Abstract

Methods and apparatus for processing data representing multiple image sequences, e.g., TV programs, and displaying multiple images from different video sequences in different windows of a single display screen are disclosed. The amount of system resources required to process and display the image data are a function of the size of the windows in which the images are displayed. In accordance with the present invention demand for system resources is assessed and compared to the amount of available system resources. If the demand for system resources will exceed the available system resources, the size of one or more of the windows used to display secondary images, e.g., the small PIP windows, is reduced to reduce the burden, e.g., processing or bus bandwidth burden, on one or more system resources. In one embodiment, the system suggests a set of window sizes to the user which will allow for the decoding and display of programs without exceeding the available system resources. The user can accept or modify the suggested program window sizes. When the user input results in the use of window sizes that will result in a demand for system resources that exceeds the available resources, da…
