Disclosed is a universal profiling device operable to simulate a performance monitoring unit for a heterogeneous system. The universal profiling device includes a main circuit and a storage circuit. The main circuit is configured to execute at least one of multiple steps including an active data collection step and a passive data collection step. The active data collection step registers a callback function for an event of a designated object according to predetermined setting or user setting, and actively calls the callback function to obtain information of the event. The passive data collection step registers the event of the designated object according to the predetermined setting or user setting and thereby receives the information of the event without requesting the designated object, wherein the information of the event is stored in the storage circuit.

Universal profiling device and method for simulating performance monitoring unit

A multimedia streaming and network apparatus is provided that includes a router module, a storage module and a processing module for executing the application program in the storage module to perform the multimedia streaming and network apparatus operation method. A first streaming request packet corresponding to a physical STB is received through a LAN port. A multicast and hardware offload function corresponding to the LAN port is activated. A STB virtual machine is operated to perform a STB function. A second streaming request packet corresponding to the STB virtual machine is received. A multicast and hardware offload function corresponding to the processing module port is activated. A video stream from a remote server is transmitted by the router module through the LAN port and the processing module port respectively to the physical STB and the STB virtual machine to be processed and playback.
