FLO Forum finalizes FLO receiver application programming interface spec
March 4, 2008
The FLO Forum has completed the FLO receiver application programming interface (API) specification, along with the mobile TV content and services specification.
The FLO receiver API specification, designed to facilitate multivendor interoperability, defines the interfaces between the Media Access Control (MAC) layer and the control and stream layers in the FLO receiver protocol stack. It represents the second contribution to the OpenFLO initiative, and the first at the device platform level, following the completion of the Open Conditional Access Framework in November 2007.
Any FLO receiver stack that adheres to the specification will be interoperable with any FLO ASIC specific software, giving handset manufacturers access to a wider choice of suppliers when developing new FLO-applicable devices.
The mobile TV content and services specification addresses the demands of content providers of the FLO mobile broadcast system, defining guidelines for screen resolutions, frame rate, color quality, source and output formats, channel switching time, captioning, offline viewing, number of channels supported and viewer feedback and rating capabilities.
