Media origination is a mission-critical function for the delivery of advanced revenue-generating media services to consumers. With the Cisco Videoscape™ Distribution Suite Origin Server (VDS-OS), Cisco rethinks media origination by incorporating the critical media encapsulation functionality necessary to streamline deployment of HTTP Adaptive Bit Rate delivery. Cisco® VDS-OS is a cloud-based software platform that supports HTTP media origination and on-demand encapsulation (ODE) 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 HTTP Smooth Streaming (HSS), Apple HTTP Live Streaming (HLS), and Adobe® HTTP Dynamic Streaming (HDS) formats. The Cisco VDS-OS management and services framework provides rapid service creation and deployment on the operator's computing infrastructure in a simple, flexible, and scalable manner.
Features and Benefits
Cisco VDS-OS helps operators deliver services faster by providing core media origination capabilities, based on multiformat HTTP adaptive streaming and HTTP progressive download, all in a single commonly managed platform.
• Video on demand: Cisco VDS-OS is a VoD origin server for Apple, Microsoft, and Adobe HTTP streaming. It can replace or augment existing Microsoft IIS and Apache Origin Servers. Cisco 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 formats.
• Live linear: Cisco VDS-OS makes it easier to turn up live linear services by supporting multichannel origin services that can receive synchronized redundant feeds and support multiple publish points for individual live channels, allowing operators to create tailored service offerings.
• Time-shifted TV: Cisco VDS-OS supports a configurable digital video recorder (DVR) window, which can be contained in RAM or on external storage, depending on the operator's preference. Program "restart" services can use the DVR window to allow subscribers to view content anywhere within the window. Additionally, to support external recorders, Cisco VDS-OS can serve as a scalable, high-performance, on-demand encapsulation platform. In this case, it sources content from the recording system or archive, as needed to meet media requests for fully encapsulated HLS, HSS, or HDS content, and it applies appropriate digital rights management (DRM) encryption as the operator requires.
Resiliency and Load Balancing
Cisco VDS-OS provides a highly resilient operational environment. The Cisco 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 Cisco VDS-OS server. Cisco VDS-OS can also support alternative request-routing methods, depending on customer need.
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, also known as JITP) is enabled, Cisco VDS-OS sources content stored in indexed MPEG2 adaptive transport stream (ATS) format, such as can be provided by the Cisco AnyRes VOD transcoder or Cisco VDS-TV Recorder. When there is a request for a media fragment of a particular adaptive streaming format (such as Microsoft HSS, Adobe HDS, or Apple HLS), the Cisco VDS-OS will provide it by encapsulating the ATS source content in real time. This includes providing DRM encryption. As a result, the Cisco VDS-OS allows the operator to achieve significant cost savings on library storage by storing only the single ATS format, rather than all the end-device formats it is required to deliver.
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+ are supported). Cisco VOSM facilitates flexible and scalable device management, making it simple to add and remove servers within the Cisco VDS-OS cluster, and it also 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 user interface, or through Cisco 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, encapsulation and packaging settings, 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 Cisco 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. Cisco VOSM also provides reports covering critical service-specific and content-specific statistics, using raw data it receives from individual Cisco VDS-OS servers within the cluster.
