Round the Clock, 90 Days, Keep Disasters at Bay:
DVStor2 –Transport Stream Recording & Playout

   
What happens when a feed fails? Content dictates a viewer’s experience; thus any disturbance to that experience places service providers into dire need of an effective disaster recovery strategy.
DVstor2
Pixelmetrix introduces DVStor2 – the ultimate solution offering a highly scalable, stable compliance recording with hot standby redundant switchover and a flexible, fail-safe architecture.

One vital feature of the DVStor2 as a disaster recovery system lies in the ability to detect loss of signal on input streams. As DVStor2 continually records and analyzes transport streams, it can trigger the play out of the recorded transport stream over either the IP or the optional ASI port upon detecting an input failure..

The DVStor2 can control an external ASI switch to change from the live feed to the recorded signal, such as pre-recorded time-shifted content. As transport streams are modified on the fly, neither the viewers nor the downstream equipment can discern between a live transmission and a recorded version.

DVStor2 eliminates the need for costly external storage by offering maximum compression. Video services can be transcoded in-place without modifying the transport stream structure. Efficient storage space is further achieved as DVStor2 notes the presence of null packets in the stream, removes them when recording and reinsert them on playback.

The call for added storage escalates in urgency as the number of channels soars in tandem with increased bandwidth. The DVStor2 is available in capacities ranging from 1TB to 48TB of storage space. With support for Direct Attached Storage (DAS), the storage capacity can even be boosted up to 120TB, which is one of the highest storage densities in the industry. This literally means storing media in excess of a year without the need for human intervention.

Complete metadata and EPG decode also allow easy troubleshooting. By providing a full recall of all content, captions and metadata, the DVStor2 can archive the entire transport stream in full resolution and exactly as broadcasted. It can either continuously record in a loop or record only segments with errors. Moreover, it can generate video thumbnails that allow operators to have a bird’s eye view of the transmission. So, even after a disruption, operators can access the recorded TS, point to a suspect video thumbnail and quickly locate the error.

In addition to the disaster recovery and troubleshooting features, DVStor2 is an ideal system for legally mandated compliance recording. For quality audit purposes, DVStor2 is deployed to archive TS round the clock for up to 90 days off a satellite transponder and time code burn-in on playout or export, which makes the DVStor2 a long-term test source for validating broadcast equipment.

Unsurprisingly, the DVStor2 also offers maximum protection of the archived content. Given a secure, fail-safe RAID-6 redundancy with hot-swappable spare hard disks and dual-redundant power supplies, the DVStor2 offers a redundant fail-over configuration using either one-to-one or N-to-one set-up that streamlines the entire content playback.

In essence, the DVStor2 is the perfect fit for content disaster recovery, transport stream recording and playback. Ensure maximum reliability. Let the DVStor2 dispel all your worries.
