A wired broadcasting system for television transmission from a plurality of sources to individual subscriber stations has switching apparatus at a central station actuated by signals at the subscriber station. A four wire cable arrangement to each subscriber provides two control wires and two signal wires. Provision for station selection, audience response and numbers of subscribers is made through use of time signals passed through the control wires. Provisions for accepting charges and recordi...

A television broadcasting method and apparatus. The broadcasting method generally includes the steps of multiplexing signals from a plurality of channels over a single carrier frequency, and transmitting the multiplexed signals to a reception circuit. The multiplexed signals are then demultiplexed at the reception circuit. The demultiplexed signals are then separated into separate channels, and then stored for a predetermined period of time. The signals of the selected channel are then decompres...

A radio broadcasting system includes a transmitter which transmits a program signal such as music on one channel, periodic message signals such as advertising commercials on another channel and a plurality of code signals of different frequencies occuring in time at the beginning of selected ones of the message signals. A plurality of radio receivers each receive the program, message and code signals and include means for audibly reproducing the program and message signals. Each receiver include...

A hybrid coupling transformer system is used in wired broadcasting systems with two transformers coupled through a pair of series windings on the respective transformers carrying TV signals. A second winding is coupled in series anti-phase and output windings are coupled to subscriber stations. Audio signals are separately connected in some embodiments to centertopped output windings.

A broadcasting receiver for vehicles especially suited for receiving satellite broadcasting signals comprises a base plate rotatable horizontally, a main reflector tiltably attached to the base plate, a sub-reflector attached to the end portion of an arm of which the other end is attached to the base plate so as to be rotatable horizontally, and a signal detector fixed to the main reflector. The vertical angle between the main reflector and the arm are maintained at a predetermined angle, and th...

A broadcasting wave reception antenna have a magnetic core having multiple radial projections extending on a common plane, and respective projections are provided with coils wound on them.

Apparatus and method for broadcasting a data word from a row of broadcasting processing elements of a two-dimensional parallel processing system along the columns thereof to other rows of receiving elements in the system is disclosed. The parallel processing system is of the SIMD type, each such element being connected to at least communicate bits to the element adjacent thereto in its column. The sequence of instructions applied to the processing elements is effective to cause the efficient bro...

Wired broadcasting systems provide for originating programs at the subscriber station for transmissions over the same signal conductors for receiving programs. Central equipment makes the subscriber originated programs available for other subscribers.

Discloses is a broadcasting receiver including: a receiver; a broadcast program output unit; a channel storage unit to store a physical channel correlated to a first virtual channel, the first virtual channel being composed of a first main channel number and a first sub-channel number; a virtual channel acquisition unit to acquire a second virtual channel from the broadcast signal received by the receiver, the second virtual channel being composed of a second main channel number and a second sub...
