1. A system for transmission of data, the system comprising:

  • an aerial based transmission source configured at least to transmit a data signal, the data signal comprising at least one data signal portion corresponding to digital data packets, at least some of the data packets including a source sequence of data components of compressed video data;

    a first receiver configured at least to receive the data signal and to communicate a first relayed sequence of data components corresponding to the source sequence of data components via a communication network;

    a second receiver configured at least to receive the data signal and to communicate a second relayed sequence of data components corresponding to the source sequence of data components via the communication network, wherein the second receiver is positioned a physical distance apart from the first receiver thereby providing spatial diversity; and

    at least one client device, the client device configured to, at least;

    receive the first relayed sequence of data components via the communication network,receive the second relayed sequence of data components via the communication network,choose between data components of the first and second relayed sequences having corresponding sequence identifiers at least in part by comparing quality indicators for at least some of the data components of the first and second relayed sequences,discard the data components not chosen,form a composite data packet stream at least in part by combining the chosen data components in sequence order, wherein the chosen data components comprise those respective data components of the first and second relayed sequences having highest comparative quality indicators, anddecompress the composite data packet stream of compressed video data.
