Abstract: A diffraction element, an optical pickup and an optical disc apparatus are provided to improve optical property of small aberration and to reduce the aberration of the diffraction element by forming a second diffraction element without distortion. A diffraction element, an optical pickup and an optical disc apparatus comprise a first member, a second member and a third member. The first member is made of a transparent injection molded material, and has two optical surfaces. The second member is installed at one optical surface of the first member to form a first diffraction pattern on the surface and a first ultraviolet curable resin(100A) having a refraction index in a range of ±0.013 for the refraction index of the first member. The third member is mounted on the other optical surface of the first member to form a second diffraction element on the surface and a second ultraviolet curable resin(100B) having the refraction index in the range of ±0.013 for the refraction index of the first member.

Abstract: A picture display system having two display devices and a base device for supplying picture signals to one of the display devices and capable of having bidirectional communication with the other display device is disclosed. The picture display system (1) is made up by a mobile display device (100), a base device (200) and a large format display device (300). The base device (200) sends picture signals to the display device (100) and to the large format display device (300). On a display image surface of the mobile display device (100), there is provided a touch panel for detecting the contact position contacted by a user for displaying a remote-control panel RP accepting an operating input from the user on the display image surface. An operating signal conforming to a display item of the remote-control panel RP, displayed at a contact position, detected by the touch panel, is generated and transmitted by wireless communication to the base device (200). This base device (200) selects the picture signals, supplied from the external inputting devices (400), as a supply source of picture signals, responsive to an operating signal, to transmit the so selected picture signals to the large format display device (300).

Abstract: There is provided a video display system in which when supplying a video signal from a base station (200) to a plurality of display units (transportable one 100 and large-screen one 300), an operation instruction generator generates a screen select instruction corresponding to the direction of the user's touch on a touch panel (121) provided on the display screen of the transportable display unit (100) that displays an image corresponding to a video signal supplied from the base station (200) and transmits the operation instruction from the transportable display unit (100) to the base station (200), and a controller included in the base station (200) controls the channel selecting operation of two turning means included in the base station (200) correspondingly to the supplied operation instruction. Stroking the surface of the touch panel (121) on the display screen of the transportable display unit (100), the user can transfer an image between the plurality of display units (100, 300). Thus, the user can intuitively select an operation of the video display system in a manner different from that using a button on the conventional remote controller.

Abstract: A data processor which realizes an AV data transmitting/receiving system of a lower cost. A reception buffer monitor circuit (21) monitors the quantity of received data stored in a reception buffer (6). When a stored data quantity increases above the upper threshold value, the circuit (21) sets the frequency of a reception clock generated by a reception clock generating circuit (8) at a higher frequency. When the stored quantity decreases below the lower reference value, the reception clock frequency is set at a lower frequency. An AV decoder (7) decodes AV data supplied from the reception buffer (6) on the basis of a reception clock supplied from the reception clock generating circuit (8). This invention is applied for a television transmitting/receiving system which transmits and receives television broadcasting signals.

Abstract: A data processing apparatus constituting a low-cost audio/video data transmission and reception system is disclosed. A reception buffer monitoring circuit 21 monitors the size of receiver data being accumulated in a reception buffer 6. When the size of accumulated data is found to become higher than a high threshold, the circuit 21 causes a reception clock generation circuit 8 to generate a reception clock with a higher frequency. When the accumulated data size becomes lower than a low threshold, the reception clock is generated with a lower frequency. Based on the reception clock fed from the reception clock generation circuit 8, an audio/video decoder 7 decodes the audio/video data coming from the reception buffer 6. This invention applies advantageously to a television transmission and reception system for transmitting and receiving TV broadcast signals.
