摘要： A fully integrated completely wireless mobile media system for digital signage applications receives content from a mobile telephone network. The received content is wirelessly distributed to point of sale locations and wireless local hotspots via IEEE 802.11(n) or later communications protocol. Audio and high definition video are streamed over MIMO RF technology incorporating JPEG2000 or later compression algorithms providing transmission quality up to or better than wired connectivity over a wireless link. The system requires no wired communications infrastructure such that the entire system may travel, or advertising displays are readily relocatable within the retail environment. Media content can be unicast for point to point (single endpoint) or multicast for multi-endpoint delivery. The system supports wireless local hotspot connectivity.
