Audio and Video Systems

CTA's Audio and Video Systems Committee develops standards, recommended practices, and related documentation for consumer systems whose primary function is presentation of audio or video and associated content. All are encouraged to join the Audio and Video Systems Committee and get involved in its activities. The Audio and Video Systems Committee is particularly interested in adding new members (called "users") who acquire audio and video products from those who create them.

CTA-861.7
Improvements to CTA-861-I

This document will include improvements to CTA-861-I. 

CTA-2010-C
Standard Method of Measurement for Powered Subwoofers

This standard defines a method for measuring the audio performance of subwoofers, both passive and powered. The standard is being revised in order to incorporate new rating methods and to make additional edits as needed.

CTA-2034
Standard Method of Measurement for In-Home Loudspeakers

This standard describes how to determine the frequency response, directivity, and maximum output capability of a residential loudspeaker. It is intended to determine the audio performance of a loudspeaker, not the loudspeaker’s ability to survive a given input signal. The standard is being revised to incorporate new rating methods and to make additional edits as needed.

CTA-2049-B
Determination of Small Network Energy Consumption

This standard defines procedures for measuring Small Network Equipment (SNE) energy consumption.

CTA-2054
Specifications for Selecting an Amplifier for Use with a Loudspeaker System

This standard will outline the performance attributes of a power amplifier in order to allow consumers / end-users to easily determine if a given amplifier is compatible with a given loudspeaker system.

CTA-2099-A
Standard Method of Measurement for In-Home Amplifiers and Loudspeakers

This standard describes how to determine the maximum output capability of loudspeakers, subwoofers, and amplifiers intended for use in consumer/residential applications. It also describes how to determine appropriate crossover frequency region for and between loudspeakers and subwoofers.

CTA-CEB32.8-C
Recommended Practice for ATSC 3.0 Television Sets, Application Runtime Environment

This bulletin makes recommendations related to the capabilities of ATSC 3.0 Television Sets as they relate to the handling of the Application Runtime Environment of ATSC 3.0 signals. The Application Runtime Environment includes Application Program Interface (API) descriptions that allow HTML5 applications to interface with ATSC 3.0 enabled devices for inclusion of an interactive ATSC 3.0 Service.

CTA-CEB32 Suite
Recommended Practice for ATSC 3.0

This bulletin makes recommendations related to functionalities and capabilities of ATSC 3.0 Television Sets as they relate to multiple subsystems (e.g. physical layer, logical layer, audio, video, captions, etc.)
