US Patent 7664374 Digital convergent recorder

The invention generally relates to a digital convergent recorder. The digital convergent recorder may generate and record into a storage device (e.g. HDD) a first digital data in a first compress format (e.g. MPEG2) out of an external input analog AV signal or a digital broadcasting signal, may generate and transmit via internet to an external computer a second digital data in a second compress format (e.g. M-JPEG) out of the external input analog AV signal or an analog AV signal obtained by decoding the first data from the storage device, and may control the MPEG2 encoding/recording mode responding to a user command received through a specific command/control protocol from the external computer.
