Abstract
A wireless transmission system for transmitting audio data. The system includes a transmitter which re-frames the audio data into a plurality of packets and wirelessly transmits at least two copies of each packet during substantially non-overlapping periods, and one or more receivers which receive the plurality of packets and assess a quality level of at least one of the copies thereof, so as to extract the audio data from one of the copies having a desired quality level. Preferably, the receivers include respective back-transmitters, which transmit control commands back to the transmitter, responsive to the data.
Claims38
A wireless transmission system for transmitting stereophonic audio data, comprising:
- a transmitter which re-frames and compresses the stereophonic audio data into a plurality of packets, in which each stereophonic frame is re-framed as a pair of compressed monaural data frames, and wirelessly transmits at least two copies of each packet during substantially non-overlapping periods;
- and
- one or more receivers which receive the plurality of packets and assess a quality level of at least one of the copies thereof, so as to extract the audio data from one of the copies having a desired quality level.
A wireless speaker system for audio data, comprising:
- a transmitter which re-frames the audio data in a packet including tuning information and wirelessly transmits the audio data on at least one carrier frequency in accordance with the tuning information;
- and
- at least one speaker, which automatically tunes in to the carrier frequency using the tuning information and plays the audio data.
A method of wirelessly transmitting digital stereophonic audio data, comprising:
- re-framing and compressing the stereophonic audio data such that each stereophonic frame is re-framed as a pair of compressed monaural data frames;
- transmitting at least two copies of the re-framed audio data during substantially non-overlapping periods;
- receiving the at least two copies;
- assessing a quality level of one or more of the at least two copies;
- and
- extracting the audio data from one of the copies.
A wireless transmission system for transmitting data, comprising:
- a transmitter which re-frames the audio data into a plurality of packets and wirelessly transmits the packets;
- and
- one or more receivers which receive the plurality of packets, determine whether the transmitted packets are defective, and convey non-defective packets to be played by a speaker, wherein after receiving a first predefined number of defective packets, the one or more receivers discard a second predefined number of non-defective packets before resuming conveying non-defective packets to the speaker.
