摘要： A method and apparatus for encoding input digital data by high-efficiency encoding, a method for transmitting the encoded information and a method and apparatus for reproducing and decoding the transmitted information, are disclosed. For encoding, an input signal is forward orthogonal transformed into spectral signals using a windowing function for forward orthogonal transform having a shape A. For decoding, the spectral signals are inverse orthogonal transformed using a windowing function having a shape B different from the shape A. The degree of concentration of the energy of the spectral distribution may be raised and efficient encoding may be achieved even in case of modified DCT (MDCT) wherein the windowing function needs to satisfy a pre-set constraint.

摘要： A method for encoding audio signals includes dividing input audio signals into a two-dimensional block of time and frequency and quantizing the two-dimensional blocks based upon bit allocation as determined for each of the two-dimensional blocks. Scale factors are calculated indicating characteristics of signal components for each of the plural two-dimensional blocks, and bit allocations are determined for a pre-set one of the two-dimensional blocks based upon the scale factor of the pre-set two-dimensional block and plural scale factors of plural ones of the two-dimensional blocks neighboring to said pre-set two-dimensional block on the frequency axis.

摘要： A client terminal searches for servers on a home network when a song-data playback application is started up. When the client terminal receives a response from a server which was in connection therewith at the preceding operation, the client terminal establishes a preferential connection with the server and stops a process of searching for the servers. The client terminal obtains a list of album names and song data from the connected server so as to display the list, and plays back song data selected by a user by streaming.

摘要： To make it possible to provide high-quality music signal regardless of the advertising voice superimposing position, an encrypted pure music signal input through a transmission medium and an unencrypted advertising voice signal are separated by a signal string separation section. A signal transform and combining section decodes the encrypted pure music signal and combines the decoded music signal with the advertising voice signal into a resultant signal of the music and advertising voice signals, then outputs the resultant signal to a code string combining section, which then combines the encrypted pure music signal and the resultant signal of the music and advertising voice signals and supplies the result to a recording section for recording the result on a magneto-optic disc.

In the data encoding apparatus for encoding and subsequently variable length encoding the input data, spectral data obtained on orthogonal transform coding are routed to a block floating circuit 403 for normalization and re-quantized in a quantization circuit 404 depending on the bit allocation number information from a bit allocation calculating circuit 406 so as to be then variable length encoded by an encoding circuit 407 and outputted at an output terminal 408. The bit allocation circuit 406 refers to a table memory circuit 409 in which re-quantized data domain is divided at boundary points corresponding to code length transitions in order to calculate the total number of bits required for encoding using a smaller volume of arithmetic-logical operations for the purpose of adjusting the number of allocated bits.

摘要： To realize an information processing apparatus for editing data which enables editing of data intuitively with a simple operation. A track segment is displayed at a position corresponding to a track number on a first coordinate axis in a track segment display area, with a range corresponding to the period from the start time to the end time of the track on a second coordinate axis, so that it is possible to intuitively notify a user of the place in the order and the performance time of each track based on the position relationship among track segments and the length thereof. Furthermore, in response to an operation to move a track segment along the first coordinate axis, the track number of a track corresponding to the track segment is changed; the order of tracks is also changed; and in addition, the track segment is displayed as having moved to the position corresponding to the changed track number and the changed place in the order. Thereby, it is possible for the user to easily change the order of tracks with an intuitive operation.

A signal level that corresponds to one of the plurality of input channels and another signal level from another of the plurality of input channels are determined. A second audio signal is selected on the basis of the signal levels such that the second audio signal is selected from the group consisting of the one input channel, the other input channel, and a signal generated from the number of input channels that is different than the first audio signal. The first audio signal and the selected second audio signal are separately coded.
