How to Guide Closed Caption Monitoring WFM6120/7020/7120 & WVR6020/7020/7120 Version 5.0.2 Software How to Guide Closed Caption Monitoring What is Closed Captioning? There are a variety of methods to add captioning to the program material depending upon the video format. CEA 608 standardizes the process of adding caption data to standard definition (SD) signal. This can be added as an analog signal to line 21 of the active NTSC signal as shown in Figure 1. The signal contains a clock and two data bytes which are transmitted on each field of the video signal (120 Bytes per second or 960 bits per second (bps)). Alternatively in SD-SDI (Serial Digital Interface) this analog signal maybe digitized as part of the active video or alternatively carried as an ancillary data packet within the video signal. For high definition (HD) a new standard was created for the addition of captions to the video signal which is standardized in CEA708.This captioning standard provides a wider range of captioning service while still maintaining backwards compatibility with CEA 608 and is carried an ancillary data packet within the HD-SDI signal. The DTVCC (Digital Television Closed Captioning) provides a maximum data rate of 9600bps. This increased capacity allows for the possibility of simultaneously providing captions in multiple languages and multiple reading levels. Figure 1. NTSC Line 21 Closed Caption Signal. The latest version of the WFM and WVR series firmware version 5.0.2 now supports the simultaneous decode of CEA 708 and 608 closed captioning, allowing the operator to monitor both data streams for compatibility. -

AT12: Closed Captioning on Video
Closed Captioning on Video – FAQ What does it really mean to create an “equal” viewing experience with captioning? Equal access requires that the meaning and intention of the material is completely preserved. That’s everything from making sure that you caption the sound effects and the dialogue, accents, the grammatical errors, etc. The goal here is to convey exactly what’s being communicated. In addition, there are times when you must edit the dialogue. This could be because somebody is speaking rapidly and there’s just not enough time to get all the words on the screen. Most video production teams have a policy where we edit dialogue to be shorter and simpler. We don’t want to edit out important vocabulary. We don’t want to change concepts. It needs to be an equal representation. What font and size are best for closed captions? For closed captioning on most video players like YouTube, the player itself is going to dictate the settings, so you’re not going to have control over that. The caption display is customizable by the viewer, and can be affected by screen resolution and even what browser they’re using to watch your video. But for standard-definition videos with open captions, we use Arial (a sans-serif font) and a font size of 22. For the high-definition stuff where the resolution is greater, we bump that up to 44. As a rule, you should consider 32 characters per line as a good rule of thumb when captioning. How would I create closed captions on YouTube? If your videos are hosted on YouTube, there are a number of ways to create your own captions directly in the YouTube editing interface. -

PBS Engineering Technology Advisory Committee ATSC 3.0 Position Paper
PBS Engineering Technology Advisory Committee ATSC 3.0 Position Paper Introduction The PBS Engineering Technical Advisory Committee (ETAC)* has created a working group focused on the pending ATSC 3.0 broadcast transmission standard and its impact on PBS member stations. The ETAC ATSC 3.0 Working Group is made up of Public Television station technology leaders with support from PBS. The current digital broadcast technology was developed in the early 1990s by a large group of industry professionals with overall leadership from the FCC Advisory Committee on Advanced Television Service and the Advanced Television Systems Committee (ATSC).* The standard was published in 1995 and then adopted by the FCC in 1996. In July of 1996, WRAL TV in Raleigh, NC became the first North American television station to broadcast a digital service. In time, the standard we now refer to as ATSC 1.0 was introduced across the country. With the demise of analog television broadcast, it became the operating standard in 2009. ATSC 2.0 was an enhancement of ATSC 1.0, adding new technologies such as advanced video and audio coding and new features such as second screen and Conditional Access. While ATSC 2.0 did become a standard, it was not widely adopted. Many of the capabilities 2.0 enabled, however, were used and expanded on in ATSC 3.0. Technology changes rapidly and the need for an advanced broadcast standard not hampered by the backwards compatibility restraints of ATSC 1.0 is clear. Given consumers’ rapid adoption of mobile and handheld devices for video consumption, it is clear that broadcasters need to adapt to meet current consumer demands and ensure scalability for future needs. -
