Abstract: Aspects of the subject disclosure may include, for example, receiving a request for recording a real-time media presentation of a live event accessible by way of a direct broadcast satellite service, wherein the request is associated with equipment of a subscriber of the direct broadcast satellite service. A source of the real-time media presentation is identified and monitored to determine whether the live event has ended. A termination is facilitated of the recording of the real-time media presentation of the live event by the equipment of the subscriber responsive to the determined end of the real-time media presentation of the live event. Other embodiments are disclosed.

Abstract: An input-output subsystem for relieving the housekeeping functions of a main host computer and for controlling and transferring data between selected peripheral terminal units and the main host computer. The host computer system connects to a base module through a message level interface bus. The base module houses a plurality of data link processors, each of which controls data transfers to and from a specific peripheral terminal unit. The base module connects all data link processors with a common backplane and provides a distribution control card for connecting and disconnecting selected data link processors to the host system. The base module includes a maintenance card which provides maintenance and diagnostic functions for the data link processors in the base module.

Abstract: An input-output subsystem for the handling of data-transfer operations in a digital data processing system. The I/O subsystem provides a series of I/O controller-processors, designated as Line Control Processors, which are organized into groups to form a Base Module. A plurality of such Base Modules are organized to work with a main system interface unit called an Input-Output Translator which is part of the main host system comprising a processor and main memory. The Input-Output Translator (IOT) provides direct memory transfers to and from any connected Line Control Processor independently of the main processor. This arrangement simplifies the expansion of system capability for handling a greater number of peripheral devices on a simple economic basis while increasing data-transfer rates and reducing access errors in individual transfer operations.

Abstract: An Input-Output Interface Data-Transfer Control Unit, designated as a Line Control Processor, which provides the execution of instructions in accomplish data transfers between a main data processing system and a plurality of different types of peripheral devices. Further, said Line Control Processor provides for the buffering of at least two complete blocks of message data, thus to prevent access errors, since complete record length message transfers can occur in any given data-transfer cycle. The Line Control Processor operates with a standard communications and control discipline which makes the eccentricites of various types of peripheral units transparent to the main system. The Line Control Processor executes data-transfer instructions within the overall system thus relieving the central processor of an involvement in these tasks.

Abstract: A sub-interface system within an Input-Output Subsystem of a digital data processing system. The interface subsystem comprises a Main System Interface of a central processing unit working with the distribution-control means of a Base Module housing a group of Line Control Processors (individual Intelligent I/O Interface units) dedicated to a specific peripheral device. The Main System Interface is designated as an IOT, or Input-Output Translator, and translates input-output instructions into proper form for delivery to a particular intelligent interface unit which can execute the instructions. The IOT provides a data link identifier to identify each particular data-transfer transaction and receives result information from the Line Control Processor and Base Module to keep the Main System informed of the status or completion of each individual data-transfer operation.
