    &lt;/div&gt;无信号标记&lt;br /&gt;&lt;br /&gt;电视台结束了放送，开始播放多种颜色的测试图（如 SMPTE 彩条信号），能被用户看到。所以直觉上，测试图表示没有信号。&lt;br /&gt;&lt;br /&gt;可能会有一些文艺作品，吸收了这种「无信号」含义。然后将真的「无信号」的提示会与测试图一同出现。即使这不符合事实。&lt;br /&gt;&lt;br /&gt;准确的说，测试图表示电视台发送了空白内容，而这是有信号。真正的无信号，在模拟信号中是雪花，在数字信号中是蓝屏。（显示器没有信号，呈现雪花或者蓝屏的原因，应该也比较有趣。）&lt;br /&gt;&lt;br /&gt;相关微型博客：&lt;a href=&quot;https://t.me/gledos_microblogging/894&quot; target=&quot;_blank&quot; rel=&quot;noopener&quot; title=&quot;既是无，也是有 —— 标准测试项目&quot;&gt;既是无，也是有 —— 标准测试项目&lt;/a&gt;。&lt;br /&gt;&lt;br /&gt;&lt;a href=&quot;/search/result?q=%23%E5%8E%9F%E7%90%86&quot; title=&quot;#原理&quot;&gt;#原理&lt;/a&gt;</content:encoded></item></channel></rss>
