Abstract: A satellite broadcast receiving system is disclosed, in which when each receiver transmits control pulse to a change-over divider via a signal cable, the change-over divider selects a desired broadcast signal in response to the control pulse, which is led to its output terminal, then transmitted to each receiver via the signal cable.

Abstract: Impedance adjusting elements for a microstrip circuit employing a signal transmission line (6) connected to an active circuit element and at least one impedance matching element, such as a parallel-connected open-ended stub (11), are formed of one or more wire elements (21,22) arranged in proximity to the transmission line (6) and the open-ended stub (11) and connected at one end to a ground plane on a side of a substrate opposite to the transmission line (6). The free ends of the wire elements (21, 22) can be freely moved, thereby to adjust the spacing of the wire elements from the signal transmission line (6) and open-ended stub (11) and adjust the angle of intersection of the wire elements and the signal transmission line and open-ended stub, so that the effective impedances of the circuit can be controlled.

Abstract: An innovative but easy to use on-line guide is provided to provide the user of a multiple channel television broadcast system a wealth of programming information in a simple format that is easy to understand. The guide enables the user to easily select a particular program to watch. In particular, when the guide is presented to the user, the guide covers only a portion of the actual television screen or display. The remaining portion of the television screen continues to broadcast the audio and video of the currently selected program. As a user scans through the guide and moves the pointer from one station to another, the system responds by automatically tuning to the channel pointed to by the pointer and provides the audio and displays the video in the portion of the screen not covered by the guide. Furthermore, a written description of the program currently broadcasted on a station that the cursor currently points to is also shown. In addition, the system provides an innovative mechanism to enable the user to scan program information of channels that the user has designated as his favorite channels. In another embodiment, the present invention presents a program list that is oriented according to the program instead of the channel.
