Question: What compression method is part of the CAB format used by one of the original partners in the TV channel that hosts Rachel Maddow's show?

Knowledge 1: The Rachel Maddow Show
The Rachel Maddow Show (also abbreviated TRMS) is a daily news and opinion television program that airs on MSNBC, running in the 9:00 pm ET timeslot Monday through Friday. It is hosted by Rachel Maddow, who gained a public profile via her frequent appearances as a progressive pundit on programs aired by MSNBC. It is based on her former radio show of the same name. The show debuted on September 8, 2008. [SEP] Knowledge 2: MSNBC
MSNBC is an American news cable and satellite television network that provides news coverage and political commentary from NBC News on current events. MSNBC is owned by the NBCUniversal News Group, a unit of the NBCUniversal Television Group division of NBCUniversal (all of which are ultimately owned by Comcast). MSNBC and its website were founded in 1996 under a partnership between Microsoft and General Electric's NBC unit, hence the network's naming. Although they had the same name, msnbc.com and MSNBC maintained separate corporate structures and news operations. msnbc.com was headquartered on the Microsoft campus in Redmond, Washington while MSNBC operated out of NBC's headquarters in New York City. Microsoft divested its stakes in the MSNBC channel in 2005 and in msnbc.com in July 2012. The general news site was rebranded as NBCNews.com, and a new msnbc.com was created as the online home of the cable channel. [SEP] Knowledge 3: Data compression
The Lempel–Ziv (LZ) compression methods are among the most popular algorithms for lossless storage. DEFLATE is a variation on LZ optimized for decompression speed and compression ratio, but compression can be slow. DEFLATE is used in PKZIP, Gzip and PNG. LZW (Lempel–Ziv–Welch) is used in GIF images. Also noteworthy is the LZR (Lempel-Ziv–Renau) algorithm, which serves as the basis for the Zip method.[citation needed] LZ methods use a table-based compression model where table entries are substituted for repeated strings of data. For most LZ methods, this table is generated dynamically from earlier data in the input. The table itself is often Huffman encoded (e.g. SHRI, LZX). Current LZ-based coding schemes that perform well are Brotli and LZX. LZX is used in Microsoft's CAB format.

Drift: The Unmooring of American Military Power is a 2012 book by Rachel Maddow. Her first book, "Drift" explores the premise that the manner in which the United States goes to war has gradually become more secretive and less democratic. In "Drift", Maddow examines how American declarations of war have incrementally shifted from being congressionally approved to being centralized in the hands of the American president. The book's scope spans from the Vietnam War to the wars in Iraq and Afghanistan.
