รายละเอียดเพิ่มเติม

The Visual Information Institute 2501B Video Test Pattern Generator is an essential tool used in video production, broadcasting, and quality control environments for generating standardized video test patterns. Here are the specifications and features of this video test pattern generator:

• Video Test Patterns: Generates a wide range of video test patterns including color bars, grayscale, crosshatch, multiburst, ramp, and motion patterns, facilitating the assessment of video signal quality, color accuracy, resolution, and geometry.
• Output Formats: Supports multiple video output formats such as SD (Standard Definition), HD (High Definition), and 4K (Ultra High Definition), with various frame rates and aspect ratios to ensure compatibility with diverse video equipment and display devices.
• Color Accuracy: Provides precise color reproduction with SMPTE (Society of Motion Picture and Television Engineers) standard color bars and other color reference patterns, enabling users to calibrate color accuracy, hue, saturation, and luminance levels.
• Resolution Testing: Includes test patterns for evaluating resolution, sharpness, linearity, and aliasing artifacts, allowing users to verify the performance of video displays, cameras, scalers, and image processing systems.
• Signal Integrity: Generates test signals for assessing signal integrity, synchronization, timing, phase, and jitter, aiding in the identification and troubleshooting of issues related to video signal quality, stability, and compatibility.
• Audio Testing: Some models may feature audio test signals such as tone generators, pink noise, white noise, and audio level meters for testing audio performance, channel balance, frequency response, and distortion.
• User Interface: Equipped with an intuitive user interface comprising menu-driven controls, on-screen display (OSD), and remote control options for easy navigation, pattern selection, and adjustment of settings.
• Modularity and Expansion: Offers modularity through optional modules or software upgrades for adding additional test patterns, formats, and functionalities, allowing users to customize the generator according to specific testing requirements.
• Portable Design: Compact and portable design with durable construction, suitable for field testing, on-site calibration, studio setups, and mobile video production units.
• Compliance: Adheres to industry standards such as SMPTE, ITU-R BT.709 (Rec. 709), ITU-R BT.2020 (Rec. 2020), EBU (European Broadcasting Union) standards, and other video signal specifications, ensuring accuracy and consistency in video testing and calibration procedures.
• Application: Ideal for use in broadcast facilities, production studios, post-production facilities, AV testing labs, educational institutions, and video equipment manufacturing facilities to ensure quality assurance, calibration, and troubleshooting of video systems.

The Visual Information Institute 2501B Video Test Pattern Generator offers comprehensive video testing capabilities, facilitating accurate assessment, calibration, and optimization of video equipment and systems for optimal performance and image quality.
