What can I Watch That has Closed Captioning?

TV:
Pursuant to federal rules, broadcasters and video programming distributors, like Comcast, are required to provide Closed Captioning for most English and Spanish language video programming shown on TV.

Keep in mind, however, that not all video programming is subject to the Closed Captioning rules. For example, advertisements of less than five minutes are not considered video programming subject to the Closed Captioning rules. In addition, there are exemptions for certain programming or networks, including Public Service Announcements, programming on new networks, locally produced educational programming and programming distributed from between 2:00 AM and 6:00 AM.

For more information on how to enable and disable Closed Captioning, see How to Enable Closed Captioning on Different TVs and Comcast Devices.

Starting on September 30, 2012, video programming owners and video programming distributors must begin to provide certain IP-delivered programming with Closed Captioning. Specifically, full-length, pre-recorded programming that has already shown on TV with Closed Captioning and that is not significantly edited for Internet distribution must contain captions when shown online. The deadlines to include Closed Captioning in live programming and programming that has been edited for Internet are in 2013. Finally, certain content - such as video clips, outtakes and consumer generated media - are not covered by the new online Closed Captioning requirements, and this content will most likely not contain Closed Captioning.

What is the Difference Between Closed and Open Captions?

Closed Captions refer to captioning data that is carried along with the video content and can be decoded and displayed on television set or decoded by the set-top box when activated by the customer. In some scenarios, captions are decoded and displayed on a television set, and in other scenarios the set-top box decodes the captions and then sends them to the television set to be displayed along with the video.

Open Captions are part of the video content and therefore visible to all viewers.

What is the Difference Between Standard Definition (SD) and High Definition (HD) Captions?

Standard definition Closed Captioning will appear on the TV screen with white letters on a black background. This type of Closed Captioning can be turned on and off via your HD set-top box or via your television, depending on your method of connection.

Closed Captioning on high definition channels may have additional settings you can control. With an HD-capable set-top box, you may be able to change the appearance of the font, text size, text color and even background color of Closed Captioning. These additional features are accessible via the caption menu of your HD set-top box (or your TV if you are not using a set- top box), and only available if the HD channel provider creates captioning in this format.
