MEDIA DATA TRANSFER IN A NETWORK ENVIRONMENT
First Claim
1. In a wireless network environment, a method of transmitting data from a source device to a set of sink devices, the method comprising the steps of:
- (a) said source device broadcasting packet data to said sink devices;
(b) said sink devices collecting packet data and identifying missing packets that have been missed;
(c) upon a sink device detecting a missing packet, said sink device separately requesting the transmission of said missing packet by said source device; and
(d) said source device separately sending missed data packets.

Abstract
In a wireless network environment, a method of transmitting data from a source device to a set of sink devices, the method comprising the steps of: (a) initially the source device broadcasting packet data collectively to each of the sink devices; (b) the sink devices collecting packet data and identifying missing packets that have been missed; (c) upon a sink device detecting a missed a packet, the sink device separately requesting the transmission of the missed packet by the source device; and (d) the source device separately sending missed data packets.

8. A method at a sink device of a set of sink devices of receiving data from a source device, the method comprising:
-
(a) receiving a plurality of packets at the sink device as a result of the source device broadcasting an ordered sequence of packets including audio data; (b) collecting the received plurality and ascertaining whether packets in the sequence have not been received; (c) for a packet that has been ascertained to have not been received, requesting the source device to transmit the not received packet; and (d) receiving the not received packet as a result of the source device transmitting the not received packet.

9. In a wireless network environment, a method at a source device of transmitting packet data from the source device to a set of sink devices, the method comprising the steps of:
-
(a) broadcasting packet data to said sink devices, such that any of the sink devices can collect packet data received from the sink device, identify any packets that have been missed, and upon detecting a missing packet, request the transmission of said missing packet by the source device; (b) receiving one or more requests from a particular sink device to send one or more missing data packets; and (c) sending the one or more missing data packets to the particular sink device. - View Dependent Claims (10, 11, 12, 13)

14. Logic encoded in one or more tangible media for execution and when executed operable to cause a sink device of a set of sink devices to carry out a method of receiving data from a source device, the method comprising:
-
(a) receiving a plurality of packets at the sink device as a result of the source device broadcasting an ordered sequence of packets including audio data; (b) collecting the received plurality and ascertaining whether packets in the sequence have not been received; (c) for a packet that has been ascertained to have not been received, requesting the source device to transmit the not received packet; and (d) receiving the not received packet as a result of the source device transmitting the not received packet.

15. Logic encoded in one or more tangible media for execution and when executed operable to cause a source device in a wireless network environment to carry out a method of transmitting packet data from the source device to a set of sink devices, the method comprising the steps of:
-
(a) broadcasting packet data to said sink devices, such that any of the sink devices can collect packet data received from the sink device, identify any packets that have been missed, and upon detecting a missing packet, request the transmission of said missing packet by the source device; (b) receiving one or more requests from a particular sink device to send one or more missing data packets; and (c) sending the one or more missing data packets to the particular sink device.
