Content Receiver Low-Power Mode via Scheduling Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Content receivers, such as set-top boxes, continue to consume power even when in a standby mode due to maintaining functionality for receiving scheduled transmissions, leading to inefficient power usage.
Innovation Solution
Implementing a method where a content receiver uses scheduling data to determine when primary data is available and powers down most components, only activating necessary hardware at the designated time to receive and process the data, utilizing a secondary processor to manage power states and wake the device for scheduled operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the content receiver maintains continuous power to receiving elements for receiving scheduled transmissions, then the reliability of receiving data is improved, but the power consumption increases
Solution Approach 1:
The content receiver obtains scheduling data in advance that indicates when primary data will be transmitted, allowing the device to wake up only at those specific times. This preliminary knowledge enables the receiver to remain in a low-power state during intervals between scheduled transmissions while ensuring it is ready to receive data when needed, thus resolving the contradiction between maintaining receiving reliability and reducing power consumption.
2Use of energy by moving object
If the content receiver powers down components during standby mode, then the power consumption is reduced, but the ability to receive scheduled transmissions is compromised
Solution Approach 1:
The receiver obtains scheduling data beforehand that specifies exact transmission times, allowing it to power down components during standby while waking up precisely when primary data is scheduled to arrive. This preliminary scheduling information enables reliable reception without continuous power consumption.
Solution Approach 2:
A low-power wake-up receiver or alarm mechanism acts as an intermediary that monitors for scheduled transmission times and triggers the main receiving components to activate. This intermediary enables the system to maintain reliability by detecting scheduled transmissions while keeping main components powered down during standby periods.
Data Source
AI summary
A method, system and apparatus for interacting with scheduling data and primary data. A content receiver may receive scheduling data and extract, from the scheduling data, a time at which primary data is available. The content receiver may enter a de-powered state until the time, at which point it powers up. The content receiver may receive the primary data at the time and process it as necessary. Following processing, the content receiver may again power down.
