Method for controlling internal communication of digital television all-in-one machine and digital television all-in-one machine

Abstract

The invention discloses a method for controlling internal communication of a digital television all-in-one machine and the digital television all-in-one machine. The method includes the steps that a first monitoring module of a host records the input data amount and the output data amount corresponding to each caching unit of the first caching module of the host and determines the use state of the corresponding caching unit of the first caching module according to the relationship between the size of the recorded input data amount and the size of the recorded output data amount, a first determination module of a CAM card determines the caching unit which can receive data in the first caching module according to the use state which is received from the host and generated by the first monitoring module, and a first receiving and sending module of the CAM card sends request data to the host and enables the request data to be stored in the determined caching unit of the first caching module, wherein the first caching module comprises at least three caching units. According to the method for controlling the internal communication of the digital television all-in-one machine, by increasing the caching space of the host, the data throughout is improved, the use state of the caching space of the host is timely monitored, the waiting time consumed in the data interactive process between the host and the CAM card is shortened, and the interaction rate is improved.

Description

technical field [0001] The invention relates to the field of digital TV integrated machines, in particular to a method for controlling internal communication of the digital TV integrated machine and the digital TV integrated machine. Background technique [0002] With the continuous advancement of science and technology, people are increasingly dissatisfied with the one-way broadcast digital TV mode, and eagerly hope for a better way to obtain richer information. In this regard, radio and television operators around the world have launched VOD (video on demand, video on demand) and other two-way services with stronger self-selection. As the mainstream TV product in the market, the digital TV all-in-one machine is in the process of two-way business interaction with the operation server of the radio and television operator. The host of the digital TV all-in-one machine communicates with the CAM (Conditional Access Module, Conditional access module) card interaction, to meet t...

Problems solved by technology

However, the defect of this existing low-speed communication method is: it is easy to generate data congestion or data interaction waiting between the CAM card and the host, for example, when the first cache space is performing the first data interaction with the second cache space, The first cache space and the second cache space will not be able to interact with the second data, which will cause data congestion and waiting
