Problems solved by technology
Generally, the compilation speed of the cross compiler is slow, and the corresponding set-top box program needs to be downloaded to the set-top box hardware during debugging. This process takes a lot of time, and using the hardware debugging interface is inefficient and inconvenient to debug. Changes require cross-compilation, downloading, online debugging, etc., which consume a lot of time and reduce work efficiency

The invention discloses a method and a device for the simulation development set-top box functions. An application program of a set-top box is operated, developed and modified by using the set-top box application function simulation device, and a needed operation is transmitted to a PC drive simulation layer by a drive insulation layer for encapsulation and then sent to a real data sending device based on set-top box hardware through a network; the real data sending device is used for monitoring a received communication protocol and then transmits the protocol to a set-top box driver layer to start up corresponding operation after analysis and simultaneously sends real data needed by the set-top box application program to the application program for use; and the real data sending device sends received remote controller keystroke values to the set-top box application function simulation device through the network for the application program to use. The invention utilizes the characteristics of high speed, convenient compiling and simple debugging of the PC machine to accelerate the development progress of the set-top box application program, and can be free from a specific set-top box platform to be suitable for different platforms.
Description
technical field [0001] The invention relates to the field of software development related to application functions in digital set-top boxes, in particular to a PC-based method and device for developing application function simulations of set-top boxes. Background technique [0002] The process of developing application function software for traditional set-top boxes is as follows: figure 1 Shown: First, the application passes the required operations to the driver of the set-top box through the driver isolation layer; the driver of the set-top box performs the corresponding operation or obtains the corresponding data according to the application request; finally, the data required by the application feedback into the application. [0003] Traditional digital TV set-top box application function development is carried out on specific hardware, and program compilation is completed with a specific cross-compiler. Generally, the compilation speed of the cross compiler is slow, a...
