you will begin to see new releases on a regular basis. Our two software teams in the UK and Croatia have successfully merged and now work together as one team.

This new release for Polistream provides an initial release of support for DVB-TTML, which is DVB’s new specification for text-based subtitles. The new TTML delivery specification will provide a transitional path to a common TTML subtitle format for both broadcast and Internet-delivered services. This means subtitles used for broadcast can be re-used later for video-on-demand services over DASH/CMAF.

DVB-TTML is especially suited for high resolution content like 4K and higher resolution programming that will be produced in the future. It is also closely aligned with other TTML-based systems including the EBU-TT-D specification, which was adopted for both DVB-DASH and HbbTV. You can learn more about DVB-TTLM here.

Initial Release of support for EBU-TT Live input and output uses Websockets. EBU‑TT can be used in a broadcasting environment to carry subtitles that are created in real time (“live” or from a prepared file) from an authoring station to an encoder prior to distribution, via intermediate processing units. EBU-TT Live Part 3 is carried over Websocket allowing input and output as Client or Server. You can learn more about EBU-TT here.

This new Polistream release includes:

  • Support for text backgrounds (TTML tts:backgroundColor attribute)
  • We’ve also added an EBU-TT-D text background selector on the UI Options page. This can be set to OFF, ON, or AUTO which enables backgrounds to be “forced off or on”, or it can be controlled by the box attributes in the subtitle.
  • When backgrounds are “ON”, the background color is black by default at the start of each row and may be set to other colors by the “new background” control codes embedded in the subtitle text.

Customers with an active support contract can contact Support(at)BroadStream.com for access to this software upgrade.
