Drive method and device for smart terminal

Abstract

The invention discloses a drive method and device for a smart terminal. The method comprises the steps of obtaining frontend configuration information; transmitting the frontend configuration information to a frontend drive module through a frontend drive adaptive module; transmitting the frontend configuration information to an I2C bus driver through an I2C drive adaptive module; and driving an I2C device according to the frontend configuration information. The obtained frontend configuration information is transmitted to the I2C bus driver through the frontend drive adaptive module, the frontend drive module and the I2C drive adaptive module in sequence; the frontend drive module communicates with the I2C bus driver through the I2C drive adaptive module and is located in a layer different from that where the I2C bus driver is. When frontend debugging and test are carried out, the development and maintenance efficiency of the smart terminal can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of set-top boxes, and in particular, to a driving method and device for an intelligent terminal. Background technique [0002] Frontend (front end) is a key component of multimedia equipment such as digital TV set-top boxes. It is divided into two parts: Tuner (tuner) and Demodulator (demodulator). ), a band-pass filter, an intermediate frequency amplifier, an AGC (Automatic Gain Control, automatic level control) circuit and a phase shifter, which are used to amplify, filter and secondarily convert the received RF signal to convert it into the second IF signal. The IF signal of the Demodulator is sent to the demodulation module after filtering, amplifying, and A / D converted to a digital signal, and finally outputs the TS stream. [0003] There are many types of Frontend. According to different transmission media, Frontend has different standards such as satellite set-top box, terrestr...

Problems solved by technology

Therefore, every time you transplant, develop and debug a new platform, or switch to a new Frontend, you need to debug from the bottom up, involving multiple files such as kernel configuration files, kernels, driver libraries, and adaptation libraries, which need to be developed and maintained. The workload is heavy and the efficiency is low. In addition, some manufacturers do not open the driver source code of Frontend, which makes it more inconvenient to transplant.
