Abstract
A method and apparatus for improving the reliability in the synchronous streaming of data from a sender to multiple receivers, especially in networks having a limited bandwidth. The sender is configured to change the format of the data to be sent by segmenting the data into packets having maximum size, and identifying each packet with a message number. The transmit rate of the sender is adjusted according to the throughput bandwidth of the link so as to avoid congesting the link. Each receiver is configured to re-assemble the packets based upon the message number allocated to each packet, and re-create the data in the original format for being read by standard HDJ Radio Exciters. The Receivers may also be configured to keep track of the packet numbers and request re-transmission of lost packets, using the ARQ (Automatic Retransmission Request) scheme.
