Video Decoding Chip Channel Switching for Lower Idle Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video decoding technologies face high power consumption due to input and output channels remaining active when no video stream is present, leading to inefficiency.
Innovation Solution
Implement a system to detect flag bits indicating video stream presence, controlling input channels to open or closed states based on stream presence, and determining output channels accordingly to reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If input channels and output channels remain in the open state to ensure video decoding functionality, then video decoding capability is maintained, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the input and output channels switchable between open and closed states based on operational needs. The controller dynamically adjusts the channel states - keeping them open when video streams are present and closing them when no streams are detected, thus adapting the system's operational state to current requirements and reducing unnecessary power consumption.
Solution Approach 2:
The system implements self-service through automatic detection of video stream presence and automated control of channel states. The controller monitors the input channels, detects when video streams are absent, and automatically closes the appropriate channels without manual intervention, enabling the system to self-regulate its power consumption based on actual operational needs.
2Adaptability or versatility
If all input channels are kept in the open state to receive potential video streams, then video stream reception capability is maintained, but power consumption increases
Solution Approach 1:
The system dynamically adjusts the operational state of input channels based on detected video stream presence. When video streams are detected on certain channels, those channels remain open while others are closed, allowing the system to adapt its reception capability to actual needs rather than maintaining all channels in a constant open state.
Solution Approach 2:
The patent applies local quality by treating different input channels differently based on their individual operational status. Each channel's state (open or closed) is determined locally based on whether a video stream is present on that specific channel, rather than applying a uniform state to all channels, thus optimizing power consumption while maintaining necessary reception capabilities.
3Reliability
If output channels remain in the open state to ensure decoded video output, then decoded video output capability is maintained, but power consumption increases
Solution Approach 1:
The controller dynamically controls the state of output channels based on the presence of video streams on corresponding input channels. When no video streams are detected on input channels, the corresponding output channels are closed, eliminating unnecessary power consumption while maintaining the capability to output decoded video when streams are present.
Solution Approach 2:
The system implements feedback control where the controller continuously monitors the state of input channels and uses this information to adjust the state of output channels. This feedback mechanism ensures that output channels remain open only when there is actual decoded video to output, thereby maintaining output capability while reducing power consumption during idle periods.

AI summary
The present disclosure relates to systems and methods for video decoding with a video decoding chip. The video decoding chip may include one or more input channels and one or more output channels. The systems and methods may include detecting a flag bit of each of the one or more input channels. The flag bit of an input channel may indicate a status of receiving its corresponding stream of encoded video data. The systems and methods may include determining an operating state of the one or more input channels based on the flag bits. The operating state of an input channel may include an open state and a closed state of the input channel. The systems and methods may further include determining at least one of the one or more output channels to output the corresponding stream of decoded video data based on the input channels in the open state.
