Its architecture allows for scaling service to include millions of subscribers. Recording, storage, and playback can scale independently, allowing service providers to optimize their investment based on channels served and usage data on recording and playback requests. VMR is a segment-based digital media recorder that records live packaged feed from Rekorder 1.2 - Rekorder - Rekorder 01 packagers compiled in Common Intermediate Format CIF media segments.

For recording, VMR consumes media data as segments from an upstream linear packager and parses the manifest files. When a segment corresponding to a Carol Of The Bells - Various - The Best Of Christmas request arrives, VMR captures the segment and pushes it to storage. For playback, a request to play back a recorded segment is triggered by a just-in-time JITP packager.

Compared with event-based offerings, VMR segment-based recording offers much greater storage efficiency. In addition, the stateless, segment-based architecture of VMR promotes resiliency against errors due to packet Rekorder 1.2 - Rekorder - Rekorder 01. Segment-based recording provides much greater efficiency than event-based recording methods. VMR stores all recorded content in segments that represent two seconds of playing time.

Before archiving recorded content, VMR analyzes each recorded segment to see if its content is unique or is shared in common with other recordings. VMR then removes all redundant content before moving the content from active storage to archive storage. This process, called deduplication, greatly reduces the overall storage space needed to support the same amount of recording time. Because of its segment-based approach, VMR allows recordings to be played either after they are completed or Midnight Thud - Various - MERZfunder (File) still in progress.

In-progress playout can begin shortly after the recording starts. VMR supports multiple simultaneous cDVR workflows, and as a result, can record multiple channels at once as well as multiple recordings of the same channel. VMR Rekorder 1.2 - Rekorder - Rekorder 01 external software components for linear packaging, just-in-time packaging, and storage, and these can be either Cisco or third-party products.

The VMR recorder core is deployed as a set of microservices deployed in Docker containers and using Kubernetes cluster-management software. This approach not only provides all of the benefits that container technology has to offer, but also provides a wide selection of deployment platforms including VMware, AWS, Rackspace, bare metal, and others.

Storage requirements are determined by the throughput needed to sustain peak recording requests. VMR enables operators to implement storage policy at the channel level to ensure that storage requirements honor the rights negotiated with different content providers and also comply with local legal requirements.

Different storage policies can be achieved by a combination of content deduplication settings and copy types. Content Deduplication—This scheme is configured on a per channel Spirit Of Radio - Solomon Grundy - Spirit Of Radio as dedupe or no-dedupe.

DeDupe—If a channel is configured as dedupe, all copies of the same content stored in active storage are deleted Rekorder 1.2 - Rekorder - Rekorder 01 only a single copy is stored in archive storage after a configurable archival time period. No DeDupe—If a channel is configured as no-dedupe, the metadata of all copies of the same content will be moved from in-memory database tables to on-disk database tables to conserve memory usage after a configurable archival time period.

Copy Types—Depending on legality, customers may select a copy type for each recording, either common or unique. Unique—If unique is selected, the storage system stores one copy for each subscriber in active storage. Common—If common is selected, the storage system stores one copy for all subscribers in active storage.

VMR consists of multiple microservices that work in concert to provide the digital recorder function. However, VMR also requires support from the external components as listed in the table.

The recommended configuration for a VMR deployment is a minimum of five VMR blades, with the remaining three blades allocated to all other components. Skip to content Skip to footer. Cisco Virtual Media Recorder 1. Book Contents Book Contents. Find Matches in This Book.
