Embodiment 1

[0031] Embodiment 1, a kind of digital television data transmission method in this embodiment, comprises the following steps:

[0032] S1. Classify the data information in the digital TV service function, and each category has a corresponding interface in the application program interface layer, and the user sends a request through the interface corresponding to the category of the requested information.

[0033] The application program interface (API) provides the interface for obtaining data corresponding to the Java application. The application program interface layer design in this embodiment adopts the interface design idea to classify the data information in the digital TV service function, and each category is in the There are corresponding interfaces in the application program interface layer, and multiple interface interfaces including conditional access (CA), search, electronic program guide, frequency locking module, etc. are proposed, see figure 1 Shown is the Inte...

Abstract

The invention discloses a method and a system of digital television data transmission. The method comprises the following steps: (1) classifying data information in digital television service function, wherein an application program interface layer of each classification is provided with a corresponding interface, and a user sends a request to a corresponding interface according to the classification of request information of the user; (2) a local view call hierarchy receiving the request from the application program interface layer, acquiring data from a matching layer after analysis, packaging the data from the matching layer, and sending the data to the application program interface layer; (3) the application program interface layer feeding the data to the user. Thus, conveying work of a whole data flow is completed. According to the method of the digital television data transmission, layered structure designs are respectively adopted for the application program interface layer and the local view call hierarchy, clear interfaces are defined between layers, and therefore code coupling degree is reduced, code maintenance difficulty is reduced, and asynchronous data transmission is effectively realized.

Description

technical field [0001] The invention relates to a digital TV data transmission method and system, belonging to the technical field of digital TV. Background technique [0002] Traditional digital TV data transmission is based on the same design language C or C++, which does not involve the data transmission mechanism between C or C++ and JAVA, and cannot complete the application of smart digital TV services. At present, terminal devices based on the intelligent operating system Android are becoming more and more popular, but there are basically no terminal devices that can support traditional all-digital TV services at present. Traditional digital TV services have the characteristics of large data volume and asynchronous transmission. How to transmit digital TV service data stably and quickly between the bottom layer (C language or C++ language) and the application layer (Java language) is the current smart digital TV terminal. problems faced by all. [0003] Some existing...
