Have you ever heard of DVB or ATSC and wondered what they are? If so, you’re not alone. These two systems are important standards for digital television broadcasting, so it is important to know the difference between them. Let’s take a look at what each system is and how they differ.
DVB (Digital Video Broadcasting) is an international standard for digital television broadcasting that was created by the European Telecommunications Standards Institute (ETSI). The most popular version of this standard is DVB-T, which stands for Digital Video Broadcasting – Terrestrial. This system is used in many countries around the world, including Europe, Asia, and Australia. It supports both SDTV (Standard Definition Television) and HDTV (High Definition Television).
ATSC (Advanced Television Systems Committee) is a North American digital television broadcasting system developed by the ATSC in 1982. This system is mostly used in the United States but can also be found in Canada, Mexico, South Korea, Honduras, El Salvador, Nicaragua, Costa Rica and some parts of South America. Similarly to DVB-T it supports both SDTV and HDTV broadcasts.
The main difference between these two systems lies in their transmission methods. DVB-T uses terrestrial radio waves to transmit signals while ATSC uses 8VSB modulation technique which transmits signals over UHF or VHF bands using an antenna instead of a satellite dish or cable connection like other TV broadcast systems do. Furthermore, while DVB-T only supports MPEG2 video format for SDTV broadcasts and MPEG4 AVC/H.264 format for HDTV broadcasts; ATSC can use all three formats – MPEG2 video format for SDTV broadcasts; MPEG4 AVC/H.264 format for HDTV broadcasts; and H265/HEVC format for Ultra HD 4K broadcasts making it more versatile than its European counterpart.
Both DVB-T and ATSC are two popular standards used worldwide for digital television broadcasting but there are some key differences between them that make them suitable to different areas of the world depending on their transmission methods as well as video formats supported by each system. Understanding these differences will help you decide which one will best suit your needs when setting up your own digital TV network whether it’s at home or commercially broadcasted online!
