Abstract: A recording/reproducing method includes: reading a first uncompressed data from a first recording medium; reading the first uncompressed data from a buffer memory at a speed higher than a normal reproduction speed and compressing the read first uncompressed data to generate a compressed data; and recording the generated compressed data in a second recording medium; determining whether a predefined unit volume of compressed data is recorded in the second recording medium; and when it is determined that the predefined unit volume of compressed data is not yet recorded in the second recording medium, generating a second uncompressed data by reading the compressed data from the second recording medium at a speed higher than the normal reproduction speed and decompressing the read compressed data when it is determined that the predefined unit volume of compressed data is already recorded in the second recording medium.

Abstract: The present invention provides a CEC communications device which eliminates a troublesome process to solve the CEC-related communication malfunction when the CEC communications device detects a CEC-related communication malfunction caused by a software malfunction and improves serviceability of the CEC communications by automatically resetting the CEC to execute a CEC communication recovery. In the CEC communications device, when a CEC communications line monitoring unit detects a CEC-related communication malfunction caused by a software malfunction, a CEC control unit determines a reset order of a CEC appliance found on a CEC network, and notifies the CEC resetting unit of a CEC resetting request. The CEC resetting unit resets the CEC of a CEC appliance found on the CEC network via an HDMI line (DDC in FIG. 1) other than the CEC to recover the CEC communications.
