Generating method for digital TV dynamic video stream carrying two-dimensional code labels

Abstract

The invention discloses a generating method for digital TV dynamic video stream carrying two-dimensional code labels. A desktop application used for dynamic display is deployed on an application server by a manager, and the rule for dynamically generating video streams is configured; one path of video stream needing to be forwarded is selected, and an instruction is sent to an application streaming server according to configuration; the desktop application is started by the application streaming server, the application streaming server acquires the bitmap / audio information of the desktop application, performs real-time coding to generate video streams and outputs the video streams to an appointed network device address, and the display frame of the desktop application includes two-dimensional codes; the video stream are transmitted to a set top box of a user through a digital TV network and decoded to be played on a TV set of the user; relevant information can be obtained by the user by scanning the two-dimensional codes. According to the method, through the two-dimensional code technology, the problems that manual input is inconvenient and information is single are solved; through the dynamic desktop real-time streaming application technology, the requirement of differentiation display of different targets in different time frames is met, and the operating requirement for real-time / batched video stream generation is also met.

Description

technical field [0001] The invention relates to the technical field of digital television, in particular to a method for generating a dynamic video stream of a digital television carrying a two-dimensional code label. Background technique [0002] In the operation of digital TV, in order to solve the operation problem of one-way digital TV set-top boxes which account for the majority, a VOD program for one-way terminals is proposed, and the typical one-way program for external interaction is the program. [0003] In the external interactive one-way video-on-demand solution, generally a number / character string on the screen seen by the current user is input on the external interactive terminal to identify the current video stream. This method has limitations in several aspects: 1. All information needs to be displayed on the TV. When there is a lot of information, especially when there are multiple information, it will affect the appearance of the screen; 2. All information n...

Problems solved by technology

This method has limitations in several aspects: 1. All information needs to be displayed on the TV. When there is a lot of information, especially when there are multiple information, it will affect the appearance of the screen; 2. All information needs to be manually input by the user on the external interactive terminal. Especially when there is non-digital information, the operation is extremely inconvenient; 3. The production of the stream itself generally adopts the method of making offline files. On the one hand, it cannot meet the differentiated display requirements of different targets at different times; Tens of thousands of offline video files are also difficult
