Claims (18)

1. In an audio-visual (AVI) receiver, a data stream containing AVI instructions and control signals is received. The control of these AVI instructions involves several steps: loading the AVI instructions into memory in response to their presence in the data stream; initiating control of the loaded AVI instructions; monitoring the data stream for specific signal data sets; and stopping and unloading the AVI control instructions from memory in response to the detection of a specific signal data set containing an end-of-control signal. 2. The method pursuant to claim 1, in which the control termination signal in the said data stream is represented by the control termination signal data stream. 3. The method under claim 1 also comprises the following steps: pausing control of the AVI instruction set in response to a pause control signal in the data stream, where the pause includes pre-conditioning the control of the AVI instruction set to be paused and dumping the AVI instruction set from memory; and resuming control of the previously paused AVI instruction set in response to a next control signal in the said data stream, where resuming control includes reloading the previously paused AVI instruction set from the said data stream and pre-conditioning the control with the information stored when the previously paused AVI instruction set was paused. 4. The method under claim 3 where the pause signal in the data stream is represented by a pause signal repeater data stream during the pause period, and the subsequent control signal is represented by a pause signal repeater data stream interruption. 5. In accordance with claim 3, the temporary control interruption signal in the data stream is represented by the temporary control interruption signal data stream, and the subsequent control signal is represented by the subsequent control signal data stream. 6. In an integrated audio-visual (AVI) receiver that receives a data stream containing a directory and AVI instructions with corresponding directory identifiers, the method for controlling the execution of the AVI instructions consists of steps: loading the AVI instructions into memory in response to their presence in the data stream; initiating the execution of the loaded AVI instructions; monitoring the data stream for AVI instructions that differ from the controlling AVI instructions; and interrupting and minimizing the controlling AVI instructions when such instructions differ from those detected in the data stream. Where minimization includes relocating the controlling AVI instructions from that memory. 7. The method under claim 6, where the procedure for interrupting and minimizing the AVI instruction set controlling the execution, consists of the following steps: terminating the AVI instruction set; storing the identifier of the AVI instruction set in that block of memory; storing the control section and environment of the AVI instruction set at the time of execution in that block of memory; and expelling the said AVI instruction set from that memory. 8. The method under claim 7, in which the AVI instruction loading procedure consists of the following steps: loading the AVI instruction into memory; searching for previously stored memory blocks for a block containing an identifier appropriate for the loaded AVI instruction; and, if a suitable memory block is found, calibrating the control section and environment for the loaded AVI instruction to match the control section and environment for the corresponding AVI instruction stored in that memory block. 9. The method under claim 8 also includes, after the configuration process, keeping the loaded AVI commands in an inactive section until triggered by user input. 10. The method under claim 9 also represents an interactive set of instructions, showing that the AVI instructions have been loaded but are not being executed. 11. The method under Claim 1, where the data stream also includes control signals and comprises the paused execution steps of the AVI instruction set in response to a pause control signal in the data stream and the resumption of the previously paused AVI instruction set in response to the next control signal in the data stream. 12. In an integrated audio-visual (AVI) receiver, a data stream containing AVI instructions and control signals is incorporated, along with a control unit to manage the operation of the AVI instructions. The control process for the AVI instructions involves the following steps within the control unit: loading the AVI instructions into memory in response to their presence in the data stream; sending a trigger message to the AVI instructions in response to user input; sending an exit message to the AVI instructions in response to an end signal in the data stream; sending a suspend message to the AVI instructions in response to a pause signal in the data stream; and sending a continue message to the AVI instructions in response to the next control signal in the data stream. These are some of the control actions performed within the AVI instructions. The inactive sector, where the AVI instruction set is not executing; the active sector, where the AVI instruction set controls the operation; and the suspended sector, where the control of the AVI instruction set is temporarily paused. Entry into the inactive sector is initiated in response to the loading of the AVI instruction set into memory. The suspension of control and the detachment of the AVI instruction set from the control unit are initiated in response to an exit message. In the inactive state, entry into the active sector is initiated in response to an activate message. In the active state, entry into the inactive state is initiated in response to an activate message, and entry into the suspended state is initiated in response to a suspend message. In the suspended state, entry into the active sector is initiated in response to a resume message, and entry into the inactive state is initiated in response to an activate message. 13. The method pursuant to claim 12, whereby the pause signal in the data stream is represented by a pause signal data stream that repeats the pause signal during the pause period, and the next control signal is represented by a non-pause signal data stream, and the pause message transmission procedure in the operating controller consists of the pause message transmission procedure in response to the first pause signal data stream, and the continuation message transmission procedure in the operating controller consists of the continuation message transmission procedure after a specified period has elapsed during which no more pause signal data streams are received. 14. The procedure under claim 12 where the pause signal in the data stream is represented by the pause signal data stream and the next control signal is represented by the next control signal data stream, and the pause message transmission procedure in the operating controller consists of the pause message transmission procedure in response to the pause signal data stream, and the continuation message transmission procedure in the operating controller consists of the continuation message transmission in response to the next control signal data stream. 15. In an integrated audio-visual (AVI) receiver, one selectable stream from a number of user-controlled data streams is chosen. Each stream contains an AVI instruction set with an indicator and control signals. The receiver's control mechanism consists of a control unit to manage the AVI instruction set. The control mechanism involves the following steps in the control unit: loading the AVI instruction set into memory in response to the availability of one of the selected AVI instruction sets from the data streams; storing an indicator of the loaded instruction set in the appropriate memory location; detecting a pre-stored block in memory containing the least significant AVI instruction set indicator; and if the block's indicator matches the indicator of the loaded AVI instruction set, adjusting the control and environment of the newly loaded AVI instruction set to the appropriate block's control and environment. Finally, an activate toggle message is sent to the AVI instruction set in response to user input. The exit message is sent to the AVI instruction set in response to an end signal from a selected control element of that data stream. The suspend message is sent to the AVI instruction set in response to a pause signal from a selected control element of that data stream. The continue message is sent to the AVI instruction set in response to a continue signal from a selected control element of that data stream. The minimize message is sent to the AVI instruction set in response to the presence of an AVI instruction set in a data stream that follows the indicator at the appropriate location in memory. Within the AVI instruction set, the control consists of an inactive section where the AVI instruction set is not executing, an active section where the AVI instruction set is controlled, a suspended section where the control of the AVI instruction set is temporarily paused, and a minimize section which comprises the AVI instruction set suspension step, followed by the storage of the AVI instruction set indicator and its control elements. The environment of the AVI instruction set in that block of memory, and then the detachment of the AVI instruction set from that memory; entering the non-operating sector in response to the loading of the AVI instruction set into memory; stopping control; and detaching the AVI instruction set from memory in response to the exit message when in the non-operating sector; entering the active sector in response to the activate message when in the active sector; entering the non-operating sector in response to the activate message; and entering the pause sector in response to the pause message; and when in the pause sector, entering the active sector in response to the resume message; entering the non-operating sector in response to the activate message; and entering the minimize sector in response to the minimize message. 16. The method under claim 15, which involves a storage procedure in the minimization phase of the instruction set, includes a procedure for storing a time interval in a memory block, representing the time period during which data is stored in that memory block. After that time interval, the data stored in that memory block is extracted. 17. The method pursuant to claim 15, whereby the selected control pause signal in the said number of data streams is represented by the control pause signal data stream during the pause period, and the next control signal is represented by the non-control pause signal data stream, and the control pause transmission procedure in the control consists of the control pause transmission procedure in response to the first control pause signal data stream, and the control continuation transmission procedure in the control consists of the control continuation transmission procedure after a specified period during which no control pause signal data streams are received. 18. The procedure under claim 15 where the pause signal is represented by a pause signal data set and the resume signal is represented by a resume signal data set, and the pause transmission procedure in the operator consists of the pause transmission procedure in response to the pause signal data set, and the resume transmission procedure in the operator consists of the resume transmission procedure in response to the resume signal data set.
