DRM Consortium members Inntot Technologies (based in India) and STMicroelectronics (global) are strengthening their collaboration on automotive digital radio. On October 29, Inntot announced that it has become an official STMicroelectronics Authorized Partner, combining ST’s automotive radio tuners with Inntot’s software-defined radio technology to support DRM, DAB/DAB+ and China Digital Radio (CDR).
According to the announcement, the combined solution enables vehicle manufacturers and automotive suppliers to integrate multiple digital radio standards into infotainment systems without dedicated hardware decoders. The software-based approach aims to reduce costs, board space and power consumption, while allowing manufacturers to adapt receiver platforms to different markets through software configuration.
Inntot reports that deployments of its DRM software-defined radio technology exceeded 2.6 million vehicles as of September 2026. Its established presence in India’s automotive market provides a strong basis for this collaboration, which targets vehicle manufacturers and automotive suppliers worldwide.
From the DRM Consortium’s perspective, this development illustrates the opportunities that an open standard such as DRM can create for domestic technology companies. Experience and scale gained in a home market can provide a foundation for international partnerships, technology exports and software expansion.
The Consortium also highlights the wider relevance of multi-standard reception in countries where complementary digital radio standards serve different broadcasting needs. China combines DRM and CDR, while Indonesia has adopted DRM for the AM bands, VHF Band II – the FM band – and the lower part of VHF Band III, alongside DAB+ in the upper part of Band III. In Africa, the African Telecommunications Union’s strategy for Digital Sound Broadcasting (DSB) recommends DRM and DAB+ according to frequency bands and coverage requirements.
Receivers supporting these complementary standards can help listeners access the services available in their country through a single device. Such multiple-standard receivers have been already announced by the DRM Consortium. For manufacturers, a common receiver platform supporting several standards offers greater flexibility across markets.
The Inntot–STMicroelectronics collaboration adds to the growing range of DRM-capable and multi-standard receiver technologies developed by DRM Consortium members, broadening the options available to the automotive industry and supporting wider access to digital radio.
The companies report that their joint solutions are available for evaluation, sampling and integration into automotive infotainment programmes.
