Portable Wireless Device DVR Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable wireless devices lack the capability to record and play back digital video content in a timely manner, limiting users' ability to watch valuable or suspenseful programming while on the go, such as during travel or commuting, due to incompatible broadcast standards and scheduling differences between home and mobile locations.
Innovation Solution
A portable wireless device (PWD) equipped with a transceiver, memory unit, and processing unit that receives and stores video content signals and electronic program guides, allowing users to record and play back content, synchronize with home DVRs, and adjust recording schedules based on location-specific programming information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If DVR capabilities are provided on portable wireless devices, then users can timely watch programming and events while on the go, but the device complexity increases
Solution Approach 1:
The portable wireless device integrates multiple functions including video reception, recording, playback, and synchronization with home DVR systems. The device serves as both a mobile viewing platform and a recording device, enabling users to capture and watch programming anywhere while maintaining compatibility with existing home entertainment systems.
Solution Approach 2:
The system embeds DVR capabilities within the portable wireless device, nesting recording and playback functions inside the mobile platform. The device contains integrated memory for storing recorded content, transceivers for receiving broadcast signals, and processing units for managing recording operations, effectively placing a mini-DVR system within a portable device.
2Reliability
If the portable device records and stores video content locally, then viewing independence from network improves, but the memory capacity requirements increase
Solution Approach 1:
The system records video content in advance during broadcast times and stores it locally in the device's memory. Users can program the device to record specific programs before they need to view them, ensuring that content is ready for independent viewing without requiring continuous network connection. This preliminary recording action enables reliable offline viewing.
3Measurement precision
If the device synchronizes with home DVR programming information, then scheduling accuracy improves, but the data processing complexity increases
Solution Approach 1:
The portable device establishes synchronization with the home DVR system to exchange programming information and scheduling data. The device receives feedback about broadcast schedules, program information, and timing details from the home DVR, using this feedback to accurately schedule recordings and display programming guides. This feedback mechanism ensures scheduling accuracy across both systems.

AI summary
Methods and apparatus for providing digital video recorder services with a portable wireless device (PWD). The PWD includes at least a transceiver, a processing unit and a memory unit. The transceiver receives a video content signal transmitted from a broadcaster of mobile broadcast digital TV, and an electronic program guide (EPG). The processing unit is in communication with the transceiver and the memory unit and the processing unit: stores the TV programming information on the memory unit; displays, responsive to a first user input, the TV programming information; records on the memory unit, responsive to a second user input, a selected video content signal received by the transceiver; and plays back the selected video content signal, responsive to a third user input, from the memory unit.
