Harmonic powers OTT multiscreen service for Turkish DTH provider D-Smart
Fully integrated with CMS, DRM and CDN technologies, the Harmonic solution supports live, VOD and catch-up TV services.
D-Smart, a leading Turkish DTH provider owned by Doğan TV Holding, has selected an end-to-end video preparation solution from Harmonic to power its new OTT multiscreen service offering. D-Smart chose Harmonic's ProMedia adaptive bit rate (ABR), WFS file-based workflow, and MediaGrid shared storage systems. The integrated solution provides the scalability to deliver high-quality live, VOD, and catch-up TV services to any subscriber device, including TVs, PCs, set-top boxes (STBs), smartphones, and tablets.
The Harmonic multiscreen solution at D-Smart is part of an end-to-end workflow that includes full integration with content management system (CMS) and middleware technologies from Pixsel, digital rights management (DRM) technology from Discretix, and OTT content delivery network (CDN) services from Broadpeak.
The adaptive streaming services for D-Smart's new service offering are orchestrated by Harmonic's ProMedia Live real-time transcoders, which efficiently convert MPEG-2 and MPEG-4 AVC H.264 content to multiple high-quality ABR streams optimized for OTT delivery and multiscreen devices. By splitting encoding across multiple machines, ProMedia Live improves the processing workflow required for delivering streaming video. The platform also handles a variety of metadata information — such as language, captions, ad signaling/insertion — on input and output, further streamlining operations. ProMedia Live is integrated with Harmonic's ProMedia Package to enable sophisticated transcoding, encapsulation, metadata management and encryption from a single platform.
D-Smart's VOD services are powered by Harmonic's ProMedia Carbon and ProMedia Xpress file-based transcoders. ProMedia Carbon provides a range of critical operations, including SD/HD conversion, PAL/NTSC conversion, logo insertion, color space conversion, color correction and closed-captions extraction. Employing Harmonic's MicroGrid parallel-processing software technology, ProMedia Xpress enables faster-than-real-time transcoding and packaging of broadcast-quality SD and HD video for multiscreen VOD applications. ProMedia Carbon and Xpress are controlled by Harmonic's file-based WFS, which provides automated processing of high-volume transcoding tasks, failover support, job distribution management, job prioritization, load balancing, FTP transfer, status monitoring, and job notification.
Harmonic's shared storage optimizes the delivery of D-Smart's OTT multiscreen VOD and catch-up TV services, leveraging a range of industry-standard protocols, including Apple HLS, Adobe HDS and Microsoft Smooth Streaming. Tight integration between Origin and MediaGrid enable D-Smart to independently scale storage capacity, bandwidth and streaming capability.
