摘要： A transmitting apparatus, a transmitting method, a receiving apparatus, a receiving method, a transceiver, a communication apparatus and method, a recording medium, and a program in which high quality voice can be decoded. A cellular telephone outputs coded voice data and also supplies uncoded voice sample data to a switching center while a telephone call is not made. Based on voice data used for the previous calculation processing and newly input voice data, the switching center performs calculation processing for quality-improving data for improving the quality of voice to be output from a cellular telephone that receives the coded voice data. The switching center stores the optimal quality-improving data as a user information database in association with the cellular telephone. The cellular telephone decodes the coded voice data based on the optimal quality-improving data supplied from the switching center.

摘要： The present invention relates to a data processing apparatus capable of obtaining high-quality sound data. A tap generation section 121 generates a prediction tap used for a process in a prediction section 125 by extracting decoded speech data in a predetermined positional relationship with subject data of interest within the decoded speech data such that coded data is decoded by a CELP method and by extracting an I code located in a subframe according to a position of the subject data in the subject subframe. Similarly to the tap generation section 122, a tap generation section 122 generates a class tap used for a process in a classification section 123. The classification section 123 performs classification on the basis of the class tap, and a coefficient memory 124 outputs a tap coefficient corresponding to the classification result. The prediction section 125 performs a linear prediction computation by using the prediction tap and the tap coefficient and outputs high-quality decoded speech data. The present invention can be applied to mobile phones for transmitting and receiving speech.

摘要： An image processing apparatus for processing first image data into second image data having a higher quality includes the following elements. A determination unit determines whether broadcast image data is up-converted image data generated by up-converting different image data by increasing the number of pixels forming the different image data. A down-converter down-converts the broadcast image data into down-converted image data by decreasing the number of pixels forming the broadcast image data. A first image converter converts, if the broadcast image data is not the up-converted image data, the first image data into the second image data by using the down-converted image data and the broadcast image data as the first image data. A second image converter converts, if the broadcast image data is the up-converted image data, the first image data into the second image data by using the down-converted image data as the first image data.

摘要： An image signal converting apparatus for converting a first image signal into a second image signal, where the first and second image signals include a plurality of pictures of different frames. A motion detector is operable to detect motion of the first image signal between a first frame and a second frame, and processing circuitry produces the second image signal based on an assumption of a pixel at a position corresponding to the detected motion. The apparatus may be employed to produce an output signal of either the same resolution as the first image signal with aliasing distortion reduced or eliminated, or with higher resolution in vertical and/or horizontal directions.

摘要： The present invention relates to an apparatus for processing an image signal etc. that are well applicable to removal of coding noise from, for example, an image signal. Based on five consecutive frames of an image signal Va, a memory portion 121 outputs as pixel data xi of predictive taps plural items of pixel data located in a space directional and time directional peripheries with respect to a target position in an image signal Vb. In the case, frames before and after a current frame are subjected to motion compensation by using a motion vector. A class classification portion 124 obtains a class code CL indicating a class to which pixel data of the target position in the image signal Vb belongs, by using the pixel data xi and motion vectors BWV(0), BWV(−1), FWV(0), and FWV(+1). A calculating circuit 126 obtains pixel data y of the target position in the image signal Vb based on an estimation equation by using the pixel data xi and coefficient data Wi that corresponds to the class code CL.

摘要： The present invention relates to a signal processing system, a signal processing apparatus and method, a recording medium, and a program in which high frequency components of a narrow-range signal having suppressed high frequency components can be restored with high accuracy. A narrow-range audio signal having low frequency components is divided into frames by a frame-unit dividing unit 11, and is spectral-transformed into a signal on a frequency domain by a DCT transform unit 12. A learning-produced-data table 14 extracts, at an address corresponding to a class code supplied from a classifying unit 13, high-frequency-component DCT spectrum data. In a spectrum combining unit 16, the extracted high-frequency-component DCT spectrum data is combined with low-frequency-component DCT spectrum data output from the DCT transform unit 12. Subsequently, a broad-range audio signal having combined high frequency components and low frequency components is output. The present invention can be applied to cellular phones.
