Abstract

The invention discloses a DVB-based data processing and reading method, a server, a terminal and a system. The data processing method comprises the following steps of: cutting a data file and formingdata nodes; adding a data packet header to each data section; checking and calculating the data sections added with the data packet headers; packaging and cutting the verified and calculated data sections to obtain a processing file. The data reading method comprises the steps of obtaining a processing file; verifying, unpacking and packaging the processing file to obtain a data file; reading thedata file. A data file is segmented, cut and packaged through a data processing method based on DVB, a processing file is generated, and the integrity of data is ensured; the processing file is unpacked through the DVB-based data reading method to generate a data file, and IP networking playing is performed to realize a local video-on-demand function.

Description

technical field [0001] The invention belongs to the field of multimedia technology, and in particular relates to a DVB-based data processing and reading method, a server, a terminal and a system. Background technique [0002] With the improvement of people's living standards, almost every household is equipped with digital TV sets and digital TV set-top boxes to meet people's daily needs for watching audio and video programs. At present, the digital broadcasting set-top box provides a way of viewing live data programs, but there is no better solution for downloading and storing large-capacity data, which is not convenient for realizing the functional requirements of users on demand. Contents of the invention [0003] The purpose of the present invention is to provide a DVB-based data processing, reading method, server, terminal and system, which solves the problem that the existing digital broadcast set-top box is not convenient for ordering. [0004] The invention provid...
