DPP Technical Delivery Standards DPP TECHNICAL SPECIFICATION FOR DELIVERY OF SD COMMERCIALS & SPONSORSHIPS TO CHANNEL 4 SALES This document is a complete guide to the common technical specification, agreed by ITV, IMD and Adstream, and Channel 4 Sales (for Channel 4, and on behalf of BT Sport, Box TV and UKTV.) Version 1.0 This document is a complete guide to the common technical specification agreed by Channel 4 Sales, ITV, BT Sport, IMD, and Adstream. The first four pages of this document outline parts of the specification that are unique to Channel 4 Ad Sales The main body of the document outlines the specification as adopted by the above parties. The Specification includes: Technical Specifications, i.e. the technical production methods which must be used, and the parameters which all material must meet to be acceptable by the broadcasters. Picture and Sound Quality requirements, which also form a binding obligation on producers of material. Assessment of quality is by nature subjective, and is highly dependent on the nature of the commercial or sponsorship. Some of the Quality Requirements are expressed in relative terms (“reasonable”, “not excessive” etc.), and it will be necessary to make a judgement as to whether the quality expectations of the intended audience will be fulfilled, and whether the broadcaster will feel that value for money has been achieved. Delivery Requirements, which specify the form and layout of the material. Sponsorship Delivery This Technical Specification outlines the full details for SD Commercial delivery as well as relevant elements for SD Sponsorship material, however it must be noted that Sponsorship clock numbers, file naming conventions and approval processes differ from commercials and are broadcaster- specific. Please see the broadcaster section of this specification for sponsorship delivery details. Material submitted for transmission must satisfy the IMD/Adstream Quality Control process. Material failing the QC process may be rejected and returned to the supplier for repair. Please ensure you are using the current version of this document, available at: https://www.channel4sales.com/planning-and-buying/Specs/on-air-specs-and-delivery/ Page 2 of 19 UK Version 1.0 – April 2015 Channel Four 1.0 – June 2015 COMMERCIALS: Every commercial submitted for transmission must satisfy a Quality Control process outlined by the parties above. Any commercial failing the QC process may be rejected and returned to the supplier for repair. Please ensure you are using the current version of this document, available at: https://www.channel4sales.com/planning-and-buying/Specs/on-air-specs-and-delivery/ For any queries relating to the specification and delivery of copy please contact your Traffic Manager: Traffic Kim Wakes – [email protected] 020 7306 8264 Traffic Manager Matt Gustard – [email protected] 020 7306 8266 Deputy Traffic Manager Normal route for delivery to Channel 4 Ad Sales: The Producer gets the copy cleared for broadcast by ClearCast. The Producer is then responsible for sending the file to Adstream or IMD. Once Adstream or IMD have received and completed the Q.C. for the copy, they deliver it to video servers based at the play-out providers for all channels listed. SPONSORSHIPS: IDENTIFICATION: Sponsorship copy is identified by unique clock numbers, obtained from C4 Sponsorship Department Account Managers. Without this number, the material will not be transmitted. For File-delivered Copy: FILENAMES should follow the unique Clock Number assigned to it, in UPPERCASE, with the extension “.mxf” in lowercase. Allowable characters are ‘A-Z’, ‘0-9’, ‘-‘ & ‘_’ , so the underscore is used where a forward-slash might be referred to. Here is an example: C4S/HOTPOT16014/005 Becomes C4S_HOTPOT16014_005.mxf Page 3 of 19 UK Version 1.0 – April 2015 Channel Four 1.0 – June 2015 SPONSORSHIP CONTACTS For any queries relating to the specification and delivery of SPONSORSHIP copy please contact one of the following: Traffic Kim Wakes – [email protected] 020 7306 8264 Traffic Manager Matt Gustard – [email protected] 020 7306 8266 Deputy Traffic Manager Clare Williams - Senior Airtime [email protected] 020 7306 5521 Executive Lisa Aldred - Senior Airtime [email protected] 020 7306 3741 Executive Matthew McCue Digital Media Manager [email protected] 020 7306 8352 BOX TV ONLY There is also a generic e-mail for all clients: [email protected] SPONSORSHIP - MUSIC REPORTING In addition to the delivery of your material to IMD or Adstream, there is an additional requirement for Channel 4 itself.

  • Application of Closed Circuit Television for Traffic Surveillance in Texas
    APPLICATION OF CLOSED CIRCUIT TELEVISION FOR TRAFFIC SURVEILLANCE IN TEXAS by William R. McCasland Research Engineer Texas Transportation Institute and Raymond G. Biggs Engineering Technician Texas Highway Department Research Report Number 139-11 Freeway Control and Information Systems Research Study Number 2-8-69-139 Sponsored by The Texas Highway Department In Cooperation with the U.S. Department of Transportation Federal Highway Administration TEXAS TRANSPORTATION INSTITUTE Texas A&M University College Station, Texas August 1971 ABSTRACT Closed circuit television (CCTV) has been used for surveillance of traffic and transportation facilities for many years. However, the num­ ber of operating systems are few bec,ause their effectiveness as a long term surveillance system has been suspect due to the inclusion of human observers in the surveillance loop. The use of CCTV for short intensive observations necessary to research and traffic studies has been success­ ful. The accelerating development of area wide traffic surveillance, control, and communications systems for urban areas will increase the interest in the use of CCTV as part of the surveillance system. There are four operating CCTV systems in Texas that are used for traffic sur­ veillance. Each system has different design and operating characteris­ tics. DISCLAIMER The opinions, findings, and conclusions expressed ,or implied in this report are those of the research agency and not necessarily those of the Texas Highway Department or the Federal Highway Administration. SUMMARY There are four closed circuit television systems in Texas that are designed and operated for traffic surveillance. Each system has different design and operating characteristics to satisfy the surveillance require­ ments.

Snyder June, 1971 Saint Louis, Missouri To produce a diversity of program material in a limited frequency spectrum, various multichannel, continuous-audio still-video, television transmission-systems, compatible to the existing systems, have been suggested and investigated. In this report, we categorize and describe these alternative systems and identify some of the system parameters and con­ straints. The issues explored are: the number of still picture channels that can be realized in a limited spectrum, the interrelation of various parameters with system con­ straints, and general system considerations. iii Preceding page blank TABLE OF CONTENTS No. Page 1.

COMMENTARY MUNICIPAL RIPOFF: THE UNCONSTITUTIONALITY OF CABLE TELEVISION FRANCHISE FEES AND ACCESS SUPPORT PAYMENTS David J. Saylor * I. AN INTRODUCTORY PARADE OF HORRIBLES Imagine the outcry if the Federal Communications Commission (FCC) announced that henceforth all television and radio licenses would be auc- tioned off to the highest bidder for each license term. The political justifica- tion for such a development could be quite straightforward: Uncle Sam needs the money to help reduce the national debt and save government pro- grams from the clutches of Gramm-Rudman.' The purported legal ration- ale for this radical departure from current practice would be that the public, i.e., the federal government, owns the air space and is entitled to get fair market value for renting the airwaves to broadcasters. Or, consider this frightening scenario. Suppose the mayor and city coun- cil of Washington, D.C.
