Abstract: The present disclosure relates to a retransmission device, a retransmission method, a reception device, and a reception method that enable more appropriate processing of control information.
Provided is a retransmission device that includes: a reception unit that receives a broadcast signal of a first broadcasting system; a conversion unit that converts first control information transmitted in a physical layer defined by the first broadcasting system into second control information to be transmitted in an upper layer, the upper layer being a layer higher than a physical layer defined by a second broadcasting system different from the first broadcasting system; and a transmission unit that transmits a broadcast signal of the second broadcasting system. The present disclosure can be applied to, for example, a retransmission device that retransmits digital terrestrial television broadcasting.

Abstract: The present disclosure relates to an information processing apparatus and method capable of suppressing an increase in load of reproduction processing.
The metadata including the spatial configuration information of the subgroup and the dependency information of the subgroup and the layer-group is generated on the basis of the bitstream of the geometry of the 3D data, and the file storing the bitstream and the metadata are generated. Further, on the basis of the spatial configuration information of the subgroup and the dependency information of the subgroup and the layer-group stored in the file as metadata, a bitstream of the geometry of the 3D data corresponding to the desired layer-group and the subgroup stored in the file is extracted, and the extracted bitstream is decoded. The present disclosure can be applied to, for example, an information processing apparatus, an information processing method, or the like.

Abstract: A first descriptor describes an operation point. The second descriptor is a hierarchy descriptor or a hierarchy extension descriptor. The second descriptor has a hierarchy layer index value equal to a value of the second syntax element. A first value of a first syntax element in the first descriptor specifies that an elementary stream indicated by a second syntax element in the first descriptor, when not present in an elementary stream list, shall be added into the list, and an elementary stream indicated by an index in the second descriptor, when not present in the list, shall be added to the list. Responsive to determining the first syntax element has a second value different from the first value, adding the elementary stream indicated by the second syntax element, when not present in the list, into the list, but not the elementary stream indicated by the index in the second descriptor.

Abstract: A system for multiplexing a transport packet and an Ethernet packet comprises a transport interface for receiving a transport stream comprising the transport packet and a network interface for receiving a network stream comprising the Ethernet packet. The system comprises a packet identifier coupled to the transport interface for filtering the transport stream and selecting the transport packet and a date formatter coupled to the network interface for creating a transport header appended to the Ethernet packet. The system further comprises a multiplexer for receiving the transport packet from the packet identifier, for receiving the Ethernet packet from the data formatter, and for multiplexing the transport packet and the Ethernet packet comprising the transport header.

Abstract: This technology relates to a reception apparatus, a transmission apparatus, and a data processing method for configuring circuits on the receiving side at lower costs.
The reception apparatus includes: a demodulation section configured to demodulate a packet included in each of multiple PLPs of a broadcast stream; and a processing section configured to process the packet demodulated by the demodulation section. The demodulation section and the processing section are interconnected via a single interface. The processing section identifies the PLP to which the packet input via the single interface from the demodulation section belongs on the basis of information for identifying the PLP to which the packet belongs. This technology applies, for example, to receivers supporting an IP transmission method.

Abstract: Described herein are techniques for managing content stored on a distributed network. Content is initially placed onto the network and populated across one or more nodes. The content is distributed in association with decay parameters that define a lifetime for the population of the content on the network. Various communication nodes of the distributed network are configured to process the content decay parameters to determine whether to delete the content during subsequent time periods.

Abstract: The present invention relates to a physical layer signalling in a digital broadcast network. In particular, for a digital broadcast network supporting a configuration with a plurality of physical layer pipes, a type indicator is signalled on physical layer for a pipe, the type indicator indicates the format of the input stream which may specify a transport stream, a generic stream or an IP stream. In addition, per physical layer pipe application of header and/or content compression to the user packet headers of the input stream is signalled. Another physical layer parameters are advantageously provided or extended in order to increase the flexibility and efficiency of the layer 1 signalling.

Abstract: Subtitles can be satisfactorily displayed at the time of RAP reproduction and at the time of variable-speed reproduction.
A video stream that includes a video packet in which a payload has coded image data is generated. A subtitle stream that includes a subtitle packet in which a payload has subtitle information is generated. A multiplexed stream that includes a container packet obtained by packetizing the video stream and the subtitle stream is generated and transmitted. Into a header of a specific container packet in which a payload includes a first byte of the subtitle packet, first identification information indicating that the payload includes the first byte is inserted. For example, this first identification information further indicates a priority of subtitle displaying based on subtitle information contained in the subtitle packet having the first byte included in the payload of the specific container packet.
