Bitstreaming of Dolby TrueHD and DTS-HD MA Supported in Slim Model


This was one of the new updates that wasn’t mentioned when the console was announced, but the console finally will be able to bitstream high definition audio to HD-capable receivers. This was something that I was hoping for when the original design came out, but it was only able to encode high definition audio sources through PCM 5.1 and 7.1 (which still sounded great). Apparently, the older model was incapable of it because the HDMI chip wasn’t compatible, hence why it had to encode it internally and send it through LPCM, so this wouldn’t even be possible with a firmware update. Shucks. In any case, the PS3 Slim is, indeed, able to decode truly lossless audio, so if you have a high end A/V receiver, you’ll finally be able to see those DTS-HD and TrueHD lights to shine! Before, with going through LPCM, there was always that chance that your audio equipment would interfere with that signal, causing some jittering and whatnot, but since it will now allow your HD receiver to decode it, you wouldn’t have to worry about it. Origin of news came from Engadget who, in turn, got it from a Japanese site.

    Right now I have a Sony DTS-EX 6.1 that doesn’t do HD audio streams, if I ever upgrade I will remember this.

    Stop me if I’m wrong, But I think this is the first Hardware upgrade/change that has been added to the PS3.

    well, there’s the 45nm process as well they’re using on the chips, which run cooler (and are smaller, of course). Other than that, though, yeah, this is about the only new feature on the system in terms of hardware capability

    They added Bravia Sync as well. Admittedly, that’s a very niche feature…

    I don’t fully understand the difference between bitstreaming and LPCM, but this sounds great. I’m planning to buy a new TV/receiver setup anyway (LOONG overdue upgrade), so this is good to know.
