Abstract

Methods, systems, and devices are described for communicating data from multiple data terminals to an aggregator terminal over a communication link having changing link conditions. In some embodiments, source data is received at multiple data terminals, each in communication with an aggregator terminal over a communication link. For example, during a live newscast, one mobile camera may receive live video of an event from a first position while another mobile camera receives live video of the event from a second position. For various reasons (e.g., as the cameras move) each communication link may experience independently changing link conditions. Each data terminal encodes the source data (or store source data for later encoding) as a function of its respective link conditions, and transmits encoded source data over its respective communication link to the aggregator terminal.

Dependent claims

A link-aware gateway system for communicating data to a plurality of subscriber terminals over at least one communication link with changing link conditions, the system comprising:

a receiver unit that receives a set of source data representing media content;
a profiler unit, executed by one or more processors, that determines an audience metric related to the media content received at the receiver unit;
a link awareness unit, executed by one or more processors, adapted to generate a link condition defining a condition of the at least one communication link;
an adaptive coder unit, communicatively coupled with the receiver unit, the profiler unit, and the link awareness unit, and adapted to encode the source data into an encoded data signal as a function of the link condition and the audience metric;
and
a transceiver unit, communicatively coupled with the adaptive coder unit, and adapted to transmit the encoded data signal over the at least one communication link.

3 more elements

One or more non-transitory processor-readable storage media embodied with instructions for executing on one or more processors and circuits of a device a process for communicating data to a plurality of subscriber terminals over at least one communication link with changing link conditions in a link-aware gateway system, the process comprising:

receiving a set of source data representing media content;
determining an audience metric related to the media content;
generating a link condition defining a condition of the at least one communication link;
encoding the source data into an encoded data signal as a function of the link condition and the audience metric;
and
transmitting the encoded signal over the at least one communication link.
