摘要： The invention relates in general to a television receiver that is capable of displaying two video programs and an electronic program guide (“EPG”) simultaneously. The EPG is displayed in a first portion of a split screen containing a picture-in-picture (PIP) display. Scanning of the electronic program guide causes different video programs to be displayed in the PIP display while the user is still able to watch the original video program on a second split screen.

摘要： Provided is an image synthesizing device with which a specific display region P of a sub-image is synthesized and displayed within a specific display region Q of a main image displayed on a display 9, wherein this image synthesizing device comprises a frame memory with which the data in the synthesis and display region P out of the sub-image data is continuously stored in the order of input, after which the stored sub-image data is read out when the scanning address of the main image data is an address corresponding to the display region Q, and a selector 4 with which the main image data displayed on the display 9 and the sub-image data continuously and sequentially read out from the frame memory are inputted, and when the scanning address of the main image data is an address corresponding to the display region Q, the selected channel is switched from main image data to the sub-image data and outputted to the display 9 where this sub-image data is displayed, which allows the capacity of the frame memory used for image synthesis to be smaller, and allows the sub-image to be reduced or magnified at the desired scale factor.

摘要： An apparatus for driving a display panel comprises a receiving circuit of a TV broadcasting wave. The writing and reading operations of the pixel data to/from the memory are performed synchronously with the self-advancing clock signal, thereby preventing a disturbance of a display image upon channel switching. The display driving apparatus according to another aspect of the invention has two frame memories to alternately store pixel data and a memory control apparatus to control the writing and reading operations to/from the frame memories which makes a scanning line interpolation processing apparatus constructed by a memory, an arithmetic operating circuit, and the like unnecessary. Furthermore, the driving apparatus can be altered to allocate storage in a memory for pixels which are to be displayed in one picture plane. This storage allocation allows a motion image and the still image to be simultaneously displayed.

摘要： 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, data corresponding to inter-coded frames is ignored and/or decoding and display of secondary images is limited to images with significant scene changes.

摘要： The invention relates to the insetting of a moving picture in a moving main picture when the picture signals are in an encoded digital format. The main idea is that the picture signals are combined prior to decoding. The frames of the picture to be inset are scaled down by reducing the number of macro blocks in them in such a manner that the picture whole is retained. The macro blocks of a certain area of the main picture are replaced by the macro blocks of the reduced picture and the combined video signal is decoded. The video signals (ES1, ES2) to be combined may be picked up from different sources or extracted from a transport stream where they are in packets. The system according to the invention requires only a single decoder (210), which considerably reduces the amount of computation required by the combination of the pictures. The advantage is emphasized if there are several pictures to be combined.
摘要翻译：本发明涉及当图像信号处于编码数字格式时在移动主图像中的运动图像的插值。主要思想是在解码之前组合图像信号。通过以保持图像整体的方式减少其中的宏块的数量来缩小要插入的图像的帧。主图像的特定区域的宏块被缩小图像的宏块代替，并且组合的视频信号被解码。要组合的视频信号（ES1，ES2）可以从不同的源拾取或者从它们处于分组的传输流中提取。根据本发明的系统仅需要单个解码器（210），这显着地减少了图像组合所需的计算量。如果有几张图片要组合，则会强调优点。

摘要： In a television receiver having Picture-In-Picture (PIP), a controller analyzes the content of a video signal forming a main picture, and automatically adjusts the size and position of a PIP image to correspond to regions of the main picture exhibiting the least amount of motion, texture, and/or a repeating texture. The controller also prevents the PIP image from being positioned over text or faces or other important objects in the main picture.

摘要： A digital broadcasting receiver for realizing a picture-in-picture (PIP) screen using a plurality of decoders is provided. The digital broadcasting receiver includes a first decoder 30 and a second decoder 80 for decoding each of a plurality of broadcasting signals, and outputs two broadcasting signals on a PIP screen. That is, each of the broadcasting signals which are input simultaneously is decoded in the first decoder 30 and the second decoder 80, and the decoded image signals are output on the PIP screen. Thus, the digital broadcasting receiver provides an effect of performing a PIP screen function in which a plurality of decoders decode each of the broadcasting signals.

摘要： A television screen (24) is displayed as a window (25) within a larger displayed image (21), also referred to as a “picture-in-picture.” A control program associated with the window (25) provides additional functions to the window, including the ability to view the time, title, and other information about future programs, in the window (25). A user can switch between various preset lists of channels, and can dynamically edit such lists to add or delete channels. The control program senses the location of a cursor (37) relative to the window (25) and a control region, as defined therein. Depending upon the location of the cursor (37), the window (25) is either in a reduced-size state with fewer controls visible, or in an expanded-size state with greater controls visible.
