Set-Top Box Video Redirection via Unrendered Data Encoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional web-based video sources for mobile devices lack the variety of content available through broadcast or multicast sources like Internet Protocol Television, resulting in a poor user experience.
Innovation Solution
A method and device that redirect video content from a set-top box to a remote device by decoding and re-encoding unrendered video data for transmission over a wide area network, eliminating the need for external encoding devices and enabling secure, adaptable video delivery to various devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If web-based video sources are used for mobile devices, then device accessibility is improved, but content variety deteriorates
Solution Approach 1:
The set-top box is designed to perform multiple functions: it serves as both a traditional broadcast/multicast video distribution device and a web-based video source for mobile devices. By integrating both functionality, the system provides diverse content (broadcast, multicast, and web-based) through a single device, resolving the contradiction between device accessibility and content variety.
2Adaptability or versatility
If video content is redirected from set-top box to remote device, then content adaptability is improved, but device complexity increases
Solution Approach 1:
The set-top box acts as an intermediary device between the video content source and the remote mobile device. It receives video content from broadcast/multicast sources, decodes it to unrendered video data, re-encodes it in appropriate formats, and transmits it to mobile devices. This intermediary approach enables content adaptability while managing system complexity by centralizing the encoding/decoding functions in the set-top box rather than requiring complex processing at each endpoint.
Data Source
AI summary
A method for redirecting video content includes receiving a video signal at the set-top box and decoding the video signal to produce unrendered video data. The unrendered video data is encoded and provided to the remote device via a wide area network. By encoding unrendered, rather than rendered, video data for transmission to the remote device, the need for an encoding device external to the set-top box is obviated.
