Patent Searching and Data


Title:
TRANSMITTING DEVICE AND TRANSMITTING METHOD, RECEIVING DEVICE AND RECEIVING METHOD, TRANSMITTING/RECEIVING DEVICE AND TRANSMITTING/RECEIVING METHOD, RECORDED MEDIUM, AND SIGNAL
Document Type and Number:
WIPO Patent Application WO/2001/011889
Kind Code:
A1
Abstract:
From the transmission side, a background and objects (#1 to #3) both constituting an image are transmitted at a transmission rate R/4. On the receiving side, the image is displayed with a spatial resolution and a temporal resolution. When the object (#1) is dragged at time t1 on the receiving side, the transmission of the background and objects (#2 and #3) is stopped on the transmission side and only the object (#1) is transmitted at all the transmission rates R, as shown in Figure 16(A). Thus, on the receiving side, the image including the object (#1) being dragged is displayed with an improved spatial resolution for the object (#1) by sacrificing the temporal resolution of the image.
