high performance H.264 video compression solutions

Wavestore are experts in Linux based video recording solutions and have developed its proprietary high
performance video compression technologies.

The decision to integrate a commercial video compression technology was made when the flexibility and extreme processing performance of the Stretch products was demonstrated.  
The Stretch VRC6000 Series DVR cards use the compression capabilities and embedded analytics of the Stretch
Intelligent Encoder to reduce storage requirements and to maintain constant image quality at minimum bit rate. The Stretch VCC6000 Series capture cards can capture up to 16 channels of high quality video at full resolution and frame rate.
In addition, the Stretch technology supports the technology road map that Wavestore has defined which includes scalable video CODEC, HD video processing, and video analytics.

 

The VRC6000 Series of PCIe DVR Add-in Cards

                                                     

VRC6000 Series cards range from CIF resolution to high definition.
All cards use the Stretch Intelligent Encoder to perform full frame video compression using the H.264 Scalable Video CODEC (SVC), H.264 Advanced Video CODEC (AVC), MPEG-4, or M-JPEG.
Embedded analytics are used to optimize the CODEC setting to the dynamics of the captured video, ensuring the lowest possible bit rate. Video pre-processing ensures maximum image quality by
applying motion dependent de-interlacing and adaptive noise
reduction filtering.

See the Whole Picture

• CIF, D1, and high definition capture and compression in real time
• True H.264 encoding compatible with industry-standard players
• Constant quality encoding, video pre-processing, and embedded analytics
• Embedded analytics within the Stretch Intelligent
• Encoder can be targeted within user-defined regions of interest to trigger alarms when motion is detected
• The same alarms can be used to dynamically optimize the
  encoder to reduce the bit rate of the encoded scene.

The VRC6000 Series delivers everything you need to bring a high performance DVR card to market. VRC6000 Series add-in cards are completely software programmable, making them field upgradable and future-proof.
The VRC6000 Series firmware has a rich API, making it fast and easy to reuse existing DVR applications. An available software load contains all the firmware, drivers, and CODECs required to implement a high performance DVR right out of the box.

Alarm and Trigger Card VRC6008ALM

All members of the VRC6000 and VCC6000 Series are compatible with Stretch’s 8-input alarm and trigger cards.
These cards provide optically isolated inputs and relay outputs for receiving or generating stimuli in a surveillance system.

Video and Image Processing

When integrated with Wavestore the Stretch DVR cards provide extensive video pre- and post-processing

capabilities, including:

• Image enhancement and noise reduction
• Motion dependent de-interlacing
• Colour space conversion
• Multiple video stream placement
• User-defined tiling schemes

Stretch H.264 Scalable Video CODEC (SVC)

(This is planned to be released in version 4.14)
SVC streams can be scaled in real time to meet the bandwidth, storage, or decode requirements of the surveillance system.
By simply parsing the encoded stream, frame rate and resolution can be controlled without the need to decode,
re-sample, and re-encode the stream.
The Stretch SVC Extractor application can be used to extract backward compatible H.264 AVC streams for decode by legacy devices.
H.264 SVC is fully compatible with all cards in the VRC6000 Series.
When used in conjunction with VRC6000HD Series cards, it is the perfect complement to the cards’ high definition capabilities, delivering crisp HD video that can be managed over time to cost-effectively retain a long term video archive.
