Those located in Macau can start gearing up for a little HD in their lives, as Teledifusao de Macau (TDM) has just started internal testing of a trio of new channels. The new digital broadcasting stations should be opened up to the public during the Olympic Games, with Macau HD airing in high-definition and TDM / Canal Macau showing in SD. Initially, Macau HD will simulcast material from TDM, but it will be developed into a channel with its own identity in due time. Also of note, it's unclear whether any of the stations will actually be used to show Olympics coverage, but we doubt the mention would've been made otherwise.
