Signal processing apparatus and methods
First Claim
1. A method of communicating data to a multiplicity of receiver stations, each of which includes a computer adapted to generate and transmit user specific signals to one or more associated output devices, with at least some of said computers being programmed to process modification control signals so as to modify the user specific signals transmitted to their associated output devices, each of said computers being programmed to accommodate a special user application, comprising the steps of:
- transmitting an instruct-to-process signal to said computers to cause each of said computers to process data in accordance with its associated special user application,transmitting an instruct-to-output signal to said computers at a time when the corresponding user specific information is not being transmitted to an output device,detecting the presence of said instruct-to-output signal at selected receiver stations and coupling said instruct-to-output signal to the computers associated with said selected stations, andcausing said last named computers simultaneously to output their user specific signals to their associated output devices in response to said instruct-to-output signal, thereby to transmit to the selected output devices an output signal comprising said data and said related user specific signals, the output signals at a multiplicity of said output devices being different, with each output signal specific to a specific user.

Abstract
Apparatus and methods for automatically controlling programing transmissions and presentations on television and radio equipment and monitoring the programing transmitted and presented. ("Programing" here means everything transmitted over television or radio intended for communication of entertainment or to instruct or inform.) The apparatus can handle programing transmitted either over-the-air (hereinafter, "broadcast") or over hard-wire (hereinafter, "cablecast"). The apparatus receive transmissions from as many as one hundred or more channels that are sequentially scanned by one or more scanners/switches that transfer the transmissions to one or more receiver/decoders that identify signals in the programing and separate the signals from the programing transmissions. The signals may then be transferred through one or more decrypters. The separated and possibly wholly or partially decrypted signals are then transferred through one or more processors and buffers to external equipment and/or data recorders. The data recorders are adapted to output data to remote sites on predetermined instructions. In all these functions, the apparatus are governed by one or more controllers. The methods co-ordinate and instruct equipment in the transmission and presentation of radio and television programing, especially in multi-media and multi-channel presentations, and in certain other functions.
