Method and system for wirelessly transmitting data based on mobile broadcasting and digital television

Abstract

The invention discloses a method and system for wirelessly transmitting data based on radio and television mobile and digital TV, including the following steps: 1) Outputting various types of program file data by a program editing host, and converting the program file data into TS format file, and transmit the TS format file through the digital TV standard of radio and television through the transmitting equipment; 2) Through the receiving demodulation device, according to the set data unpacking method, the data in TS format can be obtained to obtain approximately complete and effective data; 3) store the valid data in blocks and locations; 4) put the stored effective and complete data into the corresponding program file data in sequence and position, and analyze the file type Do post-processing. Beneficial effects: Eliminate mosaic and sluggish pictures, solve the problem of manual uploading of media data, and meet the requirements for accurate placement of advertising media files.

Description

[0001] Technical field: [0002] The invention relates to the field of wireless data transmission, in particular to a method and system for wireless data transmission based on radio, television mobile and digital television. [0003] Background technique: [0004] Existing vehicle-mounted multimedia playback systems for buses, subways, and taxis receive real-time audio and video streams of MPEG-2 / H.264 from local radio and television (DVB-T / DTMB) transmitters through vehicle-mounted antennas, and decode and play them in real time through vehicle-mounted set-top boxes. . The playback content is mainly video and audio data. Due to the fact that most of the operating vehicles are in motion and affected by urban high-rises, tunnels and other buildings, radio and television signals have a large number of coverage blind spots, resulting in picture pauses, sluggishness, and a large number of mosaics during picture playback, which seriously affect passengers. It also affects the imag...
