Television receiver able to display secondary channel information

具有第二画面显示能力(与PIP或POP)的电视系统包括两个信号处理电路(140，144，150；126，136，143，145，144，150)和接收舆的频道引导的电路(142)。响应于"BROWSE"命令，控制器(180)保持第一频道做为主画面(300b)的源，显示第二频道电视节目的文本(305b)，激励第二画面显示电路显示该电视节目。使用者可以同时看到第二频道电视节目的文本说明和电视节目，而不用改变提供主画的第一频道。 A television system having secondary picture display capability (such as PIP or POP) includes two signal processing arrangements (140,144,150; 126,136,143,145,144,150) and circuitry (142) for receiving a transmitted channel guide. In response to a "BROWSE" command, a controller (180) maintains the first channel as the source for the main picture (300b), displays text (305b) related to a television show on a second channel and activates the secondary picture display circuitry to display the television show. In this way, the viewer can simultaneously get the benefit of both a text description of the television show on the second channel and view a secondary image of the television show on the second channel, without changing the first channel supplying the main picture.
