Cloud DVR Integral Program Content Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cloud-based digital video recorders (DVRs) face limitations in recording television shows that extend beyond scheduled broadcast times due to fixed recording increments, leading to potential missed content or wastage of recording time, especially for events like sporting events or news stories that may run longer than expected.
Innovation Solution
The implementation of an integral program content distribution system that allows users to record program content based on apparent broadcast times, determined using electronic program guide data and additional content information sources, enabling seamless recording of media programs or excerpts regardless of scheduled broadcast times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed recording increments are used for television shows, then the recording process is simplified and standardized, but shows that extend beyond scheduled broadcast times may have content missed or recording time is wasted
Solution Approach 1:
The system dynamically adjusts the recording end time based on detected program transitions in the media stream. Instead of using fixed predetermined increments, the recording duration adapts to the actual content structure, extending or shortening the recording window to capture complete programs while avoiding waste of recording resources.
2Reliability
If extended recording time is set to capture complete shows, then content completeness is improved, but recording time wastage increases when shows end earlier than expected
Solution Approach 1:
The system continuously monitors the media stream for program transition indicators (such as title cards, scene changes, or metadata markers) and uses this feedback to dynamically adjust the recording end time. This feedback mechanism allows the system to capture complete programs when they run longer than scheduled while stopping recording promptly when programs end early, eliminating both content loss and time wastage.
3Measurement precision
If manual intervention is required to adjust recording times, then recording precision can be improved, but user convenience and automation decrease
Solution Approach 1:
The system automatically detects program transitions within the media stream and self-adjusts the recording parameters without requiring user intervention. The automated detection of program boundaries and dynamic adjustment of recording windows provides both high precision and full automation, eliminating the need for manual time adjustments while maintaining accurate program capture.
4Device complexity
If cloud-based DVR systems record based on scheduled broadcast times, then system complexity is reduced, but adaptability to actual broadcast variations decreases
Solution Approach 1:
The system performs preliminary detection of program transition indicators within the media stream to determine actual program boundaries before finalizing recording parameters. This preliminary action allows the system to adapt to broadcast time variations while maintaining simple operation, as the adaptation is automatically performed based on detected content structure rather than requiring complex user input or system reconfiguration.

AI summary
This document describes techniques using, and devices embodying, integral program content distribution. These techniques and devices enable a request for program content to be received from an end-user device. In response to the request, an integral version of the requested program content is determined using an indication of a program content transition that corresponds to an apparent broadcast time of the requested program content. The program content can be transmitted to the end-user device as part of a cloud-based digital video recorder (DVR) system.
