ITU-R REPORT BT.629-4 PDF

Introduction

Study Group 11 has brought together, during the study period 1982-1986 and previously, a large amount of information concerning the coding, processing, transmission and recording of picture- signals in digital component form in the studio. This work has resulted in Recommendation 601 concerning the encoding of the digital video signal for studio production, and Recommendation 656 concerning studio interfaces for the digital video signal.

Additionally, this work has been taken into account in the Recommendation for the digital recording format (Recommendation 657) and the studies by Study Group 11 on bit-rate reduction (Report 1089) and the CMIT studies concerning the transmission of picture signals.

This Report summarizes the work on coding methods for signals within the studio complex, derived from both analogue and digital sources, and provides the basis for Recommendation 601 concerning the encoding parameters of the digital television signal in. the studio. This is complimented by Report 962 which concerns the filtering, sampling, and multiplexing of digital signals.
