Embodiment Construction

[0028] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.

[0029] refer to image 3 , an RIA-based high-performance Web transmission network management system in this embodiment includes a wireless receiving module 110 , a signal processing module 120 and a signal interface module 130 . The wireless receiving module 110 receives radio frequency signals carrying audio and video services. The wireless receiving module 110 includes an antenna. The signal processing module 120 performs TDS-OFDM demodulation, decoding and synchronization processing on the radio frequency signal received by the wireless receiving module 110 to obtain audio and video signals, and outputs the audio and video signals. The signal interface module 130 receives the audio and video signals output by the signal processing module 120 .

[0030] In detail, refer to Figure 4 , the signal processing module 12...

Abstract

The invention discloses a high-performance Web transmission network management system based on RIA. The system comprises a wireless receiving module, a signal processing module and a signal interfacemodule. The wireless receiving module receives radio frequency signals carrying an audio and video business. The signal processing module carries out the TDS-OFDM demodulation, decoding and synchronous processing of the radio frequency signals received by the wireless receiving module, obtains audio and video signals, and outputs the audio and video signals. The signal interface module receives the audio and video signals outputted by the signal processing module. The system provided by the invention can receive and process the radio frequency signals at high reliability, so as to obtain the high-quality audio and video signals. The system is high in integration degree, is small in convergence errors, and is short in convergence time.

Description

technical field [0001] The present invention relates to the technical field of digital television, and more specifically relates to an RIA-based high-performance Web transmission network management system. Background technique [0002] At present, Digital Television Terrestrial Broadcasting (DTTB) has reached the achievable stage. Currently, there are three main DTTB transmission standards published in the world: the ATSC standard formulated by the American Advanced Television System Committee (ATSC) , Digital Video Terrestrial Broadcasting-Terrestrial (DVB-T) in Europe, and Integrated Service Digital Broadcasting-Terrestrial (ISDB-T) in Japan. Based on in-depth research on these three terrestrial digital TV systems, Tsinghua University proposed a terrestrial digital TV broadcasting transmission system based on Time Domain Synchronous Orthogonal Frequency Division Multiplex (TDS-OFDM) modulation technology. It was adopted by our country and formulated as our country's DTTB ...
