Digital Video Jukebox Storage and Playback System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audiovisual jukebox systems are bulky, require frequent maintenance, and lack the ability to simultaneously play music, videos, and advertisements in various formats without needing physical drive replacements or constant server connections.
Innovation Solution
A system comprising a central processor, storage device, and copy-control device that allows for the simultaneous playback of music, videos, and advertisements, with the ability to update content independently and verify licensing status, including add-on devices like DJ and karaoke modules, and 'daughter' jukeboxes for multiple locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical CD libraries and mechanical players are used, then faithful and good quality reproduction is achieved, but the system becomes large, bulky, and requires frequent maintenance
Solution Approach 1:
The patent replaces mechanical CD players and physical disk libraries with a digital storage system using hard drives and solid-state storage. The mechanical components that required frequent maintenance (laser readers, rotating disks, tray mechanisms) are substituted with electronic data access systems that have no moving parts, thereby eliminating maintenance requirements while maintaining reproduction quality.
Solution Approach 2:
The patent creates digital copies of music and video content stored on hard drives instead of requiring physical CD media. Multiple copies can be stored in compact digital form, allowing the system to hold extensive libraries without the physical bulk of CD cases and disks, thus reducing system size while preserving content availability.
2Quantity of substance
If physical CD libraries are used, then content storage is achieved, but the system becomes large and bulky
Solution Approach 1:
The patent stores digital copies of music and video content on hard drives with capacities measured in gigabytes and terabytes. A single hard drive can store thousands of songs and numerous video files, equivalent to thousands of physical CDs, in a space occupying only a fraction of the volume of a physical library, thus achieving high storage capacity in compact form.
Solution Approach 2:
The patent changes the storage medium from optical disks (CDs) with fixed physical capacity to magnetic and solid-state storage with exponentially larger capacities. This parameter change in storage density allows the system to hold vastly more content without proportionally increasing system size, resolving the contradiction between storage capacity and physical volume.
3Adaptability or versatility
If all pieces are kept on the library, then complete content availability is maintained, but the system requires frequent maintenance and cannot eliminate unused pieces
Solution Approach 1:
The patent implements digital copying where content can be easily duplicated, deleted, or updated in the digital storage system. Unused or obsolete tracks can be permanently removed from the hard drive without affecting the physical integrity of the storage medium, allowing the library to be dynamically optimized for actual usage patterns while maintaining reliability.
Solution Approach 2:
The patent creates a dynamic content management system where the digital library can be easily modified - tracks can be added, removed, or replaced through software operations. This dynamic capability allows the system to adapt to changing usage patterns and eliminate unused content without mechanical intervention, reducing maintenance needs while preserving content availability for actively used material.
4Productivity
If broadband server connection is used for content delivery, then content transmission is achieved, but the system requires constant connection and complex communication protocols
Solution Approach 1:
The patent implements preliminary action by pre-downloading and storing content locally on the jukebox's hard drive before it is needed for playback. This eliminates the requirement for constant broadband connection during operation, as the content is already available locally. The system only requires intermittent connection for initial content acquisition and updates, significantly reducing operational complexity.
Solution Approach 2:
The patent introduces local digital storage as an intermediary between the broadband server and the playback system. Instead of requiring direct real-time communication between the jukebox and server during playback, the local hard drive acts as a buffer that stores content locally, decoupling the playback function from the network connection and simplifying the overall system architecture.

AI summary
A digital jukebox (14) allows for playback of a first offering and a second offering. The contents of each offering are individually licensed for public performance at a particular location where the jukebox is found. The jukebox (14) displays advertisements that are selected in response to user interaction with the jukebox or a number of other factors. The jukebox (14) features a screen (18 and 20) that allows user to interact with the jukebox to select offerings, but also to respond to advertising. Jukebox can function in cooperation with a server (12), but in the alternate, can function as an independent and stand-alone device when connection (16) to server (12) is not available.
