Abstract
A video card capable of being mounted in an information processing apparatus so as to enable suitable performance of a television conference system etc., wherein video data fetched into a video card from a camera by a capture operation is recorded in the first region of a DRAM and encoded at a signal processing unit. The encoded video data is recorded in the second region of the DRAM, sequentially transferred to a main memory of a notebook type PC, and transmitted to a network via a communication I/F card. The video data received from the network is stored once in the main memory, transferred to the fourth region of the DRAM of the video card, decoded at the signal processing unit, and recorded in the third region of the DRAM. Immediately before the next capture operation, the video data which was fetched into the first region of the DRAM before this and the received video data which has been recorded in the third region are displayed on a display via a VGA controller.
