Wireless Interface Module for Remote DVR Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital video recorder (DVR) systems lack remote control capabilities, making it difficult for users to manage recorded programs and schedule recordings efficiently, especially when not using network personal video recorder (NPVR) services.
Innovation Solution
A method and system for remote control of DVRs using wireless devices, allowing users to query servers for program and DVR data, display this information, and control the DVR by selecting user-operable functions, enabling remote management of recordings and scheduling through a wireless interface module connected to the DVR control module and video content network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users want to control DVR remotely, then user convenience and accessibility are improved, but system complexity increases due to wireless interface and network integration requirements
Solution Approach 1:
The patent introduces a wireless interface module as an intermediary component that bridges the remote wireless device and the DVR control module. This mediator handles the complexity of wireless communication protocols and network integration, allowing users to control the DVR remotely without directly exposing the complex system architecture to end users.
Solution Approach 2:
The system is divided into distinct functional modules: a control module for processing user inputs, a wireless interface module for handling wireless communications, and the DVR system itself. This segmentation isolates the complexity of remote communication capabilities into a separate module, making the overall system more manageable and easier to implement.
2Measurement precision
If direct access to DVR is implemented, then real-time management accuracy is improved, but network bandwidth consumption increases
Solution Approach 1:
The patent extracts and transmits only the specific DVR data that is necessary for remote control functionality, such as recording schedules and program information, rather than transmitting all DVR data. This selective extraction approach maintains real-time management accuracy for critical functions while minimizing network bandwidth consumption.
Solution Approach 2:
The system implements partial real-time access by providing real-time data for critical control functions while using periodic or on-demand updates for less time-sensitive information. This partial action approach balances the need for real-time accuracy with bandwidth conservation.
Data Source
AI summary
At least one server is queried from a wireless device to obtain program data, and to obtain DVR data from a digital video recorder. The program data is received from the server and the DVR data is received from the digital video recorder The program data and/or the DVR data are displayed on the wireless device. The at least one digital video recorder is controlled by selecting a user-operable function from the program data and/or the DVR data on the wireless device.
