DTS Surround sound for Playstation 3
Digital Theatre Systems have announced that the DTS Coherent Acoustics Surround sound format will be a "mandatory audio technology" for blu-ray discs, which Sony recently confirmed will feature as the medium for the PlayStation 3.
Given the rivalry, Dolby is also more or less certain of supporting the Blu-ray disc format - hopefully giving Sony supporters some much needed Dolby Digital 5.1. Whatever happens, PS3 should be well equipped for surround sound options.
Although DTS is probably lesser known than Dolby's Digital and Pro Logic II solutions, it's nevertheless respected in the DVD sector and a number of PS2 games including Grand Theft Auto: Vice City support it, although Pro Logic II now seems to be more prevalent.
