METHOD FOR EDITING MEDIA CONTENTS IN A NETWORK ENVIRONMENT AND DEVICE FOR CACHE STORAGE OF MEDIA DATA

摘要

In the domain of studio engineering (film studio, television studio, communication studio), streaming-server-based computer networks have increasingly made an entrance". The .streaming servers (RSA, R$B, RSC) are used to archive the original data from the recorded articles and to make them available to the various editing computers (EA, EB) via the connected highspeed network ((JJE) . This approach has the advantage of a much greater level of availability to the original data, etc. Another advantage is that new compositions based on editing lists can be created which can then be processed in the editing device (EA, EB), and the composition"s data can be requested and delivered from the server devices (RSA, RSB, RSC) in real time without this requiring fully "rendered" articles to be created and stored. When editing a new article, sections of the original data are loaded into the editing computer. Cuts are usually edited successively with coarse and fine cuts, which means that data sections frequently need to be reloaded. To relieve the network (GE) of such frequent loading operations, the invention proposes arranging a cache store (CS) in the data path between the server devices {RSA, RSB, RSC) and the editing device(3) (EA, EB), which cache store holds important parts of the loaded data sections ready. As particularly important parts, the data in an area around the start and end of a loaded data section are reloaded into the cache store {CS), because these areas are checked particularly frequently during cut editing.
