Provides television receiver manufacturers with the technical specifications and requirements of digital television receivers in order to achieve successful reception from free-to-air DTTB transmissions that comply with the Australian DTTB transmission Standard AS 4599.1 (including current Amendments).

This Standard defines both essential and optional requirements for DVB-T compliant digital broadcast television receivers for Australia with the capability of receiving Standard Definition television and optionally High Definition television via terrestrial broadcasting services. Other optional features include interactivity, datacasting services, surround sound, multi-lingual and appropriate interfaces for ancillary equipment. Specifications for subscription/pay services should be obtained from the operators of those services although specifications for the possible addition to a receiver of a Conditional Access system or other features are included. See Appendix G for details on 50 Hz HD and SD scanning and interface parameters. See Appendix H for receiver functional design issues that have attracted attention since the commencement of transmissions. See Appendix I for abbreviations and a glossary of terms used in this Standard.
