本公告（CTA-CEB16-B）为开发和实施消费电子产品提供指导 处理与纵横比信令、活动格式描述（AFD）和 酒吧数据。此类设备可通过创建最佳（或更理想）显示来响应该信号， 通过将该信号传递到模拟或数字输出，或准备数字记录。 CTA-CEB16-B审查了表示AFD、纵横比信息和条形图的标准化方法 各种模拟和数字标准清晰度（SD）和高清（HD）接口上的数据。每人 在各种传输显示格式中，CTA-CEB16-B提供了输出信号和 显示外观，考虑可能的解码器功能、缩放选项和用户 有关显示格式的首选项。

This bulletin, CTA-CEB16-B, provides guidance for the development and implementation of consumer devices that process information related to aspect ratio signaling, Active Format Description (AFD) and bar data. Such devices may respond to this signaling by creating an optimum (or more desirable) display, by passing this signaling through to an analog or digital output, or in preparation of a digital recording. CTA-CEB16-B reviews the standardized methods for representing AFD, aspect ratio information, and bar data on various analog and digital Standard Definition (SD) and High Definition (HD) interfaces. For each of various transmitted display formats, CTA-CEB16-B provides recommendations for output signaling and display appearance, taking into account possible decoder capabilities, scaling options and user preferences regarding display format.
