Bosch Case Study“The reason we need such highperformance is that we need toanticipate that an operator may addHD cameras to the device. The goal isto support four HD cameras withoutlosing framesand provide fluid video in allideo windows.”Konrad SimonProduct ManagerBosch Security SystemsAdvantages ofIntel ® Architecture• Decoding Performance todisplay high definition andstandard definition video fromcameras and encoders usingH.264 or MPEG-4 encoding atup to 30 images per second• Compatibility with WindowsbasedBosch decoder softwaresuite and ease of futuresoftware updates• Fast development frominception to finished productin 7 months• Intel ® processor road mapenables Bosch to target evenhigher levels of decoderperformanceThe decoder is part of a total management system created by Bosch thatenables remote control without direct user interaction. “Video managementsoftware running on the decoder ensures that each video stream gets sufficientperformance to maintain smooth as possible video performance on eachwindow of the display,” says Simon.“A prerequisite was that we wanted to use our existing PC-based video softwarefor decoding and rendering, in addition to software that provides connectioncontrol and distribution of video over selected screen layouts.”The two software components include Bosch VideoSDK 5* software, capable ofhandling simultaneous rendering and decoding of up to 256 video streams, inaddition to Bosch Monitor Wall* software to provide connection control anddistribution of video over selected screen layouts.”“The reason we need such high performance is that we need to anticipate thatan operator may add HD cameras to the device. The goal is to support four HDcameras without losing frames and provide fluid video in all video windows,“says Simon.Video Decoding Workload Analysis ToolBosch collaborated on the design project with Adtech Global. To evaluateprocessor solutions, Adtech Global used the Video Decoding Workload AnalysisTool, a benchmarking software tool co-developed by Bosch and Adtech Global.This tool is used at Adtech Global to evaluate processor performance, measuredecoder performance and tune the decoder system to meet customer requirements.The PC-based test system provides high performance video streams to stressthe system under extreme workload scenarios, such as fast-switching videos thatchallenge a decoder. The tool represents a realistic workload, including decodingand CPU-based decryption algorithms in addition to processing incomingEthernet traffic on a GbE controller.Performance AnalysisAdtech Global conducted a trial that compared multiple CPU options, ultimatelyleading to the selection of a platform based on the 2nd generation Intel corei3 processor.

Bosch Case StudyAbout BoschSecurity SystemsBosch Security Systems, a division ofBosch Group, is a supplier of equipmentfor the global electronicprotection and communicationssystems industries. The Boschportfolio includes products andsystems for communications, videosurveillance, access control andintrusion and fire detection used bycustomers in commercial andindustrial environments throughoutthe world.The analysis tool automatically measures all relevant video resolutions and bitrates with one-percent accuracy. In the results shown here, all video streamsare decoded on the Intel Core i3 processor, without the involvement of a graphicsco-processor. The performance testing includes the Ethernet stack, enablingBosch engineers to optimize decode performance.The 2nd generation Intel Core i3 processor meets performance targets in smallfootprint device with an operating temperature range of 0˚C to 40◦C. in ahousing measuring less than DIN A5, and a maximum of 1 HU, allowing thedevice to be mounted directly on the back of a display.Adtech Global Business Development Manager Dan Davidovici explains onecomplexity of the project, “When it comes to handling four video streams with10 Mbits each, one of the biggest challenges was modifying video drivers tohandle multicasting. Intel engineers worked closely with Adtech Global to helpoptimize the video driver software.”For total data protection, each video communication channel can be independentlyAES-encrypted with 128-bit keys, once the encryption site license hasbeen applied. Encryption is performed in software.As Simon explains, “We see an increasing requirement for fully protecteddata transmission while performing CCTV over IP. So we are preparing forthat, including the use of the Intel ® processors integrated AES hardwareaccelerator, if needed in the future. With the Intel Core i3 processor, AESencryption at our data rates currently requires about 5-8 percent of CPUcapacity.”Adtech Global Company Snapshot• 120 Employees• Over 1,500 customers in20 countries• 12 years in customized hardware• ISO 9001:2008 certified• RoHS and WEEE compliantBosch VIP XD HD DecoderThe VIP XD HD decoder displays high definition and standard definition videofrom cameras and encoders using H.264 or MPEG-4 encoding at up to 30images per second over IP networks.It can decode and display four H.264 720p30 streams at 10 Mbps or two1080p30 streams at 10 Mbps, in addition to VCA metadata. Alternatively, it cansimultaneously decode six H.264 standard definition streams at up to 6 Mbpsfrom fast-moving auto dome cameras with the extremely high video clarity.For scenes with moderate levels of activity, the decoder can display up to 12streams of H.264 standard definition streams at up to 2.5 Mbps. The VIP XD HDdecoder can drive a HD display directly, a capability that makes it ideal forflat-screen monitor walls.31-888-ADTECH2 www.adtechglobal.com info@adtechglobal.com
