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.

For achieving a video display of high picture quality, a video signal processing method comprises the following steps of: a step for produce a sub-field light-ON pattern signal for controlling light-ON or -OFF at a pixel, during said plural number of sub-field periods, depending a pixel value of the pixel in the input video; and a signal correcting step for correcting said sub-field light-ON pattern signal, with using a motion vector obtained through a motion vector search, which is conducted on a first frame in said input video and a second frame, time-sequentially prior to said first frame, wherein said sub-field light-ON pattern signal has light-ON pattern signal for each pixel during each of the sub-field periods between said second frame and said first frame, and said signal correcting step determines the light-ON pattern information of one pixel during one sub-field period, with using a motion vector passing said one pixel within said sub-field among said motion vectors, while determining light-ON pattern information during said one sub-field of said one pixel when there is no motion vector passing through said one pixel, whereby producing a new sub-field light-ON pattern signal having the light-ON pattern information newly determined.

In a cellular phone terminal, a bit error rate measurement section measures a bit error rate of broadcast data received by a broadcast reception section for receiving a digital broadcast to output broadcast data while a transmission operation of a communication transmission section for wirelessly communicating with a broadcasting communication network is performed. When the measured bit error rate is equal to or higher than a predetermined threshold, stopping of the transmission operation of the communication transmission section is instructed. Thus, a failure such as interruption of television broadcasting reproduction can preliminarily be prevented by avoiding error occurrence in reception of the 1 segment broadcasting service due to an influence of a transmission electric wave in data communication. As a result, stable reception of the 1 segment broadcasting service can be executed.

A laser beam transmission apparatus comprises a light-incidence optical system (22) converging and focusing a laser beam emitted from a solid-state laser apparatus (1), and an optical fiber (8) which transmits the laser beam that has been converged and focused by the light-incidence optical system. The light-incidence optical system (22) has at least first and second lenses (13, 14) disposed on the same optical path. A first distance (a) between an output end of the solid-state laser apparatus and the first lens or a second distance (b) between the second lens and a light-incidence end of the optical fiber is freely set according to a relational formula based on a focal distance (f1, f2) of each of the first and second lenses.

A method of displaying program-related information while the user views a program video mainly and a broadcasting program displaying device to implement the method without making the user's operation complicated and confusing. A picture plane is constructed by two picture planes having a television picture plane (picture plane 1) for displaying the program video which is outputted from a broadcasting program displaying device and further a property state picture plane as another picture plane (picture plane 2). The program video is displayed to the picture plane 1 and an operation picture plane of the broadcasting program displaying device and the program related-information are displayed to the picture plane 2. A broadcasting program displaying device for two-screen construction has functions for display, recording, replay, reservation recording, and the like in response to an instruction from a device which the user operates.

Air" wherein Sub. is a transparent substrate; H and L are layers of high refractive index material and low refractive index material, respectively, stacked alternately to form multilayer dielectric coatings; (H.multidot.L).sub.4 stands for a series of four layer pairs each consisting of high refractive index material layer and low reflective index material layer stacked alternately H and L; Air stands for an atmosphere to which the top surface of the multilayer coating is exposed; each of H and L has a thickness of .lambda..sub.0 /4; .lambda..sub.0 is 6328 .ANG.; n.sub.1 is a natural number selected from the group consisting of 3, 5 and 7; and n.sub.2 is a natural number determined by n.sub.2 =9-n.sub.1. Likewise a preferred multilayer structure of the total reflection mirror is represented as "Sub. .vertline.(H.multidot.L).sub.11 .multidot.H.multidot.7L.vertline. Air". Use of these mirrors effects increase in reflectivity at .lambda..sub. 0 =6328 .ANG. and reduction in reflectivity at .lambda.=3.39 .mu.m to not more than 1%. Thus it can be achieved to increase power output at .lambda..sub.0 =6328 .ANG..
