V2Analog takes incoming SDI signals and converts to YPbPr (SMPTE, EBU-N10), Betacam, or RGB component outputs or NTSC/PAL or Y/C (S-Video) composite outputs for complete integration into any workflow. V2Analog performs high-quality SDI digital to component or composite analog conversion at either SD or HD resolutions using AJA’s industry-leading conversion technology to ensure the highest quality images for the most demanding situations. Only digital to analog signal conversion is supported. Note: V2Analog does NOT up-convert or down-convert between SD and HD resolutions. Configuration can be set by on unit DIP switches or remotely via AJA MiniConfig software control over USB.
V2Analog performs high-quality SDI digital to component or composite analog conversion at either SD or HD resolutions with a full 10-bit data path. If a digital video camera is available for use, then a DV media converter or fire wire card is more advantageous because it enables full operation of the digital video camera.V2Analog is a high-quality, cost-effective digital to analog video converter that’s an ideal solution for integrating analog equipment such as monitors and tape decks into digital workflows. When performing simple analog-to-digital video conversion, a video capture card is equal in quality and costs less than a digital video (DV) media converter or fire wire card. 31) or grayscale reproduction using the 2 methods of analog-to-digital conversion. There was no significant difference in overall video quality (P =. An objective test was performed by videotaping a gray-scale test pattern off a computer monitor, digitally converting it by the 2 methods, and comparing the gray-scale values to the original pattern. Randomized side by side video comparisons were analyzed and rated by subjective quality. A subjective test was performed in which 12 archived analog videotapes, consisting of magnetic resonance angiograms, ultrasounds, neurosurgeries, and telemedicine applications, were converted digitally using the 2 methods. A procedure for final digital video production was created that used equivalent compression, pixel resolution, frame rate, and data rate for both systems.
A video workstation was devised containing 2 analog-to-digital video conversion systems: a digital video media converter with fire wire card and a video capture card. The purpose of this study was to compare 2 methods of analog-to-digital video conversion in anticipation of improving, refining, and standardizing digital video production for medical education, diagnosis support, and telemedicine.
