Source note
Storage capacity, operating system and video codec list are not stated in this document. LAN is described as a 'Fast Ethernet port' (p4). The player drives the display only through its 8 on-board HUB75 interfaces (J1~J8, 'connect the display unit'): the interface description lists no output network port, so the number of Ethernet outputs is recorded as 0. asyncPlayback is recorded from the play modes the document lists (plug and play content and program updating from USB drive, command and program schedules); the document does not use the word 'asynchronous' and lists no video input.
