ITU-T Z.322 FRENCH-1988 视觉显示终端的性能

This Recommendation describes some of the capabilities which are important to the user and which are commonly available on interfaces based on VDTs. It is not an exhaustive list of capabilities. The use of additional capabilities, not covered in these Recommendations, is not precluded. Not all of the capabilities described need be present on a given system. Graphics capabilities are for future study and are therefore not considered in detail in these Recommendations.

ANSI S4.28-1984 采取脉冲代码调制的专业数字声频的应用.优选取样频率

Covers the use of certain preferred sampling frequencies in applications where there is a need for interchange of high fidelity digital audio programs with a minimum of transcoding complexity. Applications where such interchange may occur include, but are not limited to, master tape recordings (audio alone, and audio with video), submaster tape recordings prepared for transfer to a consumer product format, studio signal processing, and the point-to-point transmission of broadcast signals over satellite or terrestrial networks. This standard does not cover sampling frequencies for narrow band audio applications, such as voice-quality transmission links, or processing devices in which both the input and output signals are in an analog format, even if such signals are ultimately used for interchange of program.

BS 4793:1972 规定电视摄像机透镜光学性能的推荐标准

Covers zoom lenses, variable focal length lenses and single focal length lenses, used in either black-and-white or colour reproduction systems. These recommendations adopt the optical transfer function (OTF), or more specifically its modulus, the modulation transfer function (MTF), as the method of assessment and specification of image quality. Covers the performance of lenses as a complete optical unit but does not deal with the performance of individual component parts.
