An intraframe video compression scheme is used to compress video on a frame-by-frame basis with the discrete cosine transform (DCT).Ĭlosely following the ITU-R Rec. The IEC standards are available as publications sold by IEC and ANSI.ĭV uses lossy compression of video while audio is stored uncompressed. Part 2 describes the specifics of video systems supporting 525-60 for NTSC and 625-50 for PAL. These standards define common features such as physical videocassettes, recording modulation method, magnetization, and basic system data in part 1. The original DV specification, known as Blue Book, was standardized within the IEC 61834 family of standards. In the 2020s, DV codecs are still sometimes used when dealing with legacy standard definition video. Additionally, as manufacturers switched from interlaced to superior progressive recording methods, they broke the interoperability that had previously been maintained across multiple generations of DV and HDV equipment. In the 2010s, DV rapidly grew obsolete as cameras using memory cards and solid-state drives became the norm, recording at higher bitrates and resolutions that were impractical for mechanical tape formats. In 2003, DV was joined by a successor format called HDV, which used the same tapes but with an updated video codec HDV cameras could typically switch between DV and HDV recording modes. DV is sometimes referred to as MiniDV, which was the most popular tape format using a DV codec during this time. In the late 1990s and early 2000s, DV was strongly associated with the transition from analog to digital desktop video production, and also with several enduring " prosumer" camera designs such as the Sony VX-1000. Users can employ analytics that detect people and objects - including cars and bikes, line crossing, loitering detection and face detection.DV refers to a family of codecs and tape formats used for storing digital video, launched in 1995 by a consortium of video camera manufacturers led by Sony and Panasonic. With this approach, small-to-medium businesses can maximize the value of their existing investments and take a proactive approach to enhance security and safety. Users can deploy additional boxes to expand their systems. The box can connect to existing network video recorders (NVRs). The AI box allows accurate and multiple analyses from just a single camera without need for calibration. The DV-1304-A from IDIS is an NDAA-compliant add-on box that provides AI video benefits without the need to upgrade existing security cameras. The background picture-in-picture display option allows operators to monitor specific cameras while completing other tasks. This feature provides operators with a map-based overview of cameras and devices. XProtect includes more situational awareness capabilities with smart maps in the mobile clients. These tools improve operator efficiency and communication, enabling operators to easily share bookmarks and collaborate on video data analysis. Operator collaboration tools have enhanced features such as bookmarks sharing, background picture-in-picture and native screenshots in the mobile clients. Milestone XProtect users can now access video data with greater ease and efficiency in the solution’s latest version. Hailo-15 vision processors are engineered to consume very little power, making them suitable for IP cameras and enabling the design of fanless edge devices. Hailo-15 offloads cloud analytics to save video bandwidth and processing while improving overall privacy due to data anonymization at the edge. The added AI capacity can be utilized for video enhancement and better video quality in low-light environments, video stabilization and high dynamic range performance. The solution has been used in city security, manufacturing, retail and transportation sectors. Hailo-15 vision processors integrate directly into cameras to recognize real-time emergencies, such as broken machinery, trespassers and lost/unaccompanied children. The solution is designed to prevent false alarms by recognizing objects near the perimeter to determine if they’re a threat. The wireless system means there’s less equipment involved with installation, and the solution can work even with complicated permitting limits. The platform utilizes a private wireless network that covers large areas. The solution uses a combination of cameras and AI image detection. The solution offers constant threat detection for airports, warehouses and manufacturing facilities. The solution comes as a partnership with Axis platforms and Evolon camera applications. Betacom PSS is an AI-powered perimeter surveillance solution.
