Problems solved by technology

Although the power consumption per unit of calculation can be reduced a lot thanks to the progress of microelectronics technology, in fact, due to the rapid increase in the amount of calculation that the terminal needs to perform, the overall power consumption remains high, or even rises instead of falling, making the battery standby time cannot be extended

Embodiment Construction

[0024] In the present invention, the downlink from the master machine to the slave machine can basically refer to the mode of digital television broadcasting. attached figure 1 , figure 2 A realization method is given respectively.

[0025] At the master machine side, the audio and video signals output to the handset are compressed and coded respectively, and then multiplexed with the control signals that need to be downloaded to the slave machine, and then digitally modulated and coded for the channel, and then transmitted to an appropriate frequency point through appropriate up-conversion , down to the sub-machine.

[0026] The frequency point used for downloading to the handset can be an authorized frequency point, a public frequency point, or infrared light. Among them, infrared is particularly suitable for indoor applications.

[0027] When a master unit is required to be used in conjunction with multiple slave units, multiple frequency points can be used, and more c...

Abstract

The invention is used in the low-power-consumption design of a handheld terminal, and aims to make the handheld terminal have low power consumption by using a primary-secondary machine architecture.

Description

technical field [0001] The invention is used for the low power consumption design of the hand-held terminal, and proposes a solution for reducing the power consumption of the hand-held terminal by adopting a sub-master machine structure. Background technique [0002] Reducing power consumption and improving standby time are an important goal pursued by various handheld terminals. Although the power consumption per unit of calculation can be reduced a lot thanks to the advancement of microelectronics technology, in fact, due to the rapid increase in the amount of calculation that the terminal needs to perform, the overall power consumption remains high, or even rises instead of falling, making the battery standby time Cannot be extended. [0003] Analyzing the power consumption composition of handheld terminal equipment, we can see that a considerable part is used for application processing, and a considerable part is used for remote communication. [0004] Most handheld te...
