The tester enables the testing of all tracked parameters (including jitter and error correction) at two times the reference velocity, which, combined with the track sweep measurement for open loop parameters, enables 2x-testing. In addition to the 2x testing functionality, the CATS B210 BD Pro 2x can test at 1x speed with the same level of measurement accuracy as the most used test equipment in the market, the CATS B100 BD Pro, AudioDev claims. This gives the tester 2x testing for production purposes and also reference class measurements at 1x speed, using the same tester.
The new CATS B210 BD Pro 2x is based on the latest version of AudioDev?s measurement board, designed with both reference testing at 1x and testing at 2x in mind from the start. The tester is also using the new version of the reference drive from Toptica Photonics, designed for testing at 2x speed as well as capable of tangential tilt compensation. By combining the new measurement board and the Toptica drive, AudioDev has been able to achieve a good correlation between measurements at 1x and measurements at 2x.
Format verification on BD stampers
AudioDev also announced a new function for its line of CATS BD-testers that enables the system to read the content from BD-ROM media. The encrypted content can then be fully verified against the BD-file structure and video specifications using the ImageAnalysis BD or ImageVerify BD from Eclipse Data Technologies.
The functionality, called Virtual Image Server, runs in the background of the CATS host application allowing the transaction of content at the same time as the operator runs tests. When the CATS test is done, the files required for the format verification has already automatically been transferred to the appropriate network location, ready for verification. During the regular CATS test, the Virtual Image Server communicates with the CATS host application and provides information about critical parameters (such as network connectivity). In case any critical parameters for the format verification are found to be outside the limits (such as a brief network failure) any damaged test area can be retested using the regular re-test function in the CATS software.
The Virtual Image Server can be used for CATS testers for both BD replicas and BD stampers, but it is for the stamper testers where the functionality really stands out. "When using the Virtual Image Server on a CATS BD-stamper tester, the customer can get the content verified without having to first produce sample discs on dedicated production lines. This saves valuable time and inventory" says Dan L?fgren, product manager for the CATS BD testers at AudioDev.
The system automatically handles stampers for both single and dual layer BD-ROM media, as the content from both stampers are needed to fully verify a dual layer disc. A key component that enables the Virtual Image Server is the ability to test and verify the ROM Mark, the mandatory watermark present on all BD-ROM media. Together with the recently released ROM Mark test function, the CATS BD stamper tester with Virtual Image Server enabled has the capabilities to supply the format testing tool, such as the ImageAnalysis BD and ImageVerify BD from Eclipse, with all the necessary information to fully verify the content.
The Virtual Image Server is available both as an upgrade for existing CATS BD testers on the market as well as an option for new testers. The Virtual Image Server is always included when purchasing a new CATS BD stamper tester.
Both the Virtual Image Server and the new 2x-tester products will be shown at the Media-Tech Expo event in Frankfurt, Germany, during the 19-21 of May.
