Abstract:
A video card comprising:a memory means for recording video signals;a camera signal inputting means for converting video signals input from a camera device to an intended format and recording the same in said memory means;an encoding means for encoding said recorded input video signals and recording the encoded video signals in said memory means;a first transmitting means for transmitting said recorded encoded video signals to a host control device;a receiving means for receiving the encoded video signals transmitted by said host control device and recording the same in said memory means;a decoding means for decoding said recorded received encoded video signals and recording the decoded video signals in the memory means;a second transmitting means for transmitting said recorded decoded video signals to said host control device;a third transmitting means for transmitting said recorded input video signals to said host control device; anda controlling means for making predetermined means valid based on a control signal input from said host control device and making them carry out intended processings, whereinsaid encoding means and said decoding means are substantially constituted by one signal processing means,said first to third transmitting means and said receiving means are substantially constituted by one interface, andsaid means are contained in a card-like housing, and whereinreceiving operations are given priority over transmission operations when the amount of reception data remaining in said memory means is greater than the amount of transmission data remaining in said memory means.
