Retailer Best Buy has conducted internal tests showing products certified under the guidelines of the Digital Living Network Alliance are not fully interoperable. The retail giant is considering withdrawing from DLNA, and word of the tests is beginning to spook others about adopting the group’s guidelines.
The news comes at a time when DLNA is seeing a significant ramp in systems getting certified to wear its logo. The alliance was formed in 2003 to set guidelines to assure interoperability among a broad range of networked consumer, computer and communications systems.
Executives from DLNA said they were not aware of the Best Buy tests. However, they acknowledged shortcomings in interoperability of certified products, and said they have programs in place to address some outstanding issues.
