A/49: Ghost Canceling Reference Signal for NTSC (for adjacent-channel interference or co-channel interference with analog NTSC stations nearby) A/52B: audio data compression (Dolby AC-3 and E-AC-3) A/53E: "ATSC Digital Television Standard" (the primary document governing the standard) A/55: "Program Guide for Digital Television" (now deprecated in favor of A/65 PSIP) A/56: "System Information for Digital Television" (now deprecated in favor of A/65 PSIP) A/57A: "Content Identification and Labeling for ATSC Transport" (for assigning a unique digital number to each episode of each TV show, to assist DVRs) A/63: "Standard for Coding 25/50 Hz Video" (for use with PAL and SECAM-originated programming) A/64A "Transmission Measurement and Compliance for Digital Television" A/65C: "Program and System Information Protocol for Terrestrial Broadcast and Cable" (PSIP includes virtual channels, electronic program guides, and content ratings) A/68: "PSIP Standard for Taiwan" (defines use of Chinese characters via Unicode 3.0) A/69: recommended practices for implementing PSIP at a TV station A/70A: "Conditional Access System for Terrestrial Broadcast" A/71: "ATSC Parameterized Services Standard" A/72: "Video System Characteristics of AVC in the ATSC Digital Television System" (implementing H.264/MPEG-4 as well as MVC for 3D television) A/76: "Programming Metadata Communication Protocol" (XML-based PMCP maintains PSIP metadata though a TV station's airchain) A/79: "Conversion of ATSC Signals for Distribution to NTSC Viewers" (recommended practice, issued February 2009) A/80: "Modulation and Coding Requirements for Digital TV (DTV) Applications Over Satellite" (ATSC-S) A/81: "Direct-to-Home Satellite Broadcast Standard" (not yet implemented by any services) A/82: "Automatic Transmitter Power Control (ATPC) Data Return Link (DRL) Standard" A/85: "Techniques for Establishing and Maintaining Audio Loudness for Digital Television" A/90: "Data Broadcast Standard" (for datacasting) A/92: "Delivery of IP Multicast Sessions over Data Broadcast Standard" (for IP multicasting) A/93: "Synchronized/Asynchronous Trigger Standard" A/94: "ATSC Data Application Reference Model" A/95: "Transport Stream File System Standard" (TSFS is a special file system for downloading computer files) A/96: "ATSC Interaction Channel Protocols" (interactive TV) A/97: "Software Data Download Service" (used by UpdateTV for upgrades and software patches in ATSC tuners) A/98: "System Renewability Message Transport" A/99: "Carriage Of Legacy TV Data Services" (for former analog supplemental services that used the vertical blanking interval lines, such as closed captioning and teletext) A/100: "DTV Application Software Environment - Level 1" (DASE-1) A/101: "Advanced Common Application Platform" (ACAP) A/103:2014: "Non-Real-Time Delivery" A/104: "ATSC 3D-TV Terrestrial Broadcasting" A/105:2015: "Interactive Services Standard" A/106:2015: "ATSC Security and Service Protection Standard" A/107:2015: "ATSC 2.0 Standard" A/110A: "Synchronization Standard for Distributed Transmission" (single-frequency networks) A/112: E-VSB (Enhanced Vestigal Sideband) A/153: ATSC-M/H In 2004, the main ATSC standard was amended to support Enhanced ATSC (A/112); this transmission mode is backwardly compatible with the original 8-Bit Vestigal Sideband modulation scheme, but provides much better error correction. ATSC-M/H for mobile TV has been approved and added to some stations, though it is known that it uses MPEG-4 instead of MPEG-2 for encoding, and behaves as an MPEG-4-encoded subchannel, inheriting 8VSB from the remainder of the channel.

Worked examples

Example 1 — a first encounter with List of ATSC standards

Start with the simplest possible case. Write down what List of ATSC standards claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of ATSC standards before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of ATSC standards ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of ATSC standards

In research: List of ATSC standards appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of ATSC standards in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of ATSC standards is common in secondary-school and first-year university syllabi. It links to neighbouring topics ATSC, Digital television, High-definition television, so understanding it makes those chapters shorter.
In everyday life: Look for List of ATSC standards outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
