This part of ISO/IEC 14776 defines the SCSI command set extensions to access multimediafeatures for all classes of SCSI devices.The commands specified within this standard define standard access and control of thosefeatures of the device that are used in multimedia applications.The SPC command set and its extensions are transport independent and may be implementedacross a wide variety of environments for which a SCSI command mapping and deliveryvehicle has been defined. To date, these include Fibre Channel, SCSI Parallel Interface, HighPerformance Serial Bus, Serial Storage Architecture and ATA/ATAPI.This command set gives and/or enables the following.a) A definition of the command formats and functions independently of delivery,protocol/signalling or transport mechanism. Architectural constraints regarding commandfunctions, over the various transports are addressed in the document specific to the physicaltransport.b) Standardized access to common Features of SCSI devices employed in multimediaapplications.c) System software/firmware independence across device classes. Thus, different tapedrives, optical media drives and other devices can be added to the system withoutrequiring modifications to generic system hardware and software. Provision is made forthe addition of special Features and functions through the use of vendor-specific options.Reserved Opcodes are provided for future standardization.d) Provides compatibility such a way that properly conforming ISO/IEC 9316 devices mayinter-operate with subsequent devices provided that the system engineering is correctlydone. SCSI protocol extensions are designed to be permissive of rejections by conformingISO/IEC 9316 devices and thus allow the ISO/IEC 9316 device to continue operationwithout requiring the use of the extension.
