[0051] figure 2 The first embodiment of the high-speed pushing method of digital TV data files based on streaming video of the present invention is shown. The method of this embodiment can push the SI / PSI transmission control part in the digital TV data transmission, so as to realize the control coordination between the system end and the terminal set-top box. See figure 2 , the following is a detailed description of each step in the method of this embodiment.

[0052] Step S10: The content management system automatically generates a list of video files to be pushed.

[0053] Content Management System (CMS, Content Management System) is a common component in digital TV. CMS users will publish (ie push) several different video files every day according to operation. These video files form a video file list in a fixed organization format through CMS.

[0054] Step S11: After receiving the file update notification of the video file list from the content management system, gene...

Abstract

The invention discloses a high-speed pushing method of a digital television data file based on a streaming video and a device thereof, which can realize a high-speed unidirectional cable network datareceiving and transmitting path. The invention has the technical scheme that the method comprises the steps of: automatically generating a video file list to be pushed by a content management system;after receiving a file updating notification about the video file list from the content management system, directly transmitting the video stream, the audio stream and the program time reference stream of a video file to a set-top box by an individual transmission packet identification path by means of transmission packet; and directly using the video file after the set-top box receives the videofile.

Description

technical field [0001] The invention relates to a high-speed push technology of data files in the field of digital television, in particular to a method and a device for applying a method originally applied to streaming video live broadcast to data file transmission in a digital television one-way network. Background technique [0002] At present, the data and file transmission of the one-way digital TV cable network are mainly based on the DC and 0C methods of DSMCC, that is, the data to be transmitted is packaged by using the Section method, and the packaged data is delivered by the carousel method. into the wired network. After the terminal set-top box receives the data packet, it analyzes the Section, and splices the valid data in each data packet, and finally forms a valid data file on the set-top box. This method causes the defect of following three respects, is respectively: 1) terminal set-top box will carry out the analysis of Section and the splicing of effective ...
