高效智能的电视频道切换方法

Highly efficient intelligent television channel switching method

Abstract

本发明涉及一种高效智能的电视频道切换方法,该电视信号接收系统包括天线、调谐器、声表滤波器、中频处理芯片、基带视频处理芯片、显示控制芯片、微处理器、存储器、OSD发生器、显示屏、ADC转换器及电源处理模块连接组成;实施步骤如下:在系统第一次启动时分配非易失存储器空间以存放常看频道列表,分为两路:一路遇到用户普通换台操作,统计用户频道切换和每个频道观看时间,对常看频道列表进行排序操作,是否进行更新列表,是则更新列表并创建台标截图,否则切换到指定频道;另一路:遇到用户按常看频道键,显示常看频道列表,用户通过上下左右进行选择,然后进行更新列表并创建台标截图。其步骤简单易行,有效解决了电视机频道切换繁琐的难题。
The invention relates to an intelligent television channel switching method with high efficiency. A television signal reception system comprises an antenna, a tuner, a saw filter, a medium frequency processing chip, a base band video processing chip, a display control chip, a microprocessor, a memory, an OSD generator, a display screen, an ADC converter and a power supply processing module which are connected together. The implementation step is as follows: when the system is started for the first time, the space of a nonvolatile store is allocated so as to deposit a common watched channel list and is divided into two channels: one channel counts the time of switching channels of the user and the watching time of every channel when one channel meets a common switching operation of the user, ranks the common watched channel list; whether the list is updated or not is decided; if yes, the list is updated, and a station caption sectional drawing is established; if not, an appointed channel is switched to; the other channel displays the common watched channel list when the other channel meets a common watched channel key of the user; the user selects by top and bottom, right and left, and then updates the list and establishes a station caption sectional drawing. The step of the method is easy, thus effectively solving the difficult problem of switching television programs frequently.
