Qualcomm Technologies has partnered with Sohu.com, the 'Google of China', on a live public demonstration of LTE-TDD broadcast with high efficiency video coding (HEVC) and dynamic adaptive streaming over HTTP (DASH) technologies.

The demo used devices based on Qualcomm reference designs by QTI featuring QTI's Qualcomm Snapdragon 400 processors and integrated Qualcomm Gobi modems, and was supported by QTI's LTE Broadcast solution for the evolved multimedia broadcast multicast service (eMBMS) platform.

LTE Broadcast is designed to allow mobile operators to more efficiently manage their spectrum and network loads by allowing the multicast of high-demand content such as live sporting events, breaking news or software updates, so that multiple users receive the same content simultaneously. It uses standard LTE network architecture and modems.

"We're excited to be supporting the growth and evolution of LTE networks worldwide," said Raj Talluri, senior vice president of product management for QTI. "With LTE Broadcast, operators can better utilise their existing LTE infrastructure to deliver customers an optimised, premium video experience on the latest mobile devices without overloading their networks."

The demo showcases of the many potential implementations for LTE Broadcast, which operators also could use to deliver real-time, location-based or off-peak services, such as pay-per-view events, live broadcast television or important firmware updates.

"This demonstration marks an important milestone in the deployment of LTE Broadcast, which we believe will significantly enhance our customers' ability to view popular, live content directly on their mobile devices," said Zeng, Xiongjie, president of Sohu Mobile Video. "We're excited to be working with QTI to bring this innovative technology to market."

Key 3GPP-standardised features of QTI's LTE Broadcast solution include file delivery over unidirectional transport (FLUTE), DASH, application-level FEC and file delivery with file repair.

LTE Broadcast is commercially available in Korea, and is expected to begin arriving in China and other regions around the world later this year.
