Information processing with flexibility in interpretation of a standard is disclosed. In one example, an output unit adds additional information related to the BB packet to output the BB packet to a baseband (BB) packet after an error correction decoding process. The additional information includes at least one of a delimiter, a precision time protocol (PTP), or BB packet information. The BB packet information includes at least one of information indicating whether or not reception of the BB packet is stable, information indicating whether or not there is an error in the BB packet, a packet length of the BB packet, a relative physical layer pipe (PLP) ID of the BB packet, or an absolute PLPID of the BB packet.

The present technique relates to a data processing apparatus and a data processing method each of which enables a burden imposed on processing on a reception side to be reduced. A data processing apparatus produces signaling containing a Null cell number exhibiting the number of Null cells of cells of a sub-frame included in a physical layer frame, and processes the signaling so as for the signaling to be contained in a preamble of the physical layer frame, thereby enabling a burden imposed on processing on a reception side to be reduced. The present technique, for example, can be applied to data transmission complying with the broadcasting standards such as ATSC3.0.

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.

A method of encapsulating data and a single frequency network configured to perform the method are disclosed. A content stream of data packets is received, and the data packets in the content stream are formatted in accordance with a first protocol. Information identifying a container size established for the content stream is received. The data packets formatted in accordance with the first protocol are fragmented and packed to form data units formatted in accordance with a second protocol, and the data units are sized based on the container size. The data units formatted in accordance with the second protocol are encapsulated to form second protocol data packets. The second protocol data packets are provided to a transmitter that is synchronized to one or more transmitters in a single frequency network so that each transmitter in the single frequency network broadcasts a same signal that includes the second protocol data packets.

Systems, methods, and computer program products are provided for improving establishment and broadcasting of communication among mobile computing devices. For example, a method comprises determining a first user accesses a mobile application on a first mobile device of the first user; determining a second user accesses the mobile application on a second mobile device of the second user; and initiating the audio conversation between the first user and the second user, wherein the audio conversation is streamed to a third user who accesses the mobile application on a third mobile device of the third user.
