The workflow of the
more modern broadcast applications
The resounding success of the video servers that inserted the
Commercial led to the generalization of its use in other
emission and production applications. One of the first of
these uses were in the reproduction of mobile backgrounds, either
as a feed to the switcher on the air or as a feed to a video wall in
camera. Then, as the price of storage in
disk was reduced, servers began to replace the
tapes for recording and playback of long-form content such as
syndicated programming. As the number increased
of emission applications, they began to be used as well
additional content sources (Figure 2). Links
Satellites became a power source, both
of extensive formats as well as non-local commercials. The
tools that had previously been suitable for trimming the
tape segments of the beginning and end or the tails of the
Individual commercials required additional capabilities for
locate and cut multiple commercials and segments in one
recording from a satellite feed.
With the increase in quantity of material recorded daily on the server, the companies Automation producers saw the importance of offering support for timed recordings in addition to control of router, satellite antenna and receiver control. The new sources for server content came to include non-linear editors along with their graphical boxes. Initially, these devices, such as VCRs and feeds satellites, transferred their content by digitizing real-time baseband video and audio.
In recent years there has been a considerable increase in the use of baseband file transfer. At the beginning, these digital media servers operated as individual units that received their content in the form of files but played it as a baseband in real time. Now, most can offer direct transfer of files to the servers, if the server is supported and the Integration interface can handle the process.
Also traffic systems have matured. Now the norm is the creation of lists of reproduction of commercials, without human intervention, through of a network connection between the traffic system and the system automation. In addition, most systems Traffic contemporaries uses automatic logging as-run created by the server or by the automation system that make up that register without operator intervention.
The archiving needs of the Early years have been simplified with the fact of storing or copy the original distribution tape. Any commercial that it was eliminated could be re-digitized in case it was would need it again though, as the content began to come from sources other than tapes, broadcasters looked for another solution for the file function. For some, this meant archiving true digital data using DVD-RAM or digital data tapes as storage; others considered that archiving on videotape Baseband was quite cost-efficient and technically efficient adequate, especially in light of the low generational loss in the serial digital domain. These two file models increased the requirements to be met by the automation and with the advent of content pools individual on the server and in the file, the manufacturers of automation expanded the variety of tools they offered for media management tasks.
Flow characteristics
emission work
At this point it is necessary to note that although the servers of
video advanced from the insertion of commercials to the
total transmission operation, the basic workflow
remained relatively the same for the following reasons:
- The workflow of transmission is decisive in that all the content and the processes for acquiring it are known without ambiguity.
- It has long periods of margin for the acquisition of the contents on pre-recorded content for playback is purchased with hours, or even days, of anticipation.
- It also has long periods margin for programming; programming for playback is set with hours, or even days, in anticipation of its transmission.
- Workflows transmission involve few streams of content that are overlap.
- Outside of technical problems, CGs, crawls, effects, and squeezebacks (retrograde compression of data) of image), the flow of content derived from the transmission operations originate from the flow of a device only.
The challenge of news
tape-based
Currently, almost all newsrooms work with
tape base. They are composed of a room computer system
of news and a number of individual devices including
VTRs, editors, internal routing and graphics units. The
portion of the tapes is expensive and prone to mechanical failure;
tapes are fragile, time-consuming
transfer them and can only be used by one person to the
time. By making a serious comparison with newsrooms
that work based on digital servers, which have
as a basis the news on tape, as is evident, support the
additional burden of both human and human inefficiencies
hardware, excessive costs, and reliability issues.
That said, the tape workflow has become
an integral part of the industry and, as such, is a source of
security for those who drive it.
