Overview

With file-based workflows increasingly moving to the cloud, it is only natural to have your file-based QC process within the cloud as well, taking advantage of the scalability and efficient resource planning inherent in the native cloud applications.

Quasar™ is the first native Cloud file QC service and helps you perform file-based QC on your cloud assets with ease. Encompassing all the latest features of Pulsar; industry’s most efficient automated content verification solution used by many large media corporations worldwide and built natively for the cloud architecture, Quasar™ promises the fastest rate of QC in the cloud.

Features & Benefits

Dynamic scaling

Quasar™ is an elastic system that can be auto scaled to any size without needing users’ intervention allowing hundreds of files being processed simultaneously. Performing QC on large content library or a content burst can be very time-consuming. With Quasar™, you never have to worry about varying content volumes. Just post them to Quasar™ for processing and it will be processed quickly. The QC jobs that would take months to process can be processed in just a few days.

Security & Latency

One of biggest worry for content processing on Cloud is the content security. Along with it, the content latency is also an important consideration. Following capabilities are available in Quasar to address these:

  • IAM roles support
  • Pre-authenticated URL
  • Temporary security credentials
  • No storage of user’s credentials anywhere in the Quasar system
  • No access to user’s content and the processing VMs to even our support teams
  • Auto provisioning of virtual machine in the content region. This has the following benefits
    1. No inter-region latency allowing faster content processing
    2. No egress charges
    3. Compliance with local laws that may prohibit the content movement outside the country/region
Service reliability

Quasar is a highly reliable service that has implemented a large number of service recommendations in terms of service reliability and security.

  • Advanced monitoring for early detection of any potential problems in the service performance
  • Detailed system logging allowing us to trace back any rare issues
  • Failover mechanisms allowing the workflow continuity in case of infrastructure failures
SaaS

Quasar service is available as fully managed SaaS service as well as a Private edition that users can deploy in their own virtual private cloud (VPC).
Following are the key benefits of using SaaS service:

  • Users don’t need to engage any of their staff for system mgmt. This alone can save significant time & cost for users, while focusing on their core business.
  • Users can immediately start using the Quasar system – either manually or via REST API.
  • Committed SLAs for service upkeep.
VOD QC

In addition to support for broadcast formats, Quasar supports VOD formats such as adaptive bitrate formats and fragmented MP4. 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
Harding PSE

We have integrated Harding FPA engine within Quasar. This allows users to perform Photosensitive Epilepsy validation using the industry defacto standard Harding PSE. Users will also receive a valid Harding certificate for every file processed via Quasar.

Quasar did save me considerable time this week in some last minute QC of live streamed content and found 3 issues that needed to be addressed. The speed and flexibility of Quasar processing was essential as the QC ran in a small window before going live.
