Basics of Video: From Simple Analog to HDTV
نویسنده
چکیده
Video signals can be divided into two categories; analog and digital. Both use a variety of standards, formats, and available interfaces. Analog video had been the broadcast standard in the United States since it’s inception, however, in 2009 it was fully replaced by digital video broadcasting. Nonetheless, analog video is still used in many systems today. One good example is closed circuit security systems. On the other hand, the market’s transition to flat panel televisions has enjoyed the rapid growth, availability and superior image quality of digital video.

This paper summarizes results from an experiment whose goal was to assess whether the NTIA General Video Quality Metric (VQM) is an acceptable objective metric for measuring High Definition TV (HDTV) video quality. The HDTV subjective test that was performed to evaluate the NTIA General VQM contained 60 30-second video clips that were rated using the Single Stimulus Continuous Quality Evaluatio...
متن کاملHd Production Codecs
The introduction of HDTV in Europe requires that broadcasters renew their production equipment. Whilst HDTV equipment in the past has targeted tape-based solutions, the user requirements for modern HDTV production workflows are file-based, non-linear and non-real-time – with shared access via networks and servers – and, last but not least, they have to be cost-effective. These requirements put ...
متن کاملSubjective quality evaluation of the upcoming HEVC video compression standard
High Efficiency Video Coding (HEVC) is the latest attempt by ISO/MPEG and ITU-T/VCEG to define the next generation compression standard beyond H.264/MPEG-4 Part 10 AVC. One of the major goals of HEVC is to provide efficient compression for resolutions beyond HDTV. However, the subjective evaluations that led to the selection of technologies were bound to HDTV resolution. Moreover, performance e...
