Smart TV STR Startup Using Pre-stored Video Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart TVs experience slow startup times due to complex hardware and operating systems, with the Suspend To RAM (STR) quick starting technology being inefficient as it requires setting video display parameters, which takes a long time, especially when the input source changes.
Innovation Solution
A method and system for smart TV startup that involves obtaining video display control parameters from a preset memory during the STR process, setting register groups for video drivers, and releasing a mute state to play video only when the input source matches the stored source, thereby reducing the time needed to set video display parameters and improving startup speed.

Engineering Contradiction Analysis
1Speed
If STR quick starting technology is used to restore system status from memory, then startup speed is improved, but video display parameter setting time increases because register groups must be configured according to input source
Solution Approach 1:
The patent stores video display control parameters and input source information in advance during the last shutdown operation. When the system resumes from STR mode, these pre-stored parameters are directly retrieved and applied without requiring reconfiguration, thereby eliminating the time-consuming parameter setting process while maintaining fast startup performance
Solution Approach 2:
The patent creates a copy of the video display control parameters and register group configurations from the previous operating state and stores them in memory. During STR resume, this copied data is restored and applied directly, avoiding the need to重新 configure parameters and significantly reducing startup time
2Manufacturing precision
If register groups of video drivers are set according to input source of locked signal, then video display accuracy is improved, but startup time increases due to the configuration process
Solution Approach 1:
The patent performs the video driver register configuration in advance during the shutdown phase, storing the configured parameters in memory. Upon STR resume, the pre-configured parameters are directly restored and applied, maintaining video display accuracy while eliminating the time-consuming configuration process during startup
Solution Approach 2:
The system automatically retrieves and applies the previously stored input source and video display control parameters without requiring manual intervention or complex detection processes. This self-service mechanism ensures accurate video display configuration while minimizing startup time

AI summary
Disclosed a smart television starting method, which includes: in a Suspend To RAM (STR) starting process of a smart television, acquiring a signal format and a video display control parameter corresponding to the signal format from a preset memory stored during last shutdown of the smart television after a kernel is recovered completely; setting a register group of each driver associated with video displaying according to the video display control parameter if the stored video display control parameter is obtained; when a signal lock notification sent by a driver layer is received, obtaining a signal format of a current lock signal from the signal lock notification; if the signal format of the lock signal is the same as the stored signal format, releasing a mute state of a to-be-played video corresponding to the current signal and playing the to-be-played video; The disclosure further provides a system for starting smart television.
