Imagine Communications has added a significant new element to its vision for anywhere, anytime television on any device. At IBC, the company is showing SelenioNext Just-In-Time Transcoding (JITT), an all software based on-the-fly transcoding system that almost instantly converts any video content for viewing on any device.
Imagine’s SelenioNext JITT significantly reduces the footprint of storage-intensive applications, which is why the technology is packaged with the company’s cloud DVR (cDVR). Imagine said it offers substantial savings in storage costs, while opening new monetization opportunities for video content owners and distributors.
Imagine’s CloudXtream DVR manages requests and changes from end users, and implements those requests and resulting distribution of content across the various network components and features. Powering cloud DVR and related services, and integrating with middleware to schedule and play back recorded content, the recording manager enables subscribers to use a wide variety of multiscreen devices to manage their recording activities and preferences.
Based on Imagine’s SelenioNext transcoder, SelenioNext JITT works with the cloud DVR to allow the service provider to store content in a single, high-quality bit rate format. Additional bit rates required for multiscreen deployments are transcoded only when a video asset is requested for playback. Imagine claims that the on-the-fly attributes of SelenioNext JITT can reduce storage requirements up to 80 percent.
Integrating multiple functions into a single-server platform, SelenioNext JITT provides dense, scalable and operationally efficient transcoding capabilities to meet demand for access to cDVR, IPTV and live programming from mobile and other connected screens.
Ron Gutman, Imagine’s senior vp of technology, said SelenioNext JITT can handle as many of 50 different versions of formats and can change over time. “Every person has its own virtual locker in the cloud and they can store all the content that they acquire for the cloud DVR,” he said. “That’s a lot of storage and by far the largest infrastructure cost for the cloud DVD process. This technology allows users to reduce that storage significantly.
“When you look at the cloud DVR where every person has his own one terabyte or 500 gigabytes of storage, if you need to store all the different formats it doesn’t leave a lot of room for linear hours of content. With this technology, only one high-quality version of the content is stored. When you watch it, we very quickly create the right format for the screen you are watching on.”
SelenioNext JITT also integrates with Imagine’s’ CloudXtream Dynamic Ad Insertion products. These enable service providers to experience cost savings in storage while also generating incremental revenue through ad placements.
Imagine said the technology also breathes new life into large VOD libraries, enabling content to be transcoded for ABR multiscreen delivery as needed. Combined with Imagine’s Telurio Packager, it allows service providers to stream their libraries in any required format. These include HLS, Smooth Streaming, HDS, DASH-TS and DASH-BMFF. This is accomplished with high capacity and density, as well as low power consumption.
“Video libraries and solutions require massive amounts of storage,” said Gutman. “A single copy of an HD feature-length film alone can easily consume up to six gigabytes of disk space. When coupled with Imagine’s dynamic storage management system, the new technology empowers service providers to simultaneously optimize storage resources and smoothly navigate the changing landscape of digital rights management.”
SelenioNext JITT provides density up to 80 HD ABR or 160 SD ABR channels per 2U server; maximum system redundancy with physical hardware, N+1 video processing, input source and output network interface; active balancing with an onboard resource manager that load balances video streams across all video processors in the system, providing an integrated fail-safe mechanism with no disruption to other live services.
The technology also provides advanced de-interlacing and compression techniques, which optimise video quality and compression efficiency at any bit rate and any resolution, and high power efficiency, using less than two watts per HD profile and less than one watt per SD profile.
