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.

An apparatus, method and computer program product are provided for creating a personalized visualization of broadcasting stations that enables a user to quickly identify broadcasting stations that are in line with his or her tastes or preferences. Broadcasting stations may be plotted at specific locations within a personalized visualization based on the categories in which media objects broadcast by those broadcasting stations fall. This location may be continuously updated as the broadcasting stations continue to broadcast additional media objects falling within different categories. A user may similarly be plotted, and continuously updated, within the personalized visualization based on the categories in which media objects reproduced by the user fall. By viewing the personalized visualization, the user may be able to identify which of the broadcasting stations monitored are broadcasting media objects that are most in line with the media objects he or she has been reproducing.

The present invention proposes a method for providing a broadcast service. The method for providing a broadcast service in a broadcast signal transmitter according to the present invention may comprise the steps of: encoding media data to a media stream; creating signaling information for signaling the media stream; multiplexing the encoded media stream and the signaling information; and transmitting a broadcast signal comprising the multiplexed media stream and the signaling information.

There is provided a method of conveying information using a set of first identifiers, the set of first identifiers having a first number, M, of possible values for representing a first number, M, of first information items. The method comprises the steps of partitioning the set of first identifiers into a second number, N, of sub-partitions, wherein the second number, N, of sub-partitions represents the number of possible values required to represent a set of second information items. A sub-partition is used to transmit a second information item while also transmitting a first information item using a first identifier.
