Features & Benefits
Fast & Scalable
Fastest QC system in the market with up to 6x faster than real-time analysis speed for HD content and near real-time analysis for JPEG-2000 4K content. Faster QC results into lesser licenses for a given content volume with a direct impact on investment in the QC system. It also improves the workflow throughout with quicker access to QC results. You can also easily setup a verification cluster with multiple QC verification units for higher system throughout.
High Dynamic Range
Perform QC of your Dolby-Vision, HDR-10 and HDR-10+ content. You can perform a variety of metadata validation checks along with detailed reporting of HDR parameters. You can also cross-check the video properties between the HDR metadata and the video essence. The HDR toolset in Pulsar is the most comprehensive and can significantly aid in setting up & managing your HDR workflows efficiently.
Interoperable Master Format (IMF)
Pulsar has the most comprehensive support for IMF packages. Some of the key capabilities include:
- Support for Application# 2E and SMPTE TSP 2121
- Package validation
- Supplementary package support
- CPL and OPL based validation
- Sidecar composition map validation
- Photon integration
VOD and Adaptive Bitrate
With built-in support for adaptive bitrate formats as well as fragmented MP4, Pulsar allows users to automate the QC of Video-on-demand assets. Key capabilities include:
- Formats. MPEG-DASH, Apple HLS and Microsoft Smooth Streaming
- Encrypted packages support.
- Auto-assignment of different QC templates to different encoding profiles.
- Adaptive bitrate package specific checks to help validate the integrity of ABR packages.
Ensures that your content is compliant with country regulations as well as against your customer specifications.
- Photosensitive Epilepsy using Harding PSE engine & get a Harding certificate for every job.
- Compliance with Audio loudness against CALM act, EBU R128 and OP-59 recommendations.
- Compliance with legal luminance & chrominance range or RGB Gamuts.
- Compliance against presence of Emergency Alert System (EAS) messages in the content.
- Compliance against Netflix, iTunes, DPP, ARD-ZDF and many other organizations using our ready-to-use factory templates.
Many content application such as Advertisement content delivery, requires certain content segments to be present at head and tail of the content. These content segments may include color bars, black frames, freeze frames, slates, audio mute, tones and silence. You can setup your custom track layouts and validate the overall structure. This can be done in conjunction with the template checks.
