In a one-to-many audio wireless transmission system in which a plurality of speaker devices on an audio reception side are provided with respect to one source device, in a case where an error has occurred in a certain speaker device, a possibility of the same error occurring in other speaker devices is reduced. A speaker device () includes an error detection unit () which detects an error regarding sound output and transmits error information which is information regarding an error detected by the error detection unit () to a source device () by using wireless communication. The source device () transmits an operation request corresponding to the error information by using wireless communication to speaker devices other than the speaker device which has transmitted the error information.

A peripheral control system enhances expandability in the operation of peripheral by enabling the customization and display of operation panels for each of the peripherals, regardless of whether any operation panel exists at the display device side. The peripheral control system is configured by connecting a TV and a recorder via an HDMI connection. The TV stores operation panel information that includes array information for arraying, on the screen, image data of the operation buttons that comprise the operation panel of the recorder. The recorder stores image data of the operation buttons, and sends, according to operation panel information obtained from the TV, the aforementioned stored image data of the operation buttons in association with the array information to the TV. The TV disposes and displays image data of the operation buttons sent from the recorder, at a position that is in accordance with the array information.

A broadcast receiver which can receive broadcast by directly selecting a discretionary broadcast station from all the receivable broadcast stations. The broadcast receiver is provided with a broadcast receiving section having broadcast station searching means for searching a carrier frequency of the receivable broadcast station. The receivable carrier frequencies searched by the broadcast station searching means are displayed as a list of broadcast station information on a display section, a specification from the list of broadcast station information displayed on the display section is accepted by operation of an operating section, and broadcast of the carrier frequency corresponding to the accepted specification is permitted to be received by the broadcast receiving section.

It comprises a head position-detecting device, a modeling data memory, a CPU, a coordinates transformation device, a compression transformation device, a polygon code memory, a polygon cache, an internally divided value generator, a rendering device, a display controller, a display and a restoration transformation device. The pixel of the image is selected roughly in the moving direction of the observer.

Three-dimensional image processing apparatus and three-dimensional image processing method

A media selecting device enabling a user to easily select any desired one of a plurality of selectable media. The media selecting device according to the present invention can easily select any one of a plurality of hierarchically-related icons by turning a rotary disk-type knob. The user presses a first change-over button to access the icon selected by the disk-type knob, and to display icons of a lower hierarchical layer or to display a deciding medium represented by icons. The user can press a second change-over button to cancel the selected icon, and to display icons of an upper hierarchical layer. Furthermore, the displayed icons have different three-dimensional shape and location information, and are disposed in a three-dimensional virtual space, thus increasing visibility and control of the device.

An image processing system, including a main CPU, a main storage, a three-dimensional image processor and a CRT for a display unit. The system further includes a system bus that connects the main CPU with the three-dimensional image processor to perform data transfer. In a preferred embodiment, the three-dimensional image processor also includes a command analyzer, a model data accumulating memory, a coordinate transformation processor, a viewing transforming circuit, a texture processing circuit and an image memory and video control circuit. The image processing system of the present invention makes it possible to reduce a load on the main CPU, which shortens data transfer time and thereby improves processing speed of the system.

A frame memory device for graphics includes a frame memory made up of a pair of memories and a memory controller for controlling the frame memory and is able to smoothly access the frame memory and is improved in its rendering speed. Each memory is logically divided into two banks A and B. Addresses in the thus divided bank are arranged in a checker pattern. The memory controller simultaneously selects bank addresses horizontally and vertically adjacent to a bank address currently being accessed.

A character code storage device stores character codes together with display permission information (display levels) attached to every character code. A font data storage device stores font data together with display level values attached to every dot constituting a font. A dot-display-value synthesizer synthesizes these two data and controls dot-display for representing a character according to two kinds of information--display permission information and display level values. The display permission information from a display-permission-value register is reflected at every display level value of dots constituting a font corresponding to the character. When each dot is read from a display circuit, its display level value is also read out and transferred to a display control unit. The transferred dot is compared with a display-permission-level value stored. Dot data which does not meet the condition will not be sent to the display circuit. Consequently, this dot is masked.
