Problems solved by technology

Because signalling is typically required relating to each data stream for each frame, the signalling may represent a large overhead per frame in terms of data capacity and receiver power consumption.
As a result, the sampling rate used at the receiver is typically required to be sufficient to receive the whole symbol bandwidth, which places demands on the power consumption of the receiver.

Abstract

Methods and apparatus for transmitting and receiving data having a data stream in a wireless broadcast system are provided. A frame is generated. The frame includes preamble section and a data section. The data section carries the data stream. The preamble section carries signalling information. The frame is transmitted to a receiver. In generating the frame, the data section of the frame is segmented into a plurality of frequency zones, and the data stream is mapped to a frequency zone of the plurality of frequency zones. The signalling information includes segmentation information of the frequency zones.

Description

PRIORITY[0001]This application claims priority under 35 U.S.C. 119(a) to an application filed in the UK Intellectual Property Office on Dec. 13, 2010, and assigned Serial No. 1021113.4, the contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates generally to broadcast systems, and more specifically, to a method and apparatus relating to transmission and reception of data streams in digital video broadcast systems.[0004]2. Description of Related Art[0005]A broadcast system, such as a Digital Video Broadcasting (DVB) system, may transmit data in the form of a sequence of frames. A DVB system may operate according to, for example, a DVB Terrestrial 2nd Generation (DVB-T2) standard, or for example, the following families of standards: Advanced Televisions Systems Committee (ATSC), Integrated Services Digital Broadcasting (ISDB), or Digital Multimedia Broadcasting (DMB). Each frame typically incl...
