First Claim
1. A method of selective retransmission for wireless communication of uncompressed video data, the method comprising:
- receiving a data packet from a transmitter over a wireless channel, wherein the data packet comprises a plurality of displayable elements, each displayable element comprising a plurality of portions including a most significant portion and a least significant portion;
wherein the plurality of portions are grouped at the transmitter into a plurality of data groups, wherein the plurality of data groups comprise a first data group and a second data group, the first data group including the most significant portions of each of the displayable elements, and the second data group including the least significant portions of each of the displayable elements;
determining whether the first data group and the second data group is in error; and
requesting retransmission of a selected data group of the plurality of data groups in error according to a quality of service associated with the displayable elements, wherein one or more of the data groups of the plurality of data groups can be included in the request,wherein requesting the retransmission comprises requesting;
retransmission of only the first data group if only the first data group is in error; and
no retransmission if only the second data group is in error.

Abstract
A system and method for wireless communication of data are disclosed. One embodiment of the system includes a transmitter configured to transmit a data packet including a plurality of displayable elements over a wireless channel. Each displayable element includes a plurality of portions including a most significant portion and a least significant portion. The data packet is divided into a plurality of data groups including a first data group and a second data group. The first data group includes the most significant portions of the displayable elements while the second data group includes the least significant portions of the displayable elements. The system also includes a receiver configured to receive the data packet over the wireless channel and to determine whether any of the data groups is in error. The transmitter is further configured to transmit to the receiver: a retransmission packet including a selected data group in error according to a quality of service associated with the displayable elements. One or more of the data groups can be included in the retransmission packet.
