Generic bit-rate reduction coding of digital video signals for production for contribution for primary and secondary distribution for emission and for related applications
The ITU Radiocommunication Assembly considering a) that rapid progress has been made in bit-rate reduction coding techniques; b) that bit-rate reduction coding of digital video signals (e.g. LDTV, SDTV, EDTV, HDTV LSDI and UHDTV ** ) finds wide applications for production, for emission by terrestrial means and by satellite, for contribution, for both primary and secondary distribution by telecommunication and by CATV networks; c) that the large channel capacity required for the digital transmission and recording of UHDTV video signals may introduce problems that are both technical and economic, and it is desirable to reduce the bit-rate required by these signals to a minimum consistent with the necessary performance objectives; d) that the encoding methods adopted for digital video should have as many common characteristics as possible so as to simplify conversion between standards and also permit operating economies; e) that lossless 1 or perceptually lossless 2 bit-rate reduction coding may be desired particularly for studio applications; f) that there are advantages in having a generic bit-rate reduction coding in the various applications; g) that a number of compression families have been used for various television applications.
