The invention is applicable to the technical field of a digital television and provides a software upgrading system and a digital television receiving terminal of the software upgrading system, the system includes a loading upgrading unit and a software upgrading unit which carries out the on-line upgrading of the software in the application program of the digital television receiving terminal. the software upgrading unit includes an upgrading judging and testing module that is used for testing and judging whether the software upgrading notice is received in real time; and an upgrading processing module used for obtaining the upgrading data from frequency points, in which upgrading code stream is positioned, for recombining and storing the upgrading data and for carrying out the upgradingof the software when the software upgrading notice is received. When the terminal needs to upgrade the software, the upgrading data is obtained from the upgrading code stream and is recombined and stored, so as to realize the software upgrading; the transmitting stream of the program is obtained from the program frequency points and the program is continuously transmitted to the user, thereby realizing the non-interference between the program playing procedure and the software upgrading procedure.
Description
technical field [0001] The invention belongs to the technical field of digital television, and in particular relates to a digital television receiving terminal and a software upgrading system thereof. Background technique [0002] In the prior art, when upgrading over the air (Over The Air, OTA), the terminal stops the currently playing video program, and resumes playing the video program after the upgrading is completed. [0003] Application program APP and system upgrade software (Loader for OTA) are two independent software modules, which are stored in different locations specified in the storage module (such as Flash). The two programs cannot be run at the same time, and can only be downloaded by the upgrade unit Perform software upgrades, and only the application modules can be upgraded. [0004] The main process of OTA upgrade mainly includes the following steps: [0005] Step 1: When it is found that the terminal system software needs to be upgraded, for example, th...
