yes Case Study
yes DBS, Israel’s provider of TV broadcasts via satellite, processes large volumes of video content to serve over half a million customers. This company used manual processes to handle many video conversion points, subtitling, and output format requirements. Manual processes required expensive expertise and were time consuming.
The technical team at yes wanted to automate video conversion to the maximum, aiming at increased speed, productivity and quality. Additionally, the team wanted to integrate automation with its media asset management system from one of the leading vendors in the broadcast industry.
Using our flexible platform, we built for yes a series of automated workflows addressing their video conversion needs.
A few transport stream samples were prepared for testing on set-top boxes. After a few test iterations and profile fine-tuning, we reached a video that looks great, plays back smoothly and keeps the bandwidth to a minimum.
yes had to include 2 different languages with each VOD file, using subtitle files from an external subtitling studio. We set up the workflow that detects the language based on predefined naming conventions, converts data into DVB subtitles and syncs the subtitle time code to the video).
Other VOD formats intended for mobile or PC platforms, had subtitles burnt in the video, resulting in 2 separate video files for each language.
Integration with MAM system
The team at yes wanted that each video title will have a transcoding deadline date in its metadata, coming in from the MAM system. We designed the automated workflow so that it automatically assigns different priority levels based on the metadata, which can be configured by the user. Additionally, a component control lets users allocate specific encoders to specific profiles according to the available tasks. Together, these two methods ensure all videos are delivered on time.
Automatic decision making
Automation was optimized to reduce manual user intervention to a minimum. Some examples include:
- Decision rules for handling multi-channel audio, pass-through and
- encoding to industry standard surround sound formats.
- Decision rules to auto-detect re-wrapping scenarios and reduce transcoding time. For instance, incoming IMX/XDCAM files which are found to be fully compliant get skipped during the encoding phase and are simply re-multiplexed into yes’ broadcast server format.
- Detecting subtitle language in metadata files incoming from the MAM.
