A portable video adaptor for connecting between an AV signal source and a computer includes a fan for cooling the video processing chip. The mobile video adapter stick includes a housing 11, which has an interface 132 e.g. a USB or IDE connector for connection to a computer, air vents 133, a rear adapter interface 134 for connection to an audio and video signal source, a circuit board 2, a video processing chip 21 electrically connected to the USB interface 132 and the adapter interface 134 for processing inputted audio and video signals, and a cooling fan 3 for cooling the video processing chip. The cooling fan causes air to flow between air port 31 and vents 133 across the video processing chip 21, lowering the temperature inside the housing and hence increasing the life of the chip. |
