    remove first-encoding-rate data packets from said store at said first encoding rate for decoding to present said real-time presentation to said user at a first level of quality;

    on said store being filled with said first-encoding-rate data to a predetermined level, sending an indication that said level has been reached to said sender;

    operating said sender, on receipt of said indication, to send second-encoding-rate data packets representing subsequent parts of said real-time presentation to said display device, said second encoding rate being higher than said first encoding rate;

    operating said display device to;

    receive second-encoding-rate data packets representing a subsequent part of real-time presentation into said store;
