With a few small changes, television was pretty much the same from 1955 to 2009. TVs got stereo, closed captioning, and parental controls, but that was about it.

These tables are: Master Guide Table (MGT) System Time Table (STT) Virtual Channel Table (VCT) Rating Region Table (RRT) Event Information Table (EIT) Extended Text Table (ETT) Data Event Table (DET)
Aug 7, 2013 · The document defines the standard protocol for transmission of the relevant data tables contained within packets carried in the transport stream multiplex. The protocol defined herein is referred to as Program and System Information Protocol (PSIP).
There are two main categories of information in the ATSC PSIP standard, system information and program information. System information allows navi-gation and access to the channels within the DTV TS, and program information provides the information necessary for efficient browsing and event selection.
Making digital and interactive television work depends up on the ATSC's new PSIP standard. This book, written by one of the standard's primary architects, annotates and explains the complex standard document, breaking it down into practical, usable checklists and methods for broadcast, cable, satellite, and product design.
