Video Surveillance Trends

Digital, networked surveillance systems can improve situational awareness at lower costs, but increasing amounts of information require more sophisticated management of bandwidth and storage.

A new breed of 'smart' encoders provide real-time analytics and deliver more image detail for events, areas or objects of interest. Recently, standards suitable for surveillance have emerged, such as H.264 SVC, that offer native multiple streams support to further reduce storage and bandwidth costs.

This increasing diversity pose a significant challenge to systems designers. Conventional DSPs or processors can't to keep up with increasing performance requirements, and fixed-function ASICs can't keep up either, due to the diverse feature demands.

SPI's Technology Benefits

SPI's Storm-1 solves the performance and flexibility problem by bridging the gap between ASIC efficiency and DSP programmability flexibility. Standards-based C development with embedded Linux allows manufacturers to adopt a scalable software-driven model and enjoy a strategic advantages over ASIC-centric approaches.

The performance headroom for Storm-1 allows manufacturers to allocate processing to meet diverse requirements, such as minimizing cost per channel in an embedded DVR or build a state-of-the-art analytics appliance.

Examples of features :

• Support any codec standard, any resolution ; Soft codecs allows for tuning for video surveillance and support analytics integration. H.264, MPEG-4 and MJPEG encoders and decoders are available from SPI today.
  
  
• Video processing library ; dynamic flattening, rain/fog processing, image stabilization, motion adaptive deinterlacing, and advanced noise reduction.
  
  
• Search library; Real-time indexing and forensic event search. Face detection and recognition.
  
  
• Intelligent video analytics library; from basic tamper detection and people counting to behavioral analysis.
  
  
• Display processing library; OSD, alphablending and scaling, supporting SD, HD and UXGA outputs.
  
  
• Image sensor processing library ; Up to 12 Megapixels, including digital PTZ with multiple windows.
  
  
• Network stack: RTP/RTSP streaming, iSCSI storage stream, multitasking application plug-in framework, webserver, etc.

Up to 16 channels of video can be processed in a single Storm-1 G220, making it suitable for DVRs, Hybrid NVRs and Video Encoders, offering a low total cost per channel, competitive differentiation, and guaranteed interoperability.

The entry-level Storm-1 G30 is ideal for IP Cameras with smart video compression and analytics. All in a single-chip solution running standard Linux.

SPI's tools, libraries and framework help customers to quickly get to market.
