TI Extends Codec Interoperability

Texas Instruments (TI) introduced its "eXpressDSP" Digital Media Software Standard (xDM), a low-level application programming interface (API) for DSP-based software that provides a framework for integrating and exchanging multiple codecs within an application.

xDM is an extension of TI's widely deployed eXpressDSP Algorithm Interoperability Standard (xDAIS), and makes it possible to exchange codecs by simplifying codec APIs to encode, decode, and control functions. Simple exchange of algorithms is an essential characteristic for many applications.

TI said that for fixed applications, the ability to swap out different algorithms without having to rewrite application code enables developers to leverage the same hardware platform across a wide range of applications. For emerging applications, such as Surveillance IP Networked cameras that can support both MPEG-4 and H.264, the ability to dynamically exchange codecs improves management of limited network bandwidth and allows flexible use with security DVRs and other equipment.
