Transmission rate selection for a network of receivers having heterogenous reception bandwidth
First Claim
Patent Images
1. A method of selecting a data transmission rate for a network of data receivers having a plurality of local reception bandwidths, the method comprising the steps of:
- (a) receiving a report of said local reception bandwidth from each of a plurality of said data receivers;
(b) identifying a plurality of bandwidth clusters from said reports of local reception bandwidth; and
(c) selecting a data transmission rate that minimizes a loss of data for a receiver reporting a minimum bandwidth included in a bandwidth cluster.

Abstract
A method of selecting a data transmission rate for a heterogeneous network clusters the results of reports of local reception bandwidth and determines an appropriate data transmission rate that either minimizes data loss or minimizes a cost function relating distortion and local bandwidth utilization for each cluster.

14. A method of selecting a data transmission rate for a network of data receivers having a plurality of local reception bandwidths, the method comprising the steps of:
-
(a) receiving a report of said local reception bandwidth from each of a plurality of said data receivers;
(b) identifying in said plurality of reported local reception bandwidths a number of clusters equal to a number of data streams to be transmitted;
(c) selecting a data transmission rate for a data stream minimizing a cost function relating a distortion of said data stream and a utilization of said local reception bandwidth; and
(d) repeating steps (b) and (c) following receipt of a predetermined number of said reports. - View Dependent Claims (15, 16, 17)
