8、mbership and the entertainment industry in technical standards related matters. The goal of the Program is to take a leading role regarding technology within the entertainment industry by creating standards, monitoring standards issues around the world on behalf of our members, and improving communi
9、cations and safety within the industry. ESTA works closely with the technical standards efforts of other organizations within our industry, including USITT and VPLT, as well as representing the interests of ESTA members to ANSI, UL, and the NFPA. The Technical Standards Program is accredited by the
10、American National Standards Institute. The Technical Standards Council (TSC) was established by ESTAs Board of Directors to oversee and coordinate the Technical Standards Program. Made up of individuals experienced in standards-making work from throughout our industry, the Committee approves all pro
11、jects undertaken and assigns them to the appropriate working group. The Technical Standards Council employs a Technical Standards Manager to coordinate the work of the Committee and its working groups as well as maintain a “Standards Watch” on behalf of members. Working groups include: Camera Cranes
12、, Control Protocols, Electrical Power, Event Safety, Floors, Fog and Smoke, Followspot Position, Photometrics, and Rigging. ESTA encourages active participation in the Technical Standards Program. There are several ways to become involved. If you would like to become a member of an existing working
13、group, you must complete an application which is available from the ESTAoffice. Your application is subject to approval by the working group and you will be required to actively participate in the work of the group. This includes responding to letter ballots and attending meetings Membership in ESTA
14、 is not a requirement, but there is a $100 a year participation fee for TSP membership. This is a flat rate, regardless of voting status or the number of working groups in which a person is a participant. You also can become involved by requesting that the TSC develop a standard in an area of concer
15、n to you. The Control Protocols Working Group, which authored this standard, consists of a cross section of entertainment industry professionals representing a diversity of interests. ESTA is committed to developing consensus-based standards in an open setting. Future Control Protocols Working Group
16、 projects will include updating this publication as changes in technology and experience warrant, as well as developing new standards for the benefit of the entertainment industry. 2016 ESTA iii Investors in Innovation The Technical Standard Program (TSP) is financially supported by ESTA and by comp
