The Espial MediaBase Internet Server (MBi) provides the features to ingest ABR media assets, capture live TV in ABR formats and provide http streaming. It enables live TV, Time-Shift TV services and VOD services. It intelligently distributes content to other MBi servers.

Features & Benefits

Unified TV Everywhere Platform

Espial MediaBase supports both HTTP and RTSP streaming from a single platform to dramatically increase utilization of computing and storage resources. As well, it offers a single content delivery network for MPEG video assets and adaptive bit rate (ABR) video assets. With these capabilities, Espial MediaBase can reduce CAPEX and OPEX expenditures by 50% and 65% respectively compared to competing on-demand video systems.

Seamless Expansion

Espial MediaBase is designed to support rapid growth: starting from a simple centralized deployment, operators can quickly and easily expand to a multi-tier storage, streaming and server clustering architecture. This allows them to meet extraordinary growth in demand. One Espial customer has realized a six-fold increase in content storage and a four-fold increase in streaming capacities over 5 years. Over this period, they expanded from a single central site to multiple regional sites while expanding at a 32% annual growth rate.

Low TCO

Espial MediaBase implements many cost saving capabilities. It features patented technology to monitor storage, streaming, and servers to optimize network and hardware utilization. It’s high performance networking (HPN) and high performance I/O (HPIO and HPIO-A) achieve the maximum utilization of computing resources. A flexible pay-as-you-grow software licensing model allows customers to optimize.


Intelligent CDN

Espial MediaBase offers a built-in CDN capability and failover mechanisms with both unicast and reliable multicast content distribution to edge servers. With the Espial MediaBase Manager, content distribution from central servers to edge servers can be automated based either on dynamic changes in demand or configurable policy-based settings.

CDN Push for HTTP Objects

Espial MediaBase provides a CDN push feature for both private and 3rd party CDNs. For private CDNs using Espial MediaBase, it provides both MPEG and HTTP content management and distribution on a single platform. For 3rd party CDNs, it ingests, manages and pushes HTTP content using Espial MediaBase Manager tools.

Guaranteed Quality of Service

High Availability Design

Espial MediaBase runs on carrier-class COTS with fully redundant components and offers both AC & DC power options. It includes software RAID for an extra level of reliability. Built-in failover mechanisms support high availability within and across clusters.

Open APIs and Integrated 3rd Party Solutions

Espial MediaBase supports standards-based protocols such as Interactive Services Architecture (ISA). It also offers extensive Java and SOAP/XML APIs and has been integrated with over 15 middleware systems as well as a wide range of encoders, encryption systems and set-top-boxes worldwide.

MediaBase Manager

Content Distribution Management

Espial MediaBase Manager supports both point-to-point and point-to-multipoint multicast asset transfer. Administrators can define rules and policy and manages content distribution.
The transfer rules can be based on asset characteristics such as language, popularity and other criteria. For popularity-based transfers, Espial MediaBase can automatically push popular long-tail assets to one or more edge sites at run-time based on local demand. This feature enables service providers to respond promptly to unexpected high demands for certain assets, reduce backbone network bandwidth and reduce the storage requirements at the edge servers. This also reduces OPEX on manual operations to monitor, identify and transfer newly popular content to edge servers.

Configuration Management

In addition to server configuration, system administrators can control and assign physical system resources for efficient resource management. Content administrators can configure encoder parameters for live stream captures, Time-Shift TV (TSTV) services, NVOD services and also content sources (aka Content Stores) for content ingestion.


Reporting

Historical, aggregated and real-time reports can be generated to identify the asset inventory, current play out requests, failure information on asset ingest, asset play out, alarms triggered by reaching resource threshold and SNMP traps. All reports are available as time-based graphs for easy trend identification. Aggregated data can be kept for a defined length and after which system will start purging to make space for new data.

Monitoring

Administrators can easily track status of Espial MediaBase services including server-level applications and resource management, and also asset transfer and delivery services. Administrators can define alarm thresholds for managing SNMP traps for resource management.

Continuous Innovation

Harnessing the power of Moore’s law, COTS servers are continuously expanding their capabilities to drive dramatic improvements in performance for streaming, captures and networking. The illustrative charts to the right show the gains in streaming and storage capacity over several generations of COTS servers. In fact, today, many service providers can meet their streaming and storage requirements with a single server (non-redundant) per site.

Manageability

COTS servers off powerful remote server management capabilities that are always available, even if you aren’t physically at the server. Just log in and you can gain precise remote control of your server from anywhere in the world. As well, it also enables simplified server setup, power and thermal optimization, embedded health monitoring and remote restart.
