摘要： Successively transmitted images are stored in frame memories the contents of which are displayed. The user can freeze a desired image in order to view it for a prolonged period of time. When the image thus frozen is released from the freeze mode, the content of the frame memory storing it continues to be displayed until anew image is stored in this frame memory. When a new image has been written in the frame memory and a stage is reached in which the image is to be displayed, display-setting information pertaining to this image is read out and the image is displayed in accordance with this information. In a case where the display-setting information indicates that the image is to be displayed in combination with a designated image transmitted earlier and it is determined that the storage destination of the designated image had previously been placed in the freeze mode, this means that an unrelated image is presently being stored at this storage location. Accordingly, the image at this location is not displayed in combination with the first-mentioned image, and therefore only the first-mentioned image is displayed.
摘要翻译：连续发送的图像被存储在其内容被显示的帧存储器中。用户可以冻结所需的图像以便长时间观看。当如此冻结的图像从冻结模式被释放时，存储它的帧存储器的内容继续显示，直到新的图像被存储在该帧存储器中。当新的图像被写入帧存储器并且到达要显示图像的阶段时，读出与该图像相关的显示设置信息，并根据该信息显示图像。在显示设定信息指示要与先前发送的指定图像一起显示图像并且确定指定图像的存储目的地先前已经被置于冻结模式的情况下，这意味着当前正在存储该存储位置的无关图像。因此，该位置的图像不与前述图像组合显示，因此仅显示第一次提到的图像。

摘要： An information recording apparatus records data, which is in the format of packets received by broadcast, on a recording medium having a write/read capability. If the received data contains any unnecessary items of data that can be reproduced later, these items of data are eliminated at the time of recording on the recording medium. At playback, the eliminated items of data are restored and appended to the data read in from the recording medium. The resulting data, which is substantially the same as that in the packets received by broadcast, is outputted to a playback apparatus capable of reproducing the broadcast.

摘要： Image data is stored in a plurality of image memories each capable of storing at least one picture of image information, and the plurality of image memories are successively read and their stored images displayed. Ordinarily, the received image data is stored in whichever of the image memories has been designated by a memory number information contained in control data provided along with the received image data. However, when the memory number designated by the control data and the memory number information of an image memory whose stored data is currently being read out and displayed coincide, the writing of the image data in the image memory information whose number has been designated is prohibited. Instead, the image data is written in an image memory whose memory number differs from that of an image memory from which the data is currently being read.
