摘要： A video frame is input to a spectrum analyzer, which transforms the frame from a spatial domain into a frequency domain. A resolution determiner analyzes the output of the spectrum analyzer, thereby selecting a resolution appropriate for the video frame. Then, a resolution converter converts a resolution of the video frame into the resolution selected by the resolution determiner. Thereafter, the video frame is subjected to a coding process by block divider, DCT transformer, quantizer and variable-length coder so as to be output as a coded bit stream. By coding the input video frame at a resolution corresponding to the high-frequency component in the frame, a video of higher quality can be obtained with the bit rate reduced.

摘要： An encoding/recording device encodes a video signal according to MPEG, encodes an audio signal with a predetermined method, and multiplexes the encoded video signal and the audio signal to produce a system stream. The encoding/recording device then records the system stream onto a recording medium. On receiving a pause instruction, the encoding/recording device suspends reception of the audio signal and the video signal in synchronization with a timing with which the video signal is received, and thereafter suspends encoding, multiplexing, and recording for the audio signal and the video signal with predetermined timings. On receiving a pause release instruction, the encoding/recording device resumes reception of the audio signal and the video signal in synchronization with a timing with which the video signal is received, and thereafter resumes the encoding, the multiplexing, and the recording with predetermined timings. When suspending the encoding for the video signal, the encoding/recording device keeps information showing how an amount of video data accumulated in a buffer in a virtual decoder changes, and uses the kept information when resuming the encoding.

摘要： An apparatus for embedding information in a signal includes a band dividing device, a block divider, a quantization portion, a signal replacement portion, a mean difference addition portion, a mean calculation portion, and a band synthesis portion. The band dividing device divides the signal into transform coefficients over a plurality of frequency bands. The block divider divides one frequency band into a plurality of blocks in accordance with a previously determined block size. The quantization portion calculates for each block, a mean value M of the transform coefficients in the block, and subjects the mean value M to linear quantization, using a previously determined quantization step-size Q to calculate a quantization value. The signal replacement portion replaces the quantization value for each block, on the basis of the quantization value and the value of the information to be embedded. The mean difference addition portion subjects the replaced quantization value, for each block, to inverse linear quantization using the quantization step-size Q to calculate a mean value M′, and adds a difference DM between the mean value M′ and the mean value M to all the transform coefficients in the block. The mean calculation portion calculates a mean value LM of the transform coefficients in the frequency band after the addition of the difference DM. The band synthesis portion reconstructs a signal in which the information has been embedded using the frequency band after the addition of the difference DM and the other frequency bands.

摘要： An electronic device (e.g., a display device) (101) is connected with an external connection device (e.g., an image recording/playback device) (201), thereby to perform data communications. A controller (103) of the electronic device (101) decides, in case it receives operation information, whether or not an operation screen (GUI) for the electronic device (101) is displayed. When the operation screen is displayed, the controller (103) further decides whether or not a key (a reception key) corresponding to the received operation information is effective for the operation screen. The controller (103) performs, when the reception key is effective for the operation screen, a control responding to the reception key, and, when the reception key is not effective for the operation screen, sends the received operation information to the external connection device (201). With the operation screens of both the electronic device and the external connection device being simultaneously displayed, one remote control makes only one operative, while the operation screens of the two being prevented from simultaneously operating.
