IPTV Tuner Pre-tuning During Boot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of modern television sets results in prolonged startup times from standby mode to a desired channel or input, due to the need for digital TV tuning, filtering, and decoding, making users wait several minutes to view their desired channel after turning on the TV.
Innovation Solution
Implementing a usage pattern database that pre-tunes the TV to the user's most common channel and input settings based on time and day of week, allowing the tuner and input switch to be activated before the TV is fully booted, thereby minimizing the time to view a desired channel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If digital TV tuning and decoding is implemented to provide advanced features, then the functionality and versatility of the TV is improved, but the startup time increases significantly
Solution Approach 1:
The patent applies preliminary action by pre-tuning the TV to the user's most common channel and input settings before the user actually needs to view content. The system uses a usage pattern database to predict what channel the user is most likely to access and pre-configures the tuner and input switch accordingly, so that when the user turns on the TV, the desired channel is already tuned and ready, eliminating the need to wait for full boot-up and channel selection.
2Ease of manufacture
If the TV uses Linux kernel and higher level programming to implement complex features, then the ease of implementing advanced features is improved, but the responsiveness and boot-up speed deteriorates
Solution Approach 1:
The system performs preliminary channel tuning and input switching before the full boot-up process completes. By using the usage pattern database to predict the most likely channel and pre-configuring the tuner and input switch during the boot process, the TV becomes responsive for viewing content before the higher-level programming fully initializes, thus maintaining ease of feature implementation while improving perceived responsiveness.
3Use of energy by stationary object
If the TV remains in standby mode with minimal power consumption, then the energy efficiency is improved, but the startup time to reach a desired channel increases
Solution Approach 1:
The patent resolves this contradiction by performing preliminary channel configuration during the boot process rather than requiring the TV to remain fully powered on. The system uses the usage pattern database to predict the most likely channel and pre-tunes the TV to that channel during startup, so the user can access their desired content quickly without the TV needing to maintain high power consumption in standby mode.

AI summary
An Internet audio video device receives a command to power up from a standby mode. This causes the device to start a boot process, and while the boot process proceeds. The process determines a next content selection from a usage pattern database. The Internet audio video device is set to the retrieved settings. At completion of the boot process the audio video device is operational at the retrieved settings. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
