Abstract
A camcorder includes an input interface via which audiovisual information is received at a first rate measured in frames per second, n. A media processor coupled via a bus to the input interface receives the audiovisual information at the rate n, and transfers it to a capture buffer coupled via the bus at a second rate measured in frames per second, x, for storage. An output interface coupled via the bus to the media processor transmits the audiovisual information at a third rate measured in frames per second, y, wherein x plus y is less than or equal to n. A set of computing instructions executed on the general purpose processor in the camcorder program the media processor to transfer the audiovisual information to the capture buffer at the rate x and to transmit the audiovisual information at the rate y to the output interface.
