ATSC 1.0 vs ATSC 2.0 vs ATSC 3.0: TV Standards Comparison

This page compares ATSC 1.0, ATSC 2.0, and ATSC 3.0 TV standards, highlighting the key differences between them.

ATSC 1.0

Here are the features of the ATSC 1.0 standard:

• Supports a single bit rate of 19.4 Mbps.
• Provides coverage with 15dB CNR (Carrier-to-Noise Ratio) at rooftop antennas.
• Supports HDTV (High-Definition Television), multicast, and data transmission.
• TV and internet services were delivered separately to users.
• Allows HDTV and SD (Standard Definition) multicast.
• Uses 8VSB modulation.

ATSC 2.0

Here are the features of the ATSC 2.0 standard:

• Backward compatible with ATSC 1.0.
• Allows interactive and hybrid TV using internet protocols.
• Supports advanced video compression techniques.
• Supports advertisements.
• Enables Video on Demand (VOD) services.
• Allows storage of non-real-time content.

ATSC 3.0

Here are the features of the ATSC 3.0 standard:

• Broadcasting becomes part of the wireless internet. Broadband and broadcasting are merged.
• Delivers more bits per Hertz (bits/Hz), making it more spectrum efficient.
• Supports flexible bit rates and various coverage areas.
• Supports multiple simultaneous bit pipes with different choices for different broadcast services, including physical layer pipes (time), layered division multiplexing (power), and channel bonding.
• Allows UHD (Ultra High Definition) and/or HD multicast.
• Uses OFDM (Orthogonal Frequency-Division Multiplexing) to deliver a high data rate ranging from 28 to 36 Mbps (or higher) over a 6 MHz bandwidth.
• Supports a resolution of 3840 x 2160 at 60 frames per second (i.e., 4K UHD TV).
