Audio, voice, connectivity earmarked for UHDTV

802.11ac push
Meanwhile, higher bandwidth connections such as 802.11ac designed to bring HD video to the home, are generating high expectations among service providers, system companies and chip suppliers.

Broadcom CTO Samueli said this is "the first time carriers are convinced that they can deliver reliable HDTV programming throughout the home." In this scenario, carrier-grade video content comes to a media gateway that distribute it to set tops, notebook computers and smartphones.

CEVA's CEO Gideon Wertheizer stressed that 802.11ac isn't just for home networking. It's also becoming a critical requirement for small cells in cellular networks. The 802.11ac spec will be an important feature for small cells, whose chips are designed by companies like Mindspeed and Cavium.

"Operators want to offload traffic by using Wi-Fi," observed Wertheizer. CEVA, working with wireless specialist Antcor, is offering software-based multi-standard Wi-Fi solution on its CEVA-XC4000. The two companies are enabling 802.11ac in Wi-Fi access points, routers, gateways and small cells.

Triggering a proliferation of natural user interface devices is the availability of OpenCV, a standard library of programming functions for computer vision processing.

CEVA is leveraging the ready-to-use library, optimizing it with CEVA's C-level compiler for the CEVA-MM3101 imaging and vision platform. While CEVA is already working with eyeSight to enable gesture control that supports multiple hand gestures, palm detection and tracking on its MM3101 platform, the company also announced during CES a partnership with iOnRoad to enable an advanced driver assistance system on the MM3101.

Of course, CEVA isn't alone leveraging OpenCV. Qualcomm is porting OpenCV to ARM's Cortex A9-based processor. CEVA's Briman, however, claimed that CEVA's MM3101 platform can run iOnRoad software at 10 times less power consumption, compared to Qualcomm's solution.
