1. An in-flight entertainment system comprising:
a server including a processor, the processor operating under an operating system; and a server/client interface that interfaces with the server and a display unit, the server/client interface to retrieve a specified data block requested by the display unit, wherein the server/client interface sends a command to a storage device controller of the server to retrieve the specified data block from a storage device under the control of the server, and the server/client interface operating based on the server/client interface's control logic and independent of the processor operating under the operating system, wherein the server/client interface receives a packet that is sent by the display unit, the packet includes a header and a load, the header includes a destination address and a source address, wherein the server/client interface parses the packet to identify where the requested data block is located in the storage device, the server/client interface sends a command to a storage device controller to retrieve the specified data block, the in-flight entertainment system further comprising a first-in-first-out (FIFO) queue, wherein the storage device controller transfers the retrieved specified data block to the FIFO queue, wherein the control logic of the server/client interface retrieves the specified data block from the FIFO queue, retrieves the target address to generate a return header for a return packet to transport the specified data block, wherein the target address of the return packet is an address of the display unit, wherein the server/client interface comprises a finite state machine that is included in the server/client interface's control logic. |
