Abstract: When a sub-image (A) and a sub-image (B) are displayed as semi-moving pictures on a multi-screen, the fields of the input sub-images (A) and (B) are determined. By setting the field determination result as one condition for a write to the memory 114, the sub-images (A) and (B) can be stably written to the memory 114 in either odd fields (ODD) or even fields (EVEN), and can be read and displayed on the screen without flickering characters due to line flicker. Furthermore, when video signals are switched for a channel switch or an input switch, the operation remote controller 501 can issue a switch instruction so that a write to the video memory 509 is stopped according to the generated switch signal, and the image is displayed as a still image. In response to a new input video signal, the number of write increase lines or picture elements for a write to the video memory 509 is set to n. The writing operation is performed m times (m is a natural number) for every other field.

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.

Abstract: The present invention utilizes a graphics layout language that is defined by the broadcaster or the studio to control the layout of graphic overlays in relation to corresponding images presented on a display. Each user interface component is divided into objects that define their individual behaviors and presentations. Data files using the hypertext markup language, HTML, layout these objects on the screen. By varying the HTML data files, control is provided to the broadcaster over what objects are displayed on the screen, where they are placed on the screen, and to a limited effect, their behavior. This can be accomplished without re-writing the executables as would be necessary in other television type user interface implementations.

Abstract: There occurs an output timing lag between audio and video, for example, in case of building a system. Excessive frame skipping, etc. occurs. Prior to comparing a PTS and an SCR of MPEG within an apparatus, an offset value is added to the value of PTS. A minus offset value is used for a fast decode process. Offset values are written into an audio offset value register etc. by a host CPU. A value obtained by adding PTS and an offset value and an internal clock SSC depending on an SCR are compared by an adder-subtracter. If comparison shows the decode process is still fast, a decision controller instructs, for example, display of the same frame twice.

In the case of a higher degree of the filter, a number of filter stages are cascaded (connected in series). Where a higher degree of decimation is required, feedback is provided in each filter stage.

Abstract: An implementation efficient video decoder suitable for use as a picture in picture decoder is described. In one embodiment, the video decoder receives primary and secondary bitstreams with the secondary bitstream including the video data intended to be displayed as inset pictures.
