A client receives streaming data according to Moving Picture Experts Group-Dynamic Adaptive Streaming over HTTP (MPEG-DASH) standard. The client includes a transmitter which transmits a Media Presentation Description (MPD) request or a segment request to a server, and a receiver which receives an MPD specified in the MPD request and a segment specified in the segment request. The MPD request contains information requesting transmission of an initialization segment by a push. The receiver receives the initialization segment transmitted by the push.

Client, server, reception method and transmission method complied to moving picture experts group-dynamic adaptive streaming over HTTP standard

A communication method includes executing a cyclic block permutation for a codeword generated based on a quasi-cyclic parity-check code including a repeat-accumulate quasi-cyclic low-density parity-check code, where the cyclic block permutation is permutation of cyclic blocks within the codeword, and mapping each bit of the codeword for which the cyclic block permutation is executed to any one of constellation point of a non-uniform constellation.

Communication method and communication device

The present invention relates to transmission and reception of digital broadcast in a digital broadcast network supporting a configuration of multiple physical layer pipes (PLPs). In particular, signalling parameters relating to a complete PLP are transmitted within layer 1 signalling related to the PLP. The baseband frames mapped on the pipe are configured according to this layer 1 signalling in the same way at the transmitter as they are demapped on the receiver side. The baseband frames are transmitted and received without including these parameters, in particular, at least one of parameters indicating (i) an input stream format, (ii) a single or a multiple input stream, (iii) constant or adaptive coding and modulation, (iv) presence of input stream synchronization, (v) presence of null packet deletion, or (vi) input stream identifier.

A demultiplexerroutes only one or more transport stream packets with a single packet identifier value to each physical layer pipe. A header compression unitreplaces the packet identifier of the transport stream packet with a short packet identifier of one bit length indicating at least whether the transport stream packet is a NULL packet.

Transport stream packet header compression

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.
