摘要： The present invention relates to a transmitter and a receiver for speech coding and decoding by using an additional bit allocation method. The transmitter and the receiver according to the present invention realize a voice communication service of high quality by using additional bits permitted in system requirements while using a conventional speech coder as it is. In addition, the transmitter and the receiver according to the present invention have an advantage in that they enable insertion of additional quantization blocks while not changing the structure of the conventional standard speech coder, since they allocate additional bits by applying a multi-stage quantization procedure not in a speech signal domain but in a parameter domain.

摘要： A method and an apparatus for transmitting a speech signal are provided. A speech signal transmitter includes a quadrature mirror filter, a base sub-band encoder, an enhancement sub-band encoder, and a network connector. The quadrature mirror filter receives a speech signal, divides the speech signal into an enhancement band speech signal and a base band speech signal, and outputs the enhancement band speech signal and the base band speech signal. The base sub-band encoder receives and encodes the base band speech signal. The enhancement sub-band encoder receives and encodes the enhancement band speech signal. The network connector multiplexes the encoded enhancement band speech signal and the encoded base band speech signal based on the kinds of networks over which speech signals are transmitted, and transmits the multiplexed signals to the networks. A speech signal is multiplexed and transmitted by various methods based on the kinds of networks. Thus, the speech signal can be efficiently transmitted.

摘要： A home intelligent service robot for recognizing a user and following the motion of a user and a method thereof are provided. The home intelligent service robot includes a driver, a vision processor, and a robot controller. The driver moves an intelligent service robot according to an input moving instruction. The vision processor captures images through at least two or more cameras in response to a capturing instruction for following a target object, minimizes the information amount of the captured image, and discriminates objects in the image into the target object and obstacles. The robot controller provides the capturing instruction for following the target object in a direction of collecting instruction information to the vision processor when the instruction information is collected from outside, and controls the intelligent service robot to follow and move the target object while avoiding obstacles based on the discriminating information from the vision processor.

摘要： A network-based mobile robot is provided. The mobile robot includes a video encoder, a bit rate analysis unit, an inference unit, and a switch unit. The video encoder encodes an image with a variable bit rate to output bitstreams in a frame unit. The bit rate analysis unit analyzes a size of the bitstreams per frame from the video encoder. The inference unit infers a bitstream output start point and end point by comparing the size of the bitstreams to a predetermined reference value based on the analyzing result and determines whether an object in the bitstreams per frame moves or not. The switch unit selectively starts and ends the inputted image output operation to an internal image processing processor and the bitstream output operation to a remote server that is connected via a network and perform image processing, based on the inferring result of the inference unit.

摘要： A DMA controller includes a channel status generator determining whether the state of a channel connected to a peripheral corresponds to the first part of transmission data when receiving a DMA request from the peripheral; an address generator generating addresses of the peripheral and a memory; a control signal generator generating signals representing DMA operation states; and a buffer temporarily storing data from the peripheral and transmitting them to the memory. The address generator generates an address of a register storing a data transmission size of the peripheral when the channel state represents the first part of the data. The control signal generator generates a control signal for receiving a value stored in the register storing the data transmission size.
