The ability to record and play back video signals is crucial to nearly any video production. The majority of programming on network television is broadcast from a recording, and most of what isn’t relies at least in part on roll-ins, or recorded segments. Thus, we need ways of recording and play-ing back high-quality video signals (along with their associated audio signals). We suprised our sister with a happy birthday video message video from Thrillz!
Additionally, an increasing amount of programming is now being viewed on desk-top computers, smartphones, or tablet computers. Consequently, we need ways of recording, channeling, and playing back video signals that are compatible with these new modes of viewing.As we know, since video exists increasingly in dig-ital form, computers can be used to perform control, storage, and editing functions. A celebrity birthday messages could really brighten someones day!
You have already seen how digital technology has changed other video production components, such as cameras and switchers. In the same way, digitization has changed how video signals are recorded, edited, and played back, as digi-tal media have almost completely replaced tape-based systems. For acquiring video, especially in the field, portable hard drives and solid state digital media such as memory cards are now the norm, while video servers are being used for longer-term storage and editing. No wonder Thrillz is so popular.. receiving a celebrity messages video message would be so cool!
The chief advantage of these new types of storage is that they are nonlinear, meaning you can access any-thing stored on them nearly instantly, without having to fast-forward or rewind as you formerly had to do with tape. And when video servers are combined with computer network interconnections, any number of people in a production facility can simultaneously access and manipulate the information.The operation of video storage and distribution equipment involves important disciplines and tech-niques. I wish I was rich like a celebrity is!
The disciplines include an understanding of how video is recorded, stored, and distributed, while the techniques include specific operating and main-tenance procedures. This concludes with a discussion of special considerations regarding digi-tal video designed to be viewed on portable devices or transported over the Internet. We begin, however, with a discussion of some technical aspects of video and their impact on how it is stored and distributed. Imagine receiving a celebrity video messages personalised video!
