Blackwave Chorus™ Software

Download PDF Overview

Blackwave Chorus™ software is at the heart of every Blackwave System and represents the newest industry standard for enhanced video delivery performance. Blackwave Chorus enables delivery across multiple protocols to large audiences at the lowest cost per stream.

Blackwave’s technology, designed both for companies now entering the video distribution business as well as established companies, enables organizations to grow their business, to reduce management complexity, and to improve profitability.

Optimized for IP Video
Unlike traditional enterprise systems, Blackwave Chorus is optimized for IP Video:

• Algorithms leverage the unique attributes of streaming media to optimize bandwidth and capacity.
• Blackwave combines video delivery with disk provisioning and scheduling to accommodate large numbers of viewers.

Traditional content delivery systems combine storage capacity with performance capabilities: if you need additional bandwidth, you must create more storage. Blackwave has changed that paradigm, enabling customers to independently scale either streaming/download performance or storage capacity as market requirements and business needs evolve.

For companies that want to achieve high bandwidth and increased session counts, Blackwave Chorus ensures maximum utilization of hardware resources to:

• Avoid overprovisioning by delivering at a bandwidth equal to the bitrate of the video.
• Modulate download speed to ensure smooth video across large viewing audiences.
• Increased customer satisfaction.
• Reduced capital and operational costs.

Enterprise-Class Video Delivery
Blackwave offers robust, high-quality video delivery with huge audience capacity across multiple delivery protocols:

• Deliver 10's of Gbps streaming and up to several thousand sessions
• Regulated Progressive HTTP Download.
• WMS & Flash.
• Elimination of single Points of Failure.
• Self-healing content repairs media corruption and disk failures.

Simplified Multiprotocol Content Ingestion

Initially, resources are provisioned at ingest, then dynamically reprovisioned based on patterns of use during the content’s life cycle on the system. This introduction of real-world intelligence into the resource provisioning process eliminates one high operational cost of traditional storage systems, i.e. the tear-down and re-creation of volume and file systems in response to changes in resource requirements.

• Enables uploads of multiple terabytes per day.
• Eliminates impact of ingest on delivery performance.
• Supports HTTP, FTP, CIFS, and NFS protocols.

The Blackwave System optimizes resource allocation at the title level, and not the volume level, This eliminates the need to over provision storage to accommodate the performance objective of a small minority of titles in the content library. Therefore, improved performance utilization means significantly lower expenditures.

Multi-tiered, Distributed Access
A Blackwave System can access content on other Blackwave Systems and relay it to the viewer:

• Mid-tier Blackwave systems can access one or more origin system.
• Content is delivered while simultaneously cached.
• Future references to the mid-tier can deliver from cache, optimizing network utilization.
• Unused cached content is evicted to allow more resources to be dedicated to popular content.

Easy Management
Blackwave allows for simplified management and reporting across geographies:

• Offers a unified view of video delivery.
• Enables simple content provisioning without needing to manage volumes or filesystems.
• Allows for monitoring of system health with SNMP.
• Simple emailing home of System Health and System Events.
• Enables billing integration between Syslog / Weblog.
• Offers multi-tenant support.

Blackwave Systems readily integrate with all the existing systems in the IP Video value chain. The ease of scalability, simple integration, and minimal deployment complexity ensure low ownership expenditures, even as the need for a more complex IP Video infrastructure may increase over time.
