摘要: An address generating and mapping device of a video capture system includes: a microprocessor having a counter counted by being synchronized with a horizontal synchronizing signal of a video signal, an address port for outputting an address to be used when reading from a memory, and a counter port for outputting the counter value and a bank selection signal by using predetermined higher bits among the counter output as the bank selection signal for selecting data banks of the memory; a counter for performing a predetermined operation according to a signal for selecting a mode, when a mode for generating an address necessary for storing the video signal is referred to as an address generating mode and a mode for mapping an address necessary for accessing the memory is referred to as an address mapping mode; multiplexers for outputting a counter value from the microprocessor to higher addresses of the memory when the mode selection signal is the address generating mode and outputting the addresses output from the microprocessor as higher addresses of the memory when the mode selection signal is the address mapping mode, and a bank selecting unit for outputting higher bits among the signals output from the counter built in the microprocessor as a signal for selecting the data banks of the memory when the mode selection signal is the address mapping mode. In the address generating mode, the counter counts the number corresponding to that of pixels constituting a horizontal line of the video signal to output as lower addresses of the memory and is cleared by a clear signal having the same frequency as that of the horizontal synchronizing signal of the video signal, and, in the address mapping mode, the counter connects address lines output from the microprocessor to lower address lines of the memory. The use of the mode selection signal can provide a simple address generating and mapping circuit for the video capture system.

摘要: A method for turning pages of a multi-purpose learning system comprising a picture book package in a form of a cassette having a memory, a main body having a number of controllers for reading data stored in said memory, an audio/video output unit having a monitor and a speaker for outputting audio and video signals processed by said controllers. The method includes the steps of setting circuits of the main body to a standby mode, displaying a starting display having page icons which can be selected by an user to turn pages to proceed in interacting with the multi-purpose learning system, determining whether one of said page icons displayed on the starting display is selected by the user, and outputting the corresponding server display data of the selected page to the audio/video output unit for a visual display. Since the page icons can be displayed in the starting display on the monitor to be selected by the user, a more simplified multi-purpose system possible to have a virtually unlimited maximum number of pages can be provided.
