根据HDMI协议，显示端（例如电视），在整个设备上电完成，没有异常，会向信号源端（例如蓝光DVD)发送一个准备ok，可以接收HDMI信号的引导信号，这个信号就是在HOT PLUG这个PIN上发送的。显示端先把HOT PLUG拉低，再拉高，信号源端接收到这个信号后，就和显示端进行握手协议类的通讯协议，如果无异常，信...
HDMI勉强(hot plug 视频数据处理流程)●Hot Plug Detect Signal(热插拔检测信号)理解 当E-EDID为读无效时,HDMI接收机(譬如:PJ)不应该断言有高电平在它的脚Hot Plug Detect上。只有当+5V电源线从源设备(发送机,譬如DVD)被检测到后,这Hot Plug Detect脚才断言。这将保证那些热插拔检测脚在第三方连接器厂家前没...
In my application I need to detect the HDMI display connected/disconnected and display resolution change. For example if the user replaced a 1080 display with a 720 I have to detect such change and rescale the output accordingly. These are the kernel messages when swapping the displays: imx-...

Moreover, if a period of the low level of the hot plug signal is shorter than Tout, a period of the low level is prolonged to Tout, which allows the transmission processing unit to surely detect the low level without shortening a cycle at which the hot plug signal is detected. 展开 ...
