The world's first full-featured video analyzer for MHL video interfaces transmits media content to high-definition devices via mobile devices. This application is no longer a future paradox, but has become a reality. That's why more and more smartphone and tablet manufacturers are turning to the new mobile HD video interface, MHL. Rohde & Schwarz now offers a compact, all-in-one solution that combines interoperability and application testing. Manufacturers of mobile phones and tablets will benefit from this solution: the new solution is simpler to use and more cost effective than traditional test equipment.
R&S VTE is a modular, scalable test platform for the development and quality inspection of video and audio equipment; the economical R&S VTS system is suitable for production lines. Both products support the MHL interface test module. The MHL interface supports the transmission of high-definition video and audio content. A typical application is to receive video over LTE on a smartphone or tablet, and then deliver high-definition images and audio to the HDTV via MHL.
R&S VTE and R&S VTS are all-system-in-one solutions that support MHL protocol testing and video and audio analysis. Video and audio parameters such as InfoFrames and HDCP can be analyzed in real time. It can be used to test inputs and outputs and support conformance testing of MHL system protocols. R&S VTE has an audio and video check function to judge the deterioration of the decoded video signal of the mobile device by detecting and objectively analyzing different images.
The R&S VTE is a comprehensive 3U height, 1/2 19" wide compact instrument; the economical R&S VTS is only 1U high. Both products have built-in processors and no external computer control. The device supports remote Control, economical and energy-saving, R&S VTE has a unique artistic touch screen operation. Rohde & Schwarz offers automatic test software, with MHL test options, which can be easily automated. Users can also customize the test process. And output a test report.
The modular design provides users with a more efficient solution that flexibly meets test requirements and reduces costs. R&S VTE can support 3 different test and test modules. In addition to the MHL test module, Rohde & Schwarz will also provide HDMI, analog video and audio, RF and other test modules.
High-end AV interface test platform for consumer electronics development Current consumer electronics such as set-top boxes, tablets and smartphones are equipped with digital video interfaces such as High Definition Multimedia Interface (HDMI) and Mobile High Definition Interface (MHL). Rohde & Schwarz's latest VTC video test system can be used to test the functionality of these interfaces and the associated protocol standards. R&S VTC supports real-time protocol testing and AV quality analysis with video difference comparison, making it the most flexible test platform on the market today.
The VTC video test system is an ideal test platform for R&D. It is functionally complementary to the existing R&S VTS compact video tester and R&S VTE video tester. R&S products already cover all testing needs in the consumer electronics production chain. VTC is a fully modular test platform designed to test video and audio interfaces and is a solution that integrates a wide range of test functions. VTC provides real-time protocol analysis and multimedia content analysis, and can arbitrarily modify test requirements and scenarios to meet complex R&D applications, depending on the specific test environment. The VTC's modular design allows it to be continuously upgraded to meet new standards, making it the most flexible test solution available today.
The VTC video test system can accommodate up to 8 test modules. Includes high-definition multimedia interface (HDMI) test modules, mobile high-definition interface (MHL) test modules, which are commonly used for consumer electronics testing. Modulator modules for analog audio/video interface modules and broadcast television standards will also be available soon.
VTC has real-time analysis function of video and audio parameters. Combined with HDMI test module, VTC can not only analyze HDMI signal source, but also test HDMI receiving device, support HDMI 1.4c protocol in R&SVTC, and realize protocol conformance test. For different interfaces, Rohde & Schwarz offers test software for automated testing. The VT-B2361 HDMI Receive Test Module has the ability to test Ultra High Definition (UD) resolutions of 4K x 2K resolution for high-end screens.
Rohde & Schwarz offers several options for automated analysis and testing of the video under test. These options can be used to test MHL and HDMI signals. The VT-K2100 Video Analysis Option tests the level and Timing of each part of the video signal to verify that the color transmission is correct. The VT-K2110 video inspection option and the VT-K2111 video distortion analysis option assist users with the analysis of the difference between the two images. While the graph displays the test results, the VTC also displays objective measurements such as PSNR, SSIM and MOS in real time. This feature allows you to pinpoint bit errors in your video content. VTC can even configure an audio analysis option to test audio levels, frequency response, phase response, signal-to-noise ratio, distortion and crosstalk.
The R&S VTC video test system is equipped with an 11-inch touch screen for easy operation. It can also be operated remotely via a LAN or PC or tablet. The VTC video test system supports multiple languages ​​including Chinese, Korean and Japanese. Its VXI-11 interface allows users to easily integrate VTC into an automated test system. VTC provides users with a future-proof, scalable platform that allows users to configure and upgrade VTCs to meet new standards and technologies based on their specific testing needs. The investment in VTC will never be outdated.
