Abstract

Methods and systems for a novel multi-media macro-network. A Picon media server is connected with variety of high data rate sources including high definition video and audio connections. Picon media server is configured to process the variety of data streams into lower data rate IP packets and dynamically transmit them wirelessly via plurality of channels and antennas to variety of Picon receivers which are configured to congregate the received data packets into the correct signal formats for specific displays.

Claims

1. A method for wireless media transmission, comprising actions of:

receiving multimedia signals;

directing said multimedia signals to respective media processing unit according to its data type;

if said signals constitute a stream of uncompressed and encrypted multimedia data stream, splitting a single stream of uncompressed and encrypted datastream into plurality of substreams;

processing said multimedia signals and said substreams into data packets;

transmitting said data packets wirelessly via plurality of channels.

receiving said data packets wirelessly via plurality of channels;

reverse processing said data packets into data stream; and

sending said data stream to a sink.

4. A method of claim 1, wherein if said data signal is uncompressed and unencrypted datastream, said datastream is first compressed and encoded before being converted into data packets and wirelessly transmitted;

and

after said data packets being wirelessly received, they are first decompressed and decoded, and are directed to a process of packet loss detection and recovery.

6. A method of claim 1, further comprising actions of:

processing, scheduling, and prioritizing said data packets; and

dynamically allocating transmitting channels for said data packets for wireless transmitting.
