Memory management of digital audio data
View Patent ↗A system, method and computer-readable code for the management of digital media on a device with memory and storage restrictions. As with any device, memory and storage is limited. With the ultimate goal of providing a user with a hands-off literary experience involving multiple media types, it is necessary to automate the clean-up of unneeded content that has previously been transferred to the device. Utilizing bookmark information that describes various positions in one or more media streams, time information that describes the various media streams and related content used to integrate various types of content for each media stream, content and storage can be managed such that the user never has to interact directly with stored content beyond the controls provided with a basic media player. The user still experiences a completely automated and seamless literary experience regardless of the number of open media streams, bookmarks and various related content the user has. The result is a fully automated context aware memory and content manager.
