McObject’s eXtremeDB Fusion Database Chosen for DIRECTV Set-Top Boxes

McObject® announced that DIRECTV, the leading U.S. satellite television service provider, will integrate the eXtremeDB™ Fusion embedded database system into its set-top box software, leveraging eXtremeDB Fusion’s hybrid in-memory/on-disk data storage to significantly reduce development time across a range of hard disk-based and disk-less boxes, and to improve processor utilization.

eXtremeDB Fusion will lend its strengths of high performance and efficient, small footprint data management. The set-top box software stores programming information, including program descriptions, schedules, ratings, user configuration information such as favorite channel lists, and multimedia content.

As a hybrid embedded database, eXtremeDB Fusion combines on-disk and all-in-memory record storage. A simple schema notation controls which records are to be saved to disk, and which are to be managed entirely in memory, without the I/O, caching and other processes inherent in disk storage.

This capability enables DIRECTV to develop a unified software platform and deploy it across a product line containing some set-top boxes with hard disks—to support digital video recording (DVR)—and others without hard disks.

“In consumer electronics, it is common for a manufacturer to develop one version of a product that incorporates disk storage, and another version that stores data in memory,” Steve Graves, McObject CEO and co-founder, said. “In this situation, eXtremeDB Fusion eliminates the need to use two different database systems, thereby avoiding significant coding, testing and QA tasks. In this sense, eXtremeDB Fusion’s combined in-memory, on-disk storage provides the best of both worlds,” he said.

Graves cited eXtremeDB Fusion’s caching policy — the application logic that determines which database resources should be held in memory, and for how long — as instrumental in enabling efficient use of the CPU in disk-based smart consumer devices. “Database caching and disk I/O can be a significant drain on the CPU, but eXtremeDB Fusion’s efficiency in this area gets the most out of available resources. With McObject’s database, CPU cycles can be directed toward CPU-intensive tasks, such as media playing and recording, to produce the best possible multimedia consumer device performance,” Graves said.
