DIGITAL DATA MANAGEMENT USING SHARED MEMORY POOL

摘要

Memory management techniques involve the setting of a memory pool with the amount of shareable memory and the dynamic allocation of a shareable memory to manage multiple sets of sequenced digital data units simultaneously. In an exemplary scenario, a set of sequenced digital data units is a set of time-ordered media samples that form a clip of media content, the technique being characterized in that media samples from two or more clips It is applied when the presentation is possible at the same time. The variable amount of shareable memory is dynamically allocated to prepare the user to present the upcoming media samples to the user. In one possible implementation, the ratio of the average data rate of the individual streams is calculated, and the amount of shareable memory is allocated to the rendering of each stream based on this ratio. The shareable memory, which is then allocated to the rendering of the individual streams, is reserved as needed to prepare the user for presentation of a particular upcoming media sample.;Shareable memory, digital data, dynamic allocation, priority, data rate
