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

Abstract

The invention discloses a method and a system for wirelessly transmitting data based on mobile broadcasting and digital television. The method comprises the following steps: 1) outputting by a program editing machine the various forms of program file data; through a specially designed packing machine, converting the program file data into files in TS format; and emitting the digital television standards for the broadcasting of the files in the TS format through an emitting device; 2) through a receiving and modulating device, based on a set data unpacking method, obtaining the almost complete valid data through the data in the TS format; 3) dividing the valid data into blocks and saving them at different positions; and 4) placing the saved valid and complete data into the corresponding program file data in the order at respective positions and performing post-sequence treatment after the types of the files are analyzed. According to the method and the system proposed by the invention, the phenomena of mosaic and picture sluggishness can be eliminated and the problem of manually uploading media data is also solved, which meets the requirement for precise delivery of advertisement 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...
