How do you pirate DVD......................................... Subject: I have seen DVD to pirated VCD transfers From: mengshi@pc.jaring.my (Lim Meng Shi) Date: 1997/11/16 Message-ID: Newsgroups: alt.video.dvd [More Headers] Knowng what has been said about the copy protection scheme of DVDs, I was quite surprise to discover that there are quite a few DVD to VCD pirated transfers already available here in Malaysia! I have seen The Fugitive on such a transfer. The disc even started with the blue DVD logo and there were no evidence of the oft described Macrovision effects. Total Recall was the other title that I saw but I didn't get to see it. I'm not supporting pirates but it's occurence is inevitable here. What I want to know is how did they bypass the anti-pirates features of DVDs? Subject: Could this be a DVD to VCD transfer? From: mengshi@pc.jaring.my (Lim Meng Shi) Date: 1997/11/16 Message-ID: <346dd30e.2498292@news.jaring.my> Newsgroups: alt.video.dvd [More Headers] I just saw a pirated copy of Blade Runner (Director's Cut) on VCD but I'm not quite sure if it is mastered from LD or DVD? Could it have been from DVD (despite the anti-copy thing) because the VCD had English subtitle that was actually WITHIN the screen shot (wide-screen). I have seen some VCDs that were mastered from LDs which have subtitles (and captions) that are usually below the screen-shot. Does DVDs usually have subtitles within the screen shot? BTW, the above pirated VCD has intermittent high-pitched cracking noise at irregular intervals. This was played on a system using Dolby Stereo only - no DD or DPL. Is this an anti-pirate thing or just some mastering flaws? The picture is very clear. The cover also had the DVD logo printed but as you know these pirates can print anything they want. Has someone managed to defeat the copy protection scheme? Does anyone know if Bladerunner - Director's Cut was actually released on VCD (non-pirated original)?

Byte article on CUBE's DVx: Sorry David. I had planned on posting to this board as well as that blurb on Innovacom, but you are too quick :) How much is a DVx chip anyway? Sorry CUBEites if the info below has already been discussed. I've rejoined the CUBE shareholders just recently and have only read the last 50 or so messages. Here is an interesting part of the article that describes the scalability of the encoding chip (DVx): "To encode high-resolution formats such as HDTV, multiple DVx processors can operate in parallel to divvy up the processing task. Previously, video-processing chips were interconnected by a globally shared bus. However, as the number of chips increases on the shared bus, it reaches the limit of the bus's bandwidth. This prevents further scaling of performance. Instead, the DVx uses a point-to-point architecture that scales directly with the number of chips. The DVx chip's inter-process communications (IPC) channels can be interconnected to build multi-processor arrays, as shown in the figure above [fig shows point-to-point communications method using master/multiple-slave]. Through the IPC ports, multiple DVx chips coordinate processing operations so as to encode all proposed digital HDTV formats. Two DVx chips can encode the 525P format, and eight to 10 chips are necessary to encode an HDTV 1080I format. (It takes only two DVx chips to decode all HDTV video formats.)"

Pioneer proposes DVD-RAM standard. The COMDEX news is rolling in................ Pioneer Proposes DVD-R/W Standard TOKYO--(BUSINESS WIRE)--Nov. 17, 1997--Pioneer Electronic Corp. announced its development, in collaboration with Pioneer Video Corp., of a new DVD-R/W system based on DVD-R specifications. Pioneer proposed this system to the DVD Forum Working Group for standardization on October 27, 1997. Pioneer New Media Technologies plans to market DVD-R/W products domestically once the standard is approved. DVD-R/W systems are rewritable and achieve this characteristic by using a phase-change alloy material in the recording layer of the disc. An equal signal quality to DVD-Video and DVD-ROM has been obtained by improving the reflectivity ratio in physical characteristics, short-recorded pit playback characteristic, and also served signals of the recorded disc. This recording format complies with the DVD-R standard and can be played-back on existing DVD-Video players and DVD-ROM drives. With this newly developed technology, DVD applications for authoring and file recording can benefit from rewritable capabilities. The DVD Forum Working Group will examine the system for publication as a standard. DVD-R/W systems will have the same record/playback physical characteristics (user data capacity of 3.95 GB/side) as the DVD-R Version 1.0 standard. The same operations can be run as DVD-Video and DVD-ROM discs containing the same quantity of data. TDK Inc., Mitsubishi Chemistry Inc. and Hitachi Maxwell Inc. will support media development, and JVC Inc. will support the application development for the new system.
