It does not attempt to advise on the relative merits of loudspeaker monitoring and headphone monitoring, nor on the many other aspects of importance in headphone selection such as cost, comfort, durability, repairability, feedback susceptibility, electrical impedance, electro‑acoustical efficiency, consistency between units, non-linear distortion and maximum sound level. Recommendation ITU-R BS.775 – Multichannel stereophonic sound system with and without accompanying picture, contains the following information: – standard geometry for loudspeakers and listening position; – specification for 5/2/5 channel encoding/transmission/decoding system which maximizes compatibility with 2-channel and single-channel systems; – an optional listening arrangement with enhanced surround sound field coverage using three front loudspeakers and four surround loudspeakers. (...) Recommendation ITU-R BS.646 – Source encoding for digital sound signals in broadcasting studios, contains operating parameters and performance guidelines for analogue to digital conversion in sound equipment. (...) This Recommendation is intended as a guide to selection and assessment of performance of digital sound production equipment and digital sound production systems for broadcasting.

(...) NOTE – ITU-R Recommendations can be found at the following address: http://www.itu.int/ITU-R/publications/rec/index.asp Guide to ITU-R Recommendations on programme sound recording Analogue programme sound recordings • Recommendation BR.408 “International exchange of sound programmes recorded in analogue form” specifies the audio tape width, the recording speed and the recording characteristics for the international exchange of analogue sound programmes. (...) This Recommendation analyses three cases, namely: – when it is desired to derive a monophonic sound signal for conventional monophonic television emission; – when it is desired to derive a stereophonic sound signal for stereophonic television emission; – when it is desired to carry the original stereophonic film sound with matrix encoding of surround sound through the television emission chain. • Recommendation BR.1422 “Operational practices for television use of film soundtracks encoded with noise reduction and matrix surround” provides specifications similar to those in Recommendation ITU‑R BR.1287, but it focuses them on the exploitation of the various versions of Dolby companding and matrix encoding that can be found on analogue soundtracks of current feature films. _______________ C:\DOCUME~1\laurent\LOCALS~1\Temp\FrontPageTempDir\progr-sound-rec.doc (168367) 14.10.03 08.06.04 C:\DOCUME~1\laurent\LOCALS~1\Temp\FrontPageTempDir\progr-sound-rec.doc (163367) 14.10.03 08.06.04

ITU-R BT.1359-1 Relative timing of sound and vision for broadcasting (5 pages) This document recommends maximum operating limits for delay between sound and picture. These delays arise from separation of sound and picture during processing or transmission. (...) These systems are generally based on, or are designed for maximum compatibility with, existing 525-line and 625-line systems using NTSC, PAL or SECAM colour encoding systems. ITU-R BT.796 Parameters for enhanced compatible coding systems based on 625-line PAL and SECAM television systems (5 pages) This document contains a set of target areas for improvements to be made in existing analogue colour television systems without loss of compatibility with existing receivers: – picture enhancement techniques for: – wider aspect ratio; – reduced cross-effects between luminance and chrominance signals; – ghost cancellation; – increased resolution; – data signalling; – sound enhancement techniques for improved quality sound coding.
