Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] The method for wirelessly transmitting data based on radio and television mobile and digital television of the present embodiment includes the following steps:

[0029] 1) The program editing host outputs various types of program file data, and the program file data is fragmented according to certain sorting rules through a dedicated packaging host; then the fragmented data is encapsulated and merged to form a TS format files, and transmit the TS format files through the transmitting equipment according to the digital TV standard of radio and television. The dedicated packaging host in this embodiment is the TS packaging host, see figure 1 . In this embodiment, the sequence of the time tags in the program file data is used for sorting.

[0030] 2) Under the retransmission mechanism, the data in the TS format is received through the vehicle-mounted receiving d...

Abstract

The invention discloses a wireless data transmission method and system based on broadcasting and TV mobile and digital TV. The method comprises the following steps: 1) outputting various types of program file data by a program editing host, converting the program file data into files in a TS format via a specialized packaging host, and transmitting the digital TV standards of broadcasting and TV of the files in the TS format via a transmitting device; 2) obtaining approximately complete effective data in the TS format by a receiving and demodulating device according to a set data unpacking method; 3) storing the effective data in different blocks and different positions; and 4) separately placing the stored complete effective data in the corresponding program file data according to the sequences and the positions, analyzing the types of the files, and performing subsequent processing. The wireless data transmission method and system have the beneficial effects of eliminating mosaic andpicture sluggishness and other phenomena, meanwhile solving the problem of manual uploading of media data, and satisfying the requirements of precise delivery of advertising media files.

Description

Technical field: [0001] 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. Background technique: [0002] 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 image of the city. ...
