TI Extends Codec Interoperability Of eXpressDSP

To further simplify development of digital video products, the eXpressDSP digital media software standard (xDM) adds an algorithm that ensures sweat-free codec implementation and integration for DaVinci technology. xDM is a low-level API for DSP-based software that provides a framework for integrating and exchanging multiple codecs. Video, imaging, speech, and audio can be exchanged between the two platforms with no changes required at the application layer. The xDM API makes it possible to exchange codecs by simplifying codec APIs to encode, decode, and control functions. For applications such as Surveillance IP Networked cameras that support MPEG-4 and H.264, the ability to dynamically exchange codecs improves management of limited network bandwidth and allows use with security DVRs and other equipment. The xDM standard also allows users to create specialized codecs. For example, a camera could support standard MPEG-4 when connected to another vendor’s equipment and employ a specialized but non-compliant version of MPEG-4 that achieves greater compression efficiency when operating with the vendor’s own equipment.
