Processing of image data ∫ By data type Image data is processed by the AG-MX70 either as Title data or IntVideo data, depending on the application. When image data is transmitted to the AG-MX70, it is necessary to first select one of these 2 data types. ≥ Title data Data to be used for DSK playback should be transmitted as Title data. RGB data and α channel data are used by Title data. When an image having an α channel is used, the image is subjected to transparency processing corresponding to the value of the α channel. When an image not having an α channel is used, transparency processing is not performed. ≥ IntVideo data When the image is to be played back as internal matte, it is transmitted as IntVideo data. The image uses only RGB data. As the α channel is not used, transparency processing is not performed. ∫ Display methods It is possible to select from the following display methods according to how the image data is to be played back. ≥ STILL With this method, a single image is played back as a still image. Both Title data and IntVideo data can be used. When Title data is used, it is possible to set the horizontal position and vertical position of the image. ≥ MOVIE With this method, two or more images are played back consecutively. A single image is processed as one frame. It is possible to select from ONCE or REPEAT playback. Both Title data and IntVideo data can be used. When Title data is used, it is possible to set the horizontal position and vertical position of the image. 5 1 ≥ CRAWL Two or more images are lined up one after the other and played back (scrolled) horizontally on the screen. It is possible to set the direction and the speed for scrolling. Only Title data can be used with this method. It is possible to set the vertical position of the image. 5 1 5 1 ≥ ROLL Two or more images are lined up one after the other and played back (scrolled) vertically on the screen. It is possible to set the direction and the speed for scrolling. Only Title data can be used with this method. It is possible to set the horizontal position of the image. 5 5 1 1 ∫ DSK effects When an image is displayed on (DSK ON) or cleared from (DSK OFF) the monitor, it is possible to apply dissolve or 2 or 3D transition effects. ∫ Image size The appropriate size of images for the Monitor 1 screen differs, depending on the video format setting of the AGMX70 and the MX-Navi settings. NTSC: Monitor 1 screen = 640 a 480 PAL: Monitor 1 screen = 768 a 576 It is possible to select any image size for playback, however, if the image size selected is larger than the Monitor 1 screen, only the part of the image that fits onto the screen will be transmitted and played back. ∫ Image formats supported It is possible to use the following image formats for playback with the AG-MX70. ≥ TARGA (.tga) 24 bit/pixel (no α channel) data and 32 bit/pixel (with α channel) data can be used. ≥ JPEG (.jpg) ≥ BMP (.bmp) 24 bit/pixel (no α channel) data can be used. A 32 bit/pixel image of the TARGA format must be used when the image is to be displayed with transparency processing. When displaying images using either MOVIE, ROLL or CRAWL methods, it is necessary to use consecutively numbered file names. (e.g. Image001.tga to Image015.tga) 75
