Digital Televisions

CEVA’s DSP Cores for Communication, Audio and Video Encoding, Decoding, and Post-Processing

Today’s Digital Televisions (DTVs) are no longer required only to display high-definition (HD) video signals – they also have to satisfy the users’ demand for the highest fidelity audio/video (A/V) experience, user interactivity, and internet connectivity. Increasing interaction with the Internet requires digital TVs to support a vast variety of formats for audio and video standards, including H.264, MVC, S3D, MPEG2, VP8, AAC, AC-3 and Dolby Digital Plus. In order to further differentiate their products, vendors are constantly adding unique post-processing functions to their TV sets, both audio (e.g. SRS and Dolby Volume) and video (e.g. scaling and de-interlacing). Other growing requirements for DTVs are the support of high quality video conferencing and human machine interface (HMI) applications such as gesture and voice recognition for controlling the Smart TV.

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.

CEVA application-specific offerings for DTVs are as follows:

High-Definition Audio and Voice Processing: CEVA-HD-Audio and CEVA-TeakLite-4

• Supports complete DTV audio uses-cases on a single core, leaving ample headroom for heavy post-processing functions
