We used that mode, but re-interpreted the data. ![]() In more detail: Amiga had a frame buffer mode that displayed 736x483 pixels, but only 4-bits per pixel (16 colors). I will describe in more detail below, but it assumes some familiarity with NTSC composite video signals. I know that is pretty ambiguous, but it is a general description. ![]() We used a technique that encoded the data on two consecutive lines in the Amiga frame buffer in a way that we could reconstruct a composite video signal when run through some processing and combined with data from the previous line (delayed through a line memory). ![]() I didn't really remember! Luckily I still have all the lab books and design notes from those days filed away. The onscreen display was spectacular, but I could never figure out how it was working.Īfter some research, I found the hardware engineer that built the DCTV and we exchanged some messages where he explained the system. It would take the regular frame buffer output, displayed as is from the Amiga, in which you could kind of see the shape of the final picture, and turn it into a full color image. There is a YouTube video showing it in action. The pass-through connector would go on the video output port and the monitor cable would go on the other side, while the second connector would go on the parallel port. although DCTV does not interfere with normal genlock operation, its output cannot be fed into a genlock without the DCTV RGB Converter.DB23 RGB connector passthrough for connecting two monitors at the same time - one for the Amiga (RGB) and one for the DCTV (composite).the parallel port is used for sending digitized images to the Amiga.slow scan video digitizer - captures a still video frame in 6 to 10 seconds.Uses the Amiga RAM as framebuffer - requires at least 1 MB of memory for functioning in case of pictures with a lot of detail (like text) the display is blurry.for pictures that contain a lot of color changes (like photographic materials) the quality is as good as everyday television.The resulting composite image quality is far better and much worse than a normal Amiga RGB display: these screens contain the digitized and compressed form of the analogue waveform data required to create the composite display.the information is encoded into special Amiga display screens that DCTV recognises by a signature in the upper-left corner.Uses the RGB port as an I/O port for sending compressed video information: It was released in 1991 for $495 in the USA.ĭCTV - Digital Composite Television - turns digital data from the RGB port to composite television signal It is able to output a picture with full color video composite quality and also digitize a composite video signal. The DCTV is a hardware device from Digital Creations that connects to both the video port and the parallel port of an Amiga. I spoke with the hardware designer, and for the first time we can understand how it worked. This can include tasks such as image recognition, object detection, image generation, and image manipulation.This is an unusual question since I'll answer it right away because it was a truly unique device and there is absolutely nothing about the technology it used on the internet. AI image refers to an image that has been processed or generated by an artificial intelligence (AI) algorithm. At end the file from IMAGE to AI converteredĪI stands for artificial intelligence.File will be upladed and you can see loading icon.Select file from file selector or drag file in drag box.you just have to select which file should be converted we will convert it for you.we don't ask you to provide your email or for any registration process.This converter is free to use with more than 50 conversion tools beside it. ![]()
