YouTube在消费电子展上展示vp9编解码的4k视频

Google宣布YouTube将采用VP9编码标准,以替代H.265,这将使高清视频传输所需的数据量减少一半以上。VP9已获得ARM、Intel等主要硬件厂商的支持。

Come CES 2014, Google is going to be one of the companies to have news for us. Google and YouTube will reportedly be showing off 4K video at the event in Las Vegas next week and it will be based on a new royalty-free codec the company has been developing.

GigaOM has reported that the 4K video will be based on VP9, Google’s new codec that aims to replace the H.265 that’s at the heart of multiple 4K implementations. This isn’t the first time Google has attempted to create a royalty-free codec to replace a commercial video format. The VP8 video codec came in 2010 and aimed to be a standard for plugin-free video streaming. Evidently, the plans didn’t work out thanks to lack of hardware support, but Google seems to have plugged that gap now.

Google has announced that most major hardware vendors will be supporting VP9 natively in their products soon. This will allow YouTube to stream HD content up to 4K on devices such as computers, TVs and mobiles. Companies named by Google include chip-makers ARM, Intel, Broadcom and Marvell, and display behemoths such as Samsung, Sharp and Toshiba.

YouTube’s Global Director of Platform Partnerships, Francisco Varela, said that the company did not intend for VP9 to become an “either-or” option for companies. “This certainly isn’t a war of the video codecs,” he said, keeping the possibility that YouTube could support H.265 too. 

The move to VP9, however, should help YouTube bring you HD videos for less than 50 percent of the data currently used. He’s also said that the technology is set to come to PCs and mobile devices first, so if you’re thinking about a TV that supports VP9, you may have to wait till early next year to see the first models being shipped out with it.


读后感:

VP9将会是YouTube即将采用的编码格式,是Google用来抗衡H.265的战略武器。Google甚至还纠结了一批硬件厂商为vp9提供硬件解码器,这对于vp9将是大大的利好。未来安卓手机必然都将自带VP9的硬件编解码器,iPhone要不要跟进就要看了。

内容概要:该论文探讨了一种基于粒子群优化(PSO)的STAR-RIS辅助NOMA无线通信网络优化方法。STAR-RIS作为一种新型可重构智能表面,能同时反射和传输信号,与传统仅能反射的RIS不同。结合NOMA技术,STAR-RIS可以提升覆盖范围、用户容量和频谱效率。针对STAR-RIS元素众多导致获取完整信道状态信息(CSI)开销大的问题,作者提出一种在不依赖完整CSI的情况下,联合优化功率分配、基站波束成形以及STAR-RIS的传输和反射波束成形向量的方法,以最大化总可实现速率并确保每个用户的最低速率要求。仿真结果显示,该方案优于STAR-RIS辅助的OMA系统。 适合人群:具备一定无线通信理论基础、对智能反射面技术和非正交多址接入技术感兴趣的科研人员和工程师。 使用场景及目标:①适用于希望深入了解STAR-RIS与NOMA结合的研究者;②为解决无线通信中频谱资源紧张、提高系统性能提供新的思路和技术手段;③帮助理解PSO算法在无线通信优化问题中的应用。 其他说明:文中提供了详细的Python代码实现,涵盖系统参数设置、信道建模、速率计算、目标函数定义、约束条件设定、主优化函数设计及结果可视化等环节,便于读者理解和复现实验结果。此外,文章还对比了PSO与其他优化算法(如DDPG)的区别,强调了PSO在不需要显式CSI估计方面的优势。
