CEVA’s DSP Cores and IP Platforms for Audio, Video, Communications and Storage

A set-top box (STB) is a device that accepts one or more signal sources (including satellite, cable, internet and free-to-air signal), and presents the content of the signal to a Digital Television (DTV) or other display device. The STB may also store the content on a hard drive for later use. In this context, “content” may include – but is not limited to – high-definition video, high-fidelity audio, and interactive pages.

Today's STBs are extremely sophisticated and have to be capable of viewing, recording (storing), playing back (retrieving), and displaying multiple audio/video streams simultaneously. Today's STBs also function as the gateway to broadband and pay TV services, and enable real-time wireless and wired media sharing and internet connectivity. Due to the overwhelming array of software and processing technologies required to be supported in these devices, the optimal solution for the developers of the silicon chips is to handle these functions using state-of-the-art programmable DSP cores.

CEVA is the world's leading licensor of programmable Digital Signal Processor (DSP) cores. To better serve the DTV market, CEVA provides a portfolio of application-specific DSPs offering the highest flexibility and performance, along with associated subsystems, library functions, a comprehensive suite of optimized software codecs, and a complete development environment.
