Abstract
A vehicle entertainment system distributes an executable program in more than one channel of a modulated RF signal by using a plurality of download lines provided between the system file server and the RF modulator. The multiple download lines permit a passenger seat that missed the time window for downloading an executable program to request and download the executable program even before the first download has completed. The multiple download lines also permit downloads of different executable programs to take place at the same time. The vehicle entertainment system further includes a dedicated download processor and a buffer. The dedicated download processor is provided to reduce the processing load of the file server processor, in particular, to take over the task of generating a continuous stream of data responsive to a download request and supplying them to the RF modulator. The buffer provides the dedicated download processor an area where previously retrieved executable program may be stored for subsequent fast access.
