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...

if there is off the shelf hardware (either a HDMI cable, DVI cable, DVI to HDMI cable, or an adapter of any of those types) that has the hot plug pin jumpered (or connected in such a way) that even if there is no monitor connected the PC will detect that a monitor is connected....
If the HPD is connected to a video display through an HDMI(High Definition Multimedia Interface), the HDMI generates the HPD signal in the operating voltage of the first modem. The hot plug detector provides the HPD signal to the first modem. If the HPD signal is detected, the first modem...
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 ...
Q2: This is not applicable to the TFP401 as it does not have a clock detect feature. Please see the "Sync Detect" section of the datasheet. Regards, I.K. Hi I.K.-san, About Q2: Is there any information about how long it takes from the input of clock and data (=hot plug) ...
