To form the basis of future workings with security dealers and integrators, Video Stream products unify video surveillance analog and internet protocol (IP) worlds thereby enabling higher resolutions, convergence onto existing IP cabling infrastructure, eases routing over long distances especially on multi-building sites, reduces space requirements, enables progressive scanning rendering clearer images, supports different streaming media and compression formats to relieve transmission bandwidth and data storage requirements (MJPEG, MPEG4, H.264) and provides a thin transport layer for remote storage.
The cathode ray tube (CRT) monitors of the 1980s followed closely by modern liquid crystal displays (LCDs), plasma display panels (PDPs) and digital light processing (DLP) systems employ technology capable of updating the entire image in a single pass, known as progressive scanning. Current standards for high-definition television (HDTV) include the transmission of progressively-scanned 1280 (w) x 720 (h) images; a format known as 720p, and 1920 (w) x 1080 (h) images; known as 1080p.
Features include a wider field of view, progressive scanning mode, smart alarm activation, advanced communication capabilities for remote management and storage, and simple operation.
The result is progressive scanning with 25 evaluations per second and 6 m/sec object transport speed.
This television boasts 1,920-by-1,080 progressive scanning resolution, built-in digital ATSC tuner and CableCARD compatibility, 176-degree viewing angle and the Anynet chip.
Purchase an HD tuner to view special HD broadcasts (like the last Olympics) or just enjoy a crisper view with the TV's progressive scanning. If you're ready to worship at the video altar, it's time for wide-screen.
Progressive scanning and flexible image capture triggering enable codes in motion to be read reliably.
But MPEG-1 includes no concept of interlaced scanning; every picture or frame contains all the lines that make up a complete image (this is the so-called sequential or progressive scanning used by computers to make text more readable).
The 70-inch plasma television (model PS70X4H) is 4 inches thick, features 1,080-line progressive scanning and uses a DVI digital port.
