Across the field of multiple electronic applications, STMicroelectronics (ST) and the world's leading communication system, digital media and service research and development center Fraunhofer Heinrich (Fraunhofer Heinrich) Hertz InsTItute (HHI) jointly launched the industry's first 3D video receiver based on the new MPEG-DASH standard, dynamic and adaptive HTTP streaming media. This development is part of the European Union ’s Content Recognition Intelligent Search and Streaming (COAST) project.
HTTP streaming technology can transmit high-quality video signals to Internet-connected TVs, set-top boxes and mobile terminal media playback devices via the Internet. The dynamic adaptive HTTP (DASH) streaming media standard recently announced by the 3GPP and MPEG working groups aims to simplify the deployment process of broadband video streams on different network infrastructures and terminal devices, introducing an open standardized solution in the industry to replace the market Many HTTP streaming media protocols that are exclusive to certain companies. DASH specifies the format used for content preparation and fast and efficient content adaptation tools. The standard supports stunt mode, multilingual subtitles and soundtracks, advertisement insertion and digital rights management technology to protect content, and is compatible with standard network servers and video buffering technologies.
This software video receiver based on ST-HHI DASH standard adopts sophisticated and advanced algorithms, according to the actual situation of the network, terminal equipment functions and user preferences to customize settings, automatically select the stream transmission rate, video resolution and file format to ensure The video stream is continuously transmitted to the player, bringing the best visual experience to consumers. By automatically adjusting the video streaming rate, the software can automatically correct the impact of bandwidth fluctuations on image quality, and can automatically select the video file format according to the type of terminal device, allowing consumers to watch 3D content on standard 2D display devices.
The ST-HHI 3D adaptive streaming media environment includes a video server, a personal computer equipped with a 3D display, and a thin client terminal device with a 2D display. The 3D video stream is generated on a remote server and transmitted to two terminal devices through the IP protocol. At the same time, the 3D video stream is automatically converted into 2D content on the thin client terminal device. The product prototype implements DASH technology through the GStreamer development environment. GStreamer is a popular multimedia development framework for personal computers and embedded platforms, which supports multiple media formats and streaming protocols.
Amedeo Zuccaro, Director of Security and Multimedia System R & D Center of STMicroelectronics Advanced System Technology Department, said: "DASH can efficiently and easily transfer video-on-demand or live video streams to any networked equipment through the existing Internet infrastructure without any special Configuration. Through cooperation with HHI, we became the first chip manufacturer to integrate DASH adaptive video streaming technology inside the chip. "
Dr. Thomas Schierl, Director of Multimedia Communication Products at the Fraunhofer Heinrich Hertz Institute in Germany, said: "From laboratory and trial environment to entering the market, everyone can now enjoy 3D video technology. We are very pleased to be able to work with ST Semiconductor is cooperating in the development of next-generation media devices to jointly welcome the advent of the era of 3D stereo and multi-view video content.

Today let`s talk about touch screen laptop. Sometimes people take Yoga Laptop or 2 In 1 Laptop or 360 Laptop as foldable touch screen laptop. Cause the later ones usually with touch screen function. The difference is that touch screen laptop specials can`t be flipped up to 360 degree, usually 180 degree. Do you think which kind of person love 2 in 1 touch screen laptop more? Business people is the right answer, cause they care more performance, touch screen function, 180 rotating, which are the very important points for businessman, especially teaching in person, do presentation, etc.
Do you think what other business laptop businessman love also except touch screen laptop under 20000? 14 inch 11th Laptop and 15.6inch 11th or 10th Laptop should be the top levels.
