Media origination is a mission-critical function for the delivery of advanced revenue-generating media services to consumers. Cisco Videoscape™ Distribution Suite Origin Server (VDS-OS) is a cloud-based software platform that supports HTTP media origination as a service. Cisco® VDS-OS provides a unified media ingest, preparation, optimization, and delivery framework for live, video on demand (VoD), and time-shifted TV (TSTV) use cases. Cisco VDS-OS supports multiformat HTTP adaptive streaming media origination for Microsoft Smooth Streaming, Apple HTTP Live Streaming (HLS), and Adobe® HTTP Dynamic Streaming (HDS) formats. The VDS-OS management and services framework provides rapid service creation and deployment on the operator's computing infrastructure in a simple, robust, flexible, and scalable manner.
Features and Benefits
Cisco VDS-OS enhances operator service velocity by providing, in a single commonly managed platform, the core media origination capabilities for services based on multiformat HTTP adaptive streaming and HTTP progressive download.
• Video on demand: Cisco VDS-OS is a VoD origin server for Apple, Microsoft, and Adobe HTTP streaming. VDS-OS can replace or augment existing Microsoft IIS and Apache Origin Servers. VDS-OS reduces the amount of storage required when the operator needs to offer multiple HTTP adaptive streaming formats by performing on-demand encapsulation of common adaptive format content into Apple HLS, Microsoft HSS, and Adobe HDS.
• Live linear: Cisco VDS-OS makes turning up live linear services easy by supporting multichannel origin services that can receive synchronized redundant feeds and support multiple publish points for individual live channels, allowing the operator to create tailored service offerings.
• Time-shifted TV: To support new revenue-generating services based on live-to-VoD recording, Cisco provides a license option to enable the Cisco Videoscape Distribution Suite Video Recorder (VDS-VR) within the VDS-OS cluster, supporting TSTV and cloud-DVR applications. Cisco VDS-VR records content in native HTTP adaptive streaming format for Apple, Microsoft, and Adobe, or optimally recording in a common adaptive format asset and performing on-demand encapsulation to achieve significant storage savings. VDS-VR provides interfaces for recording control and publishing of recorded content, integrating with Cisco's Videoscape Conductor Recorder Manager and Cisco Videoscape Media Suite products for those functions.
Resiliency and Load Balancing
Cisco VDS-OS provides a highly resilient operational environment. The VDS-OS Service Router employs proven Cisco service routing technology for optimized, load-balanced server selection. HTTP media requests received by Cisco VDS-OS from the content delivery network are directed by the service router to an appropriate server within the cluster based on the system load, origin service mappings, server health, and requestor's IP subnet. Server failures, storage access failures, network access failures, and live source failures can be withstood because the service router directs requests to another fully functional VDS-OS server.
HTTP Adaptive Streaming Optimization with Media Encapsulation on Demand
Cisco VDS-OS can perform media encapsulation on demand in a "just in time" fashion. When on-demand encapsulation (ODE) is enabled, VDS-OS sources content stored in indexed MPEG2 adaptive transport stream (ATS) format, such as can be provided by the Cisco Transcode Manager or Cisco Media Encapsulator. Upon request for a media fragment of a particular adaptive streaming format (Microsoft HSS or Apple HLS) Cisco VDS-OS will provide it by encapsulating the ATS source content in real time, including providing digital rights management (DRM) encryption. In so doing, VDS-OS allows the operator to achieve significant cost savings on library storage by only storing the single ATS format, rather than all the end-device formats it is required to deliver.
Cisco VDS-OS also allows the operator to deploy ODE-enabled VDS-OS servers in a distributed fashion close to the content delivery network (CDN) edge, thereby achieving significant bandwidth and cache storage efficiencies within the CDN core. The ODE-enabled Cisco VDS-OS servers at the edge work together with VDS-OS servers in the operator's data center to achieve these advantages.
Unified Provisioning and Management
Cisco VDS-OS provides the tools for a video operator to provision, manage, and monitor HTTP media origination services that power critical revenue-generating consumer services. The Cisco VDS Origin System Manager (VOSM) provides an easy-to-use browser-based user interface, web services APIs for back-office integration, and secure user and group role-based access (HTTPS, RADIUS, and TACACS+ supported). Cisco VOSM facilitates flexible and scalable device management, making it simple to add and remove servers within the VDS-OS cluster, and provides centralized device configuration and software upgrade capabilities.
Cisco VDS-OS introduces media origin services as a powerful, simplifying operational construct. The administrator provisions and manages origin services through the browser-based UI or through VDS-OS APIs, to provide critical media origination functions. Media origination operational parameters such as content sources, storage locations, publishing URLs, HTTP adaptive streaming formats, service rules, and quality of service (QoS) settings, are administered within the origin service. Origin services are overlaid on Cisco VDS-OS servers within the VDS-OS cluster, allowing easy and rapid scaling. As service needs change, origin services can simply be applied or unapplied to servers within the VDS-OS cluster as required.
Additionally, Cisco VOSM monitors devices and services, providing a graphical alarm console and corresponding Simple Network Management Protocol (SNMP) traps to northbound Network Management System (NMS) systems. VOSM also provides reports covering critical service-specific and content-specific statistics using raw data it receives from individual VDS-OS servers within the cluster.
