Mobile terminal and method for controlling the same

A system and method for processing of audio and speech signals is disclosed, which provide compatibility over a range of communication devices operating at different sampling frequencies and/or bit rates. The analyzer of the system divides the input signal in different portions, at least one of which carries information sufficient to provide intelligible reconstruction of the input signal. The analyzer also encodes separate information about other portions of the signal in an embedded manner, so that a smooth transition can be achieved from low bit-rate to high bit-rate applications. Accordingly, communication devices operating at different sampling rates and/or bit-rates can extract corresponding information from the output bit stream of the analyzer. In the present invention embedded information generally relates to separate parameters of the input signal, or to additional resolution in the transmission of original signal parameters. Non-linear techniques for enhancing the overall performance of the system are also disclosed. Also disclosed is a novel method of improving the quantization of signal parameters. In a specific embodiment the input signal is processed in two or more modes dependent on the state of the signal in a frame. When the signal is determined to be in a transition state, the encoder provides phase information about N sinusoids, which the decoder end uses to improve the quality of the output signal at low bit rates.

Scalable and embedded codec for speech and audio signals

A hybrid digital/analog video recorder prevents both analog and digital copying. The recorder (including a digital tape deck) inputs and outputs both analog and digital video signals. At the analog input, a detector detects conventional copy protection in the analog input video, and in response disables recording thereof. At the digital input, a first detector detects anti-copy bits present in the input material and in response prevents recording. A second bit detector detects serial copy prevention scheme bits, and in response adds an anti-copy bit to the input digital stream, preventing later copying of such material. When another bit detector detects anti-copy bits present in the playback digital data stream prior to conversion to analog, an analog copy protection signal modifies the output analog signal, inhibiting copying of the output signal. In another version, a specially adapted video recorder or playback device copy protects video source material which for technical reasons is not copy protectable. A copy protect 'flag' is provided in a predetermined location in the video signal to be protected. The video recorder or playback device, upon detection of the flag at playback, modifies the output standard (NTSC) video signal with a conventional copy protection process.

A system for configuring a second biomedical device in the same configuration as a first device. The first device is configured as desired and then is connected through a communication link to the second device to be configured. A teach mode is invoked in the first device and a learn mode invoked in the second device. The first device receives identification data from the second device, such as the model number and software revision number. If acceptable, the first device compares individual parameters against default values. The first device then sends only those parameters which differ from the default values. The second device will then load these parameters plus the default value of the other parameters. Both devices will indicate a successful transfer of data by means of a display. If the identification data do not match, the first device will provide a prompt and no configuration data will be sent to the second device. The devices will issue a prompt if after a configuration session has occurred, the operator attempts to switch off the power to the device to exit the configuration mode or attempts to enter the teach mode without first assigning a new configuration name. Each device includes a continuously powered display for continually displaying that assigned multi-character name, even during conditions of power-off.

A wide band audio signal encoding apparatus, a wide band audio signal decoding apparatus, a wide band audio signal encoding and decoding apparatus and a wide band audio signal recording medium, each having a low bit rate, a wide band, a low distortion factor and a wide dynamic range are provided. Wide band audio data is divided into signal data of a predetermined natural number N of sub-bands, and the number of bits for quantization for sub-sampling is determined based on noise floor information of the above wide band audio data. The signal data of the N sub-bands are sub-sampled by the respective numbers of bits for quantization, and encoded data obtained by multiplexing the signal data of the sub-sampled N sub-bands are recorded on a wide band audio signal recording medium. Therefore, both he characteristics of an extremely wide dynamic range and a wide band can be concurrently achieved at a relatively low bit rate per channel. This arrangement allows the achievement of recording and reproduction of an extremely transparent natural sound extending to an ultrahigh frequency region, and a recording medium for recording a signal of the above wide band audio data and a reproduction sound field.

A low-pass filter (1) of over-sampling type over-samples an input digital audio signal T1 and filters and removes the low frequency components of the produced aliasing noise. A spectrum analysis circuit (3) calculates the spectrum strength of a predetermined band of the output signal from the low-pass filter (1). An expansion signal generating circuit (5) generates an expansion signal having higher frequency components from the output signal from the low-pass filter (1). A level control circuit (4) controls the level of the expansion signal according to the output signal from the spectrum analysis circuit (3). An adder (2) adds the level-controlled expansion signal to the output signal from the low-pass filter (1) thereby to generate a digital audio signal T2.

A video signal and an audio signal are transmitted from a source device to a sink device in conformity with respective predetermined interfaces through respective transmission channels. The respective interfaces include bidirectional interface such as an HDMI and an IEEE1394. A controller acquires delay information (TLv) representing the total delay time of the devices connected to the transmission channels conforming to the bidirectional interface and corrects the difference in reproduction time between the video and audio signals by using the acquired delay information (TLv).

A minimum residual is extracted from prediction loop outputs from blocks of predetermined periods to eliminate block common runs. Data which are shifted up are subjected to Huffman conversion to compress a 96 kHz, 24 bit, 6ch (13.824 Mbps) source at a compressibility of 0.7 so that the transfer rate will not exceed 9.6 Mbps prescribed by the DVD format. Similarly modes such as a 192 kHz, 24 bit, 2ch mode are realized. Thus, a huge amount of information on linear PCM super audio is compressed and can be recorded/reproduced in the DVD format, thereby prolonging the recording time.

PROBLEM TO BE SOLVED: To prevent the occurrence of an end omission and a start omission at a receiver side in IEEE 1394 transmission when the kind of transmission stream is changed. SOLUTION: When the kind of a stream is changed, an audio transmitter (a DVD player) 101 outputs a packet including a silence identifier and identifier information before the change for a prescribed time. Then, a packet which includes the silence identifier and the identifier information after the change is outputted for a prescribed time and it is transitioned to the stream after the change. Moreover, for the case of a silence identifier, an audio receiver (an amplifier) 102 immediately makes its output to approximately zero mute when the identifier before a transition is a non-encoding mode. When the identifier prior to the transition is an encoding mode, the output is made approximately zero mute after the completion of the process of the data being processed by a data decoding means 111 and it is transitioned to setting for data output in accordance with identifier information that accompanies a silence identifier while it is being muted by the silence identifier.
