The ITU Radiocommunication Assembly considering that HDTV is defined as one of the picture formats in DTV standards; that compression technology is widely used and provides adequate picture quality in SDTV and HDTV applications not only for secondary distribution to the home but also for broadcasting studio equipment; that devices for HDTV signal compression have been developed by several integrated circuit manufacturers and are available economically in the market; that compression technology makes it possible to produce digital HDTV tape cassette recorders not only for studio production applications but also for field acquisition applications.
Band segmentation between radiocommunication services can be viewed as actually eliminatingsharing by creating sub-allocations.
This European Standard is applicable to open-path absorption measurements of 'concentration ~ path length'product using the Fourier transform infrared (FTIR) technique with an artificial radiation source. It is applicableto the continuous measurement of infrared active organic and inorganic compounds in the gaseous state inambient air using fixed tropospheric open paths up to approximately 1 km in length and provides a spatialaverage.
This part 1 of DIN EN 61996 specifies the minimum performance requirements, technical characteristics and methods of testing, and required test results, for shipborne voyage data recorder (VDR) installations as required by Chapter V of the International Convention for Safety of Life at Sea (SOLAS), as amended. It takes account of IMO resolution A.694 (17) and is associated with IEC 60945. When a requirement in this standard is different from IEC 60945, the requirement in this standard takes precedence. This 2nd edition incorporates amendments according to new IMO requirements included in IMO Resolution MSC.XXX (90).
This part of IEC 61996 specifies the minimum performance requirements, technical characteristics andmethods of testing, and required test results, for simplified shipborne voyage data recorders (S-VDRs) asrequired by IMO MSC.163(78). It takes into account IMO resolution A.694(17) and is associated withIEC 60945. When a requirement in this standard is different from IEC 60945, the requirement in thisstandard takes precedence.NOTE All text of this standard, whose wording is identical to that of IMO MSC.163(78) or A.861(20) is printed in italics, and theResolution and associated performance standard paragraph numbers are indicated in brackets.
This first part of IEC 62320 specifies the minimum operational and performance requirements, methods of testing and required test results for AIS Base Stations, compatible with the performance standards adopted by IMO Res. MSC.74 (69), Annex 3, Universal AIS.
This European Standard is applicable to open-path absorption measurements of 'concentration × path length'product using the Fourier transform infrared (FTIR) technique with an artificial radiation source. It is applicableto the continuous measurement of infrared active organic and inorganic compounds in the gaseous state inambient air using fixed tropospheric open paths up to approximately 1 km in length and provides a spatialaverage.
