Candidate standard allows software upgrades for DTV receivers

The ATSC has published a new candidate standard that provides specifications for downloading software to terminal devices using an MPEG-2 transport stream.

The Software Download Data Service Candidate Standard (CS/97) may be used to update or upgrade firmware, operating system software, device driver software, native application software, middleware, and other types of software that reside in devices such as consumer DTV receivers.

The Software Download candidate standard will allow receiver manufacturers to perform dynamic upgrades of their products in the field.

CS/97 specifies the announcement, signaling and encapsulation mechanisms for the delivery of a download data service in the ATSC transport. It allows the specific details of the software download payload to be defined by each manufacturer.
