Dual-Path Channel Reception for Glitch-Free Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional satellite television systems face limitations in efficiently transitioning between video and network channel modes, leading to power consumption issues and potential glitches during mode changes.
Innovation Solution
A communication device with a wideband and narrowband path, utilizing a wideband tuner for multiple channels and a narrowband tuner for single channels, along with a crossbar for signal selection, enables seamless transitions between modes by configuring the device to power down unnecessary paths, thereby optimizing power usage and maintaining continuous network channel reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a single-band tuner is used to receive network channels, then power consumption is reduced, but the ability to receive multiple video channels simultaneously is limited
Solution Approach 1:
The receiver is divided into two independent tuning paths: a wideband path for receiving multiple video channels and a narrowband path for receiving network channels. This segmentation allows each path to be optimized for its specific function, enabling the narrowband path to consume less power while the wideband path handles video channel reception.
Solution Approach 2:
The narrowband path is designed to be multi-functional by capable of receiving both network channels and video channels, though it is primarily optimized for network channel reception to save power. This universality allows flexible operation modes where the system can choose the most power-efficient path for each reception task.
2Use of energy by moving object
If the receiver transitions from wideband to narrowband mode, then power consumption is reduced, but reception continuity may be affected
Solution Approach 1:
Before transitioning from wideband to narrowband mode, the system pre-tunes the narrowband path to the desired network channel frequency. This preliminary action ensures that when the transition occurs, the narrowband path is already ready to receive the channel continuously, preventing reception interruptions or glitches.
Solution Approach 2:
The crossbar switch acts as an intermediary between the wideband and narrowband paths, enabling seamless signal routing. During mode transitions, the crossbar manages the switching between paths to maintain continuous network channel reception while the system transitions from wideband to narrowband operation.
3Adaptability or versatility
If both wideband and narrowband paths are used simultaneously, then channel reception versatility is improved, but device complexity increases
Solution Approach 1:
The receiver architecture is segmented into distinct wideband and narrowband paths with dedicated tuners and processing circuits for each. This segmentation organizes the complexity by separating functions, making the system more manageable and easier to implement while maintaining high versatility.
Solution Approach 2:
The system dynamically switches between wideband and narrowband paths based on operational requirements. The crossbar switch and control logic enable the system to adapt its configuration in real-time, activating only the necessary paths for each reception task, which manages complexity through dynamic rather than static operation.

AI summary
Methods and systems for multi-path video and network channels may comprise a communication device comprising a wideband path (WB) and a narrowband path (NB), wherein the WB may be operable to receive a plurality of channels and the NB may be operable to receive a single channel. Video channels and a network channel may be received in the WB when the device is operating in a first stage. Video channels and a network channel may be received in the WB and the network channel may also be received in the NB when the device is operating in a second stage. The network channel may be received in the NB when the device is operating in a third stage. The reception of the network channel from both the WB and the NB may enable a continuous reception of the network channel in a transition between the first and third stages.
