A Next Generation Broadcast Platform (NGBP) is disclosed that utilizes 5G software-defined networking (SDN) and network function virtualization (NFV) technologies. The NGBP is designed to enable a new paradigm for broadcasters, wherein the model of fixed wireless spectrum access granted only to the licensees of the spectrum is replaced by a flexible model in which licensed spectrum is pooled together and allocated dynamically to broadcast licensees as well as outside tenants. The NGBP is implemented using SDN / NFV technology, and includes a broadcast market exchange (BMX) entity that allocates the spectrum between tenants based on service level agreements (SLAs) with those users. The NGBP also includes an internet protocol (IP) core and a broadcast centralized radio access network (BC-RAN) which apply the major network functions to broadcaster content in accordance with the determinations of the BMX. The SDN / NFV implementation offers several distinct advantages over NGBP implemented with dedicated network hardware.

The invention relates to a multimedia system for an Android smart television set. The multimedia system comprises a digital television service module, a television operating system media playing module and a digital television playing module. The digital television service module is used for obtaining and storing program information relevant to digital video broadcasting flow. The television operating system media playing module is used for obtaining the program information of the digital video broadcasting flow from the digital television service module and carrying out reconstitution on the media resource locators according to the program information, wherein the program information of the digital video broadcasting flow corresponds to media resource locators transmitted through NGB-H / J application. The digital television playing module is used for carrying out data structure de-encapsulation on the reconstituted locators, and playing the digital video broadcasting flow according to the de-encapsulated data. The multimedia system for the Android smart television set integrates the playing function of digital video broadcasting into an Android multimedia system, and achieves unified call of upper layer application and unified management on various types of media playing by an Android framework layer, and can well support the media functions in radio and television standards of the next generation.

The invention provides a method of forming position patterns of reserved subcarriers of an NGB-W (Next Generation Broadcasting-Wireless) system. Each physical frame in the NGB-W system comprises signaling symbols, data symbols and frame tail symbols, and each kind of symbols is provided with different pilots. The signaling symbols include signaling pilots. The data symbols include scattered pilots, edge pilots and continuous pilots. The frame tail symbols include edge pilots and frame tail pilots. The method comprises the following steps that the positions of the reserved subcarriers are selected from the non-pilot positions of the signaling symbols, the data symbols and the frame tail symbols, wherein positions of the scattered pilots and the continuous pilots, positions three subcarriers right to the continuous pilots, positions six subcarriers right to the continuous pilots, positions nine subcarriers right to the continuous pilots, positions of the edge pilots, and positions of 12 subcarriers on each left edge of the two sub bands of the NGB-W system are removed from the data symbols. According to the method, an effect of reducing PAPR (Peak to Average Power Ratio) can be well achieved by occupying 1% of subcarriers only.

The invention discloses a wave beam forming method of a next-generation broadcast television net, a system and an interacting base station, wherein the wave beam forming method comprises the following steps: the interacting base station receives channel information from a terminal and position information of the terminal; and the interacting base station sends the channel information and the position information of the terminal to a broadcast base station, so that the broadcast base station adjusts antenna parameters according to the channel information and the position information of the terminal. In the wave beam forming method, the power of a transmitter can be reduced and the receiving quality can be improved.
