Dynamic Video Playlist Navigation for On-Demand Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current on-demand services in cable networks provide limited and slow navigation through selection menus, lacking media richness and complexity, which hampers user experience due to the absence of engaging graphics and descriptive information.
Innovation Solution
The system provides media-rich video segments with selection links superimposed over them, using navigation catalogs and playlists to enable dynamic and descriptive selection menus, allowing users to navigate on-demand services with video, audio, and animated text, enhancing user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If selection menus are provided using traditional carousel-based file delivery, then system complexity is reduced and ease of manufacture is improved, but navigation speed is slow and media richness is limited
Solution Approach 1:
The system dynamically delivers video segments based on user navigation actions. Instead of static menus, the system provides different video segments (backgrounds, transitions, content) based on the user's current position and selections in the menu hierarchy, enabling fast navigation with media-rich content.
Solution Approach 2:
Video segments are pre-encoded and stored in the system ready for immediate delivery. When a user navigates to a menu screen, the corresponding video segment is already prepared and can be delivered instantly, eliminating the need for real-time encoding or complex file assembly during navigation.
2Loss of information
If media-rich video segments with graphics and animation are provided, then user experience and media richness are improved, but data transmission requirements and system complexity increase
Solution Approach 1:
The navigation interface is segmented into separate video segments (background segments, transition segments, content segments) that can be independently delivered and assembled. Each segment contains specific visual elements, allowing the system to provide rich media content while maintaining manageable system complexity through modular delivery.
Solution Approach 2:
The system uses an intermediary mechanism (the video segment delivery system) that translates complex media-rich content requirements into standardized segment deliveries. This intermediary layer handles the complexity of media delivery, allowing the user interface to remain simple while supporting rich graphics, animation, and descriptive information.
3Adaptability or versatility
If unique video segments are provided for each service and selection menu, then adaptability and user engagement are improved, but data storage requirements and system complexity increase
Solution Approach 1:
The video segment delivery system is designed to be universal and service-agnostic. The same infrastructure delivers video segments for multiple services (HBO, Showtime, ESPN, etc.) and multiple menu types (service selection, program selection, episode selection). This universal system reduces overall complexity while maintaining service-specific customization through content rather than structural differences.
Data Source
AI summary
In one embodiment, a method of operating a communications system is disclosed comprising receiving a request for establishment of a session from a terminal, establishing the session with the terminal, and providing at least one navigation video segment to the terminal, via the session. The communications system may be a source of programming, such as a cable system, and the terminal may be a set-top terminal coupled to a display device. The navigation video segment may be used by the terminal to create selection menus to be displayed for user navigation. The video segments may be rich media video segments. A playlist may be generated comprising an indexed listing of a plurality of available video segments. The playlist may facilitate retrieval of video segments requested by a terminal. Communications systems, terminals and methods of operating a terminal are disclosed, as well.
