IEEE 1394 Set Top Box device driver

摘要

A device interface for use in a receiver/decoder for a broadcast digital television system in which received signals are passed through a receiver to the receiver/decoder and thence to a television set. The receiver/decoder decodes a compressed MPEG-type signal, and is controlled by a remote controller handset, through an interface in the receiver/decoder. The operation of the receiver/decoder is controlled by a virtual machine (VM) which includes a run time engine (RTE). The receiver/decoder includes a plurality of interfaces to external units. The device interface enables an application run by the RTE to access an IEEE 1394 interface. The device driver may be applied to other interfaces. <IMAGE>
