The Amateur Radio bands above 50 MHz can support computer-to-computer communications at speeds high enough to support multimedia applications. Multimedia in this case refers to voice, data and image communications.
One approach that has been extensively explored is an adaptation of IEEE 802® technologies, particularly 802.11b operating in the 2400-2450 MHz band, known as the "Hinternet."
Also under the HSMM umbrella has been an orthogonal frequency division multiplex (OFDM) system developed by John Stephenson, KD6OZH, and tested on the 6-m band.
The ARRL has an extensive catalog of books and materials related to Amateur Radio Articles.

ARRL Periodicals Index Search - This database contains the QST index from 1915 to the present and the QEX index from 1981 to the present. For QST issues from 1970 to the present, and some selected articles back to 1922 (when construction articles featuring tubes began in earnest), identifying keywords have been added to the technical articles. By entering keywords (HSMM or Multimedia) or combinations of keywords into the Title words: field, you may create dynamic bibliographies.
