Set-top box platform for separating digital television application software and hardware, and download method

Abstract

The invention discloses a set-top box platform and a downloading method thereof, wherein, application software and hardware of a digital television of the set-top box platform are separated and the set-top box platform consists of two parts of a hardware platform and a software platform. The hardware platform refers to a general digital television set-top box which comprises a set-top box processor chip, a random access memory SDRAM, a program and data memory FLASH and a high-frequency head and other set-top box hardware devices; the software platform comprises an operating system module OS, a hardware drive module Driver, a system software module System Software, a software downloading and upgrading module Boot Loader and an application program interface module API. The operating system module OS and the hardware drive module Driver in the software platform are closely related to the set-top box hardware and are responsible for operating the hardware; the system software module System Software is a basic software which is operated on the set-top box and can call the application software which is developed on the software platform for implementation; the software downloading and upgrading module Boot Loader is responsible for downloading and upgrading the software; and the application program interface module API provides an application interface with the consistent function to an application program.

Description

Technical field [0001] The present invention relates to the field of digital television technology and mobile multimedia, and provides a set-top box platform in which digital television application software and hardware are separated and a download method thereof. Background technique [0002] At present, the development of digital TV technology is a very closed development model: STB chip manufacturers provide chip and software development environments to STB manufacturers, and then STB manufacturers develop application software on this platform. Because the software and hardware of the STB platform are closely integrated and inseparable, any integration and modification of almost all third-party application software such as CA and data broadcasting requires the participation of STB manufacturers. It is difficult for other professional third-party software companies to intervene, which limits the application software. Sources and choices have greatly increased the software devel...

Problems solved by technology

Not only that, but in this highly software-hardware bundling mode, the perfection and upgrade of the set-top box software becomes very complicated. The set-top boxes provided by the set-top box manufacturers can only meet the software requirements before the release of the set-top boxes. After the set-top boxes are used in batches, even if the software is found It is difficult to improve the problems, let alone add new functions to the set-top box

In addition, the high software and hardware bundling mode caused the slow maturity of set-top box software, which restricted the replacement of chips. The earliest set-top box chips in the market were used on a large scale, but they did not use the most advanced chip technology. Digital TV operators What pay more is to use the set-top box chip products that were outdated 3 or even 5 years ago
