McObject's Embedded Database Expands Marketing Reach of Loewe Opta's Digital Televisions
German consumer electronics manufacturer Loewe Opta has integrated McObject's eXtremeDB embedded database into electronic programming guide embedded software in new digital televisions. Among other benefits, eXtremeDB's custom collations feature enables Loewe Opta's TVs to offer search features that support character sets of all European languages.

McObject®, developer of the eXtremeDB® Fusion embedded database system, announced that German consumer electronics manufacturer Loewe Opta has released new digital television models with electronic programming guide (EPG) software based on eXtremeDB Fusion. By integrating McObject’s commercial, off-the-shelf (COTS) database system into its new Individual SL and Compose SL TVs, Loewe Opta both reduced time-to-market for the products and ensured they would meet user demands for the fastest possible access to schedules, programs and other data.
eXtremeDB Fusion also delivered a key marketing advantage for Loewe Opta by enabling the company to offer the Individual SL and Compose SL models to high-end consumers in widely divergent native language markets. A “custom collations” feature, added in eXtremeDB Fusion 4.1, provides “hooks” for developers to provide a desired character sorting sequence (collation) for data stored as text, including collation that supports a particular language or combination of languages. In comparison, most embedded databases provide a single, fixed collation.
With this feature, the same programming guide software in Loewe Opta televisions can be used across all European sub-markets, with languages and characters as different as English, Spanish, Russian and Greek. “Software re-usability is a holy grail for manufacturers because it can dramatically lower development costs. From the start, eXtremeDB has ported easily between different hardware, but eXtremeDB 4.1 adds a twist by enabling developers to build in text sort and search features that are portable between different written/spoken languages,” McObject CEO Steve Graves said.
“This new kind of portability will grow in importance with the globalization of consumer product markets. McObject is glad eXtremeDB Fusion’s custom collations feature is helping Loewe Opta’s digital televisions succeed,” Graves said.
eXtremeDB Fusion’s speed and small footprint were also critical factors in Loewe Opta’s decision to use it, said Rudi Latuske, manager of McObject GmbH, McObject’s Munich-based subsidiary. eXtremeDB Fusion delivers high performance via a streamlined database architecture and the ability to manage data in memory, with direct access. The product’s tiny code size of approximately 150K, and its equally frugal CPU demands, reduce each television’s hardware requirements, resulting in lower per-unit manufacturing costs.
These strengths and other developer- and manufacturer-friendly features have made McObject’s eXtremeDB the leading embedded database system for digital TV electronic programming guides. Whether EPG software resides in a set-top box or in the television itself, it increasingly benefits from an off-the-shelf database system to manage growing volumes of programming data and support advanced EPG features.
But "database system" is a broad product category, and while some DBMSs specialize in addressing business or packaged software needs, only eXtremeDB was designed from scratch for set-top box programming guides and other real-time embedded systems.
For example, among embedded database systems, eXtremeDB supports the widest range of data types. Among others, it offers variable length strings, a data type that allows physical storage space to expand or contract, depending on the size of the stored data. Within an electronic programming guide, a show description is ideally stored as a variable length string. It can be nonexistent for the nightly news (which has no description) or can be lengthy for the synopsis of the Friday Night Movie.
Many other embedded database products lack support for variable length strings. The result is that EPG designs must allocate resources based on the "worst case" or maximum possible program description length. This boosts set-top box memory and storage requirements, increasing costs for the manufacturer--and ultimately for the consumer.
Hybrid database storage is another key advantage. While most DBMSs store data either in memory or on-disk, McObject's eXtremeDB Fusion permits developers to combine both kinds of storage in the same database instance. This can be a boon when set-top box or digital TV product families include some units with hard drives, and others that are disk-less. By enabling both kinds of storage, eXtremeDB Fusion permits the same EPG database software to be used across all units, sparing the expense, learning curve and support costs of incorporating multiple embedded database products.
Application programming interfaces are another area where eXtremeDB holds an edge for EPGs. eXtremeDB offers a native programming interface that is fast and intuitive to learn. It is also type-safe, catching data-typing errors to eliminate a common source of run-time bugs. But eXtremeDB also provides multiple SQL APIs, including ODBC. As a SQL embedded database, eXtremeDB leverages developers' familiarity with this universal interface. ODBC permits seamless interoperation with a wide range of external systems, which is a necessity in an age of digital convergence.
McObject also provides source code for eXtremeDB, which gives developers the flexibility to extend features and lends an in-depth understanding of the database engine within an application.
