    摘要： A radio line is easily influenced in its nature by attenuation or reflection of an electromagnetic wave or the like and the surrounding environment. Due to this fact, a variation of the data transfer speed frequently occurs at the time of image streaming so as to become a hindrance to reproduction of an image at the receiving terminal. A distribution server is provided with a multiplexer for multiplexing information indicating the transmission start time for the image data and a switching unit for switching an image bit rate in response to a request from the receiving terminal. The receiving terminal uses information indicating a transmission start time for the image data, monitors the receiving bit rate and sends out a request for transmission of the most-suitable image bit rate in response to a comparison thereof.

    摘要： A conventional coding method has a problem that for frame-by-frame reverse playback, data must be once decoded in a forward direction and thus a larger volume of data must be processed and a larger volume of memory is required.By recoding a forward predicted picture and a backward predicted picture for a frame in a bit stream, the bit stream can be played back reversely frame by frame easily. By the use of this method for multi-viewpoint video coding, a device that can play back pictures while varying the viewpoint in real time is realized.

    摘要翻译： 传统的编码方法存在的问题是，对于逐帧反向重放，数据必须在向前方向一次解码，因此必须处理更大量的数据，并且需要更大量的存储器。 通过重新编码比特流中的帧的前向预测图像和后向预测图像，可以容易地逐帧地反向地重放比特流。 通过使用这种多视点视频编码方法，实现了可以实时改变视点的同时播放图像的装置。

    摘要： When a non-error-resilient application decoder receives a data stream containing syntax error due to transmission errors, such as packet losses in wireless communication, an application decoder cannot usually continue decoding the stream data anymore. According to the present invention, the data stream containing syntax error along with error correction data generated by error-detectable transmission system is inputted into an error correction part before inputted into the application decoder. The error correction part detects the error position in the data stream using the error detection data, corrects the syntax error in the stream data, and generates a stream data which is possible to be decoded by the application decoder. As a result, the data stream containing syntax error can continue decoding or be decoded in better quality by a non-error-resilient application decoder, without adding any error correcting function in the existing application decoder.

    摘要： To facilitate positioning of a drill bit and alleviate burden to a user, a medical drill machine including a drive shaft gripping a drill bit, a casing constituted of X-ray transparent material and capable of housing the drive shaft, and a force transferring mechanism for transferring rotational force to the drive shaft is provided. In this medical drill machine, a first guide and a second guide constituted of X-ray opaque material are fixed at given positions along an axial direction of the drive shaft in the casing. Both guides are arranged coaxially with the axis of the drive shaft, and are formed in mutually different shapes. A slant direction of the drill bit can be recognized from any relative misalignment of the mutually different shapes of the guides included in an X-ray image along the ideal axial line.

    摘要： The conventional multimedia communication terminals require the implementation of a camera unit for video input and a video encoder for generating encoded video streams. This configuration is expensive and power-consuming, so that the life of battery for driving the transmitter will be short, or otherwise a battery of larger capacity will be required, resulting in a larger size terminal, with less portability. In accordance with the present invention, the video input and encoding process may be implemented in a video information generating apparatus separated apart from the transmitter. The video or audio and video bitstream generated by the video information generating apparatus will be retrieved by the transmitter, or stored once in a server and then forwarded to a receiver.
