The new Rhozet WFS supports Harmonic’s Rhozet Quality Control System (QCS) to incorporate file-based quality testing and automated compliance as part of the transcoding process. WFS and QCS will be showcased at Harmonic’s booth #SU7213 during NAB 2010 in Las Vegas. WFS manages large-scale networks of Carbon Coder(tm) transcoder nodes in a distributed “farm” configuration. The distributed nature of WFS allows for automated processing of high-volume transcoding tasks, failover support, job distribution, job prioritization, dynamic load balancing, file transfer, status monitoring, and job notification. For even greater flexibility, WFS users can create comprehensive workflows that incorporate a variety of processing tasks and conditional behaviors tailored to meet their specific requirements. Additionally, with its extensive APIs and software developer kit (SDK), WFS can manage the complete video asset transformation process by integrating third-party applications and other Harmonic video processing solutions.
For advanced quality control capabilities, Rhozet QCS can be seamlessly added into the WFS and Carbon Coder transcoding architecture to significantly reduce the amount of manual intervention required to guarantee high quality output. Operators can use groundbreaking quality control features, configured to their specific needs, with an interactive tool for visual verification of output. The system analyzes all assets during the transcoding workflow to help identify possibly problematic files before, during and after the transcode process. QCS can be set to check a wide variety of video and audio characteristics, including black detection, silence detection, audio levels, letterboxing, blockiness, bit-rate, duration and transport stream compliance.
