In law enforcement breathalyzers are used to corroborate an officer’s observations of a person suspected of impairment. The courts know that not everyone has the same tolerance for alcohol. So a breathalyzer test alone isn’t sufficient to convict. But it can be used to reinforce the subjective impressions an officer may make based on less accurate means like following a suspect for a short period and field sobriety tests. More reviewers need to take the same kind of balanced approach to reviewing, as this MPEG-2 encoding offers yet more concrete evidence of why you simply can’t judge video by the codec used – not even a little. You will not find a VC-1 or AVC encoding from a film based source, much cleaner or more detailed than this.
Without the demands of maintaining higher levels of video noise, Sony could have pushed the bitrate lower. But, with 50GBs of storage they didn’t, instead opting to stick with their normal bit budget for MPEG-2, a variable average of roughly 25mbps, which equates to an image free of compression as well.
The PS3 has a 2x BD drive right?How fast can you read/write data on a Blu-ray disc?
According to the Blu-ray Disc specification, 1x speed is defined as 36Mbps. However, as BD-ROM movies will require a 54Mbps data transfer rate the minimum speed we're expecting to see is 2x (72Mbps). Blu-ray also has the potential for much higher speeds, as a result of the larger numerical aperture (NA) adopted by Blu-ray Disc. The large NA value effectively means that Blu-ray will require less recording power and lower disc rotation speed than DVD and HD-DVD to achieve the same data transfer rate. While the media itself limited the recording speed in the past, the only limiting factor for Blu-ray is the capacity of the hardware. If we assume a maximum disc rotation speed of 10,000 RPM, then 12x at the outer diameter should be possible (about 400Mbps). This is why the Blu-ray Disc Association (BDA) already has plans to raise the speed to 8x (288Mbps) or more in the future.
