Embodiment Construction
[0024] [0022] In order to describe the invention in detail, reference will be made to the examples illustrated in the accompanying drawings. The implementations presented in the following description do not represent all implementations consistent with the claimed invention. Rather, they are merely some examples consistent with certain aspects related to the invention. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
[0025] [0023] Many systems and environments are used to send, process, and receive streaming data. Examples of such systems and environments are devices that include hardware, firmware, software, or a combination of hardware, firmware, and / or software. These systems and environments may be implemented by a number of elements including transmitters, transceivers, receivers, and / or combinations thereof.

The present invention relates to a method of wirelessly transmitting and receiving audio digital signals of the type having a first plurality of blocks with each block having a second plurality of frames, with each frame having a third plurality of subframes, with each subframe having a preamble and a binary data. The method efficiently transmits and recomposes the digital audio signals by searching for the preamble associated with a subframe, which is the first subframe of a frame, with the frame being the first frame of a block, and then transmitting wirelessly only the binary data of each subframe, in each frame, in each block thereafter. In a preferred embodiment, the protocol for the transmission of data calls for each data packet that is transmitted to consist of 512 bytes. The data packet transmitted by the transmitter must be acknowledged by the transmission of an acknowledgement (ACK) packet from the receiver. In the event, the data packet is not received and / or the ACK packet is not received, and transmission must recommence, synchronization is accomplished by the retransmission of data packet immediately after the preamble of the first subframe of the first frame of a block.
Description
technical field [0001] This application is a continuation-in-part of US Patent Application Serial No. 11 / 809,061, filed May 30, 2007, the entire contents of which are hereby incorporated by reference. [0002] Related field [0003] [0001] The present invention relates to methods of transmitting and receiving digital audio data, and, more particularly, the present invention relates to efficient methods of transmitting and recombining audio digital signals. Background technique [0004] [0002] Wireless transmission and reception of streaming data typically includes transmission, processing, buffering, and reception performed in accordance with clock information, such as clock recovery and bit clock data, or in accordance with associated tracking loop information. For example, typical systems measure values such as packet or bit error rate or signal strength in a data receiving device or receiver when selecting the most efficient transmission mechanism / scheme. However, sin...
