Left and right earphones are independently wireless such that the left and right earphones are not physically connected when worn by a user. Each earphone comprises a speaker, a body portion, and an earbud extending from the body portion. The body portion comprises a downwardly extending portion that extends straight downwardly when the earphone is worn by the user, a wireless communication circuit for receiving signals transmitted wirelessly to the earphone from a remote source, a microphone, a rechargeable battery, a memory and a processor. Each earphone is configured to receive from a remote computing device, and store in the memory, a firmware update.

Wireless transport of multiple service versions of a transport framework. First and second information may be processed for transmission, respectively, according to first and second service versions of a transport framework. The first and second information may be encoded using a first type of error correction coding; after processing, the processed first information may include error correction coding according to the first type of error correction coding, while the processed second information may remain uncoded according to the first type of error correction coding. Control information may be generated indicating that the second information remains uncoded according to the first type of error correction coding, which may signal to receivers that the second information is processed according to the second service version of the transport framework. Packets including the processed first information, the processed second information, and the control information may be generated and transmitted in a wireless manner.

Systems and methods are disclosed herein for wireless audio distribution for improved performance. The method can include receiving, at a configurable software-defined hub, a pairing initiation signal to connect the hub with at least one node of one or more configurable software-defined nodes. The method can include receiving, from the at least one node, a plurality of node identifiers; authorizing the at least one node based on a comparison of the plurality of node identifiers and identifier data stored in the hub memory; securely pairing the configurable software-defined hub with at least one authorized node; configuring a software-defined transceiver chain comprising a configurable hub transmitter and an authorized node receiver with a modified Logical Link Control layer and an unmodified Media Access Control layer of an Open System Interconnect protocol, and communicating data in a predetermined format from the configurable hub transmitter to the authorized node receiver.

The present technology relates to a transmission device, a transmission method, a reception device, and a reception method with each of which it becomes possible to perform transmission of control information according to an operation form. The reception device receives first data that includes control information, which includes information necessary for channel selection of a service, and transmission sequence information indicating a sequence in which the control information is transmitted and that is transmitted in a transmission sequence corresponding to the transmission sequence information, and controls processing on second data, which includes data of a component included in the service, on the basis of the control information acquired according to the transmission sequence information. The present technology can be applied, for example, to a television receiver.

A wireless earphone comprises a transceiver circuit for receiving streaming audio from a data source over a local ad hoc wireless network. When the data source and the earphone are out of range, they transition automatically to an infrastructure wireless network. If there is no common infrastructure wireless network for both the data source and the speakerphone set, the earphone connects to a host server via an available wireless network.
