Mozark通过提高应用程序性能来提高QoE

随着OTT使用的激增和VOD格局的加剧, it has never been more critical to master the art of content delivery. Yet the consistency of user experience in different markets varies wildly, according to Mozark他是一家数字体验平台的印度-法国开发商.

Mozark claims to have a unique means of determining the user experience by measuring performance across applications, 网络, 和设备.

"Monitoring the user experience and pinpointing where issues of latency or buffering lie could spell the difference between success or failure,联合创始人Kartik Raja说. "Yet rather than optimizing both the responsiveness and streaming performance of their app, ott正在做一种权衡. Our mechanism works globally for any streaming media and measures performance and response metrics per country or city. 没有人能解决这个问题."

Mozark是一家成立5年的公司，其设计在美国.年代市场. It started out measuring network performance for national regulators and now works directly with media companies and OTT players.

"We came from a regulator and telco market focussed on network metrics like coverage, 网络质量, and speed and we moved the dial to encompass the quality of experience such as app loads, 交易速度, 视频加载时间, 在回放过程中，缓冲会停止,拉贾说。.

"Most of the original big players were very high-tech companies," he explains. YouTube或Netflix都有自己的SDK, 服务器, 数据中心, 它们自己的纤维, 压缩堆栈, AD引擎. 根据我们的分析, the only OTTs that came close to achieving a consistent experience across the responsiveness of the app and the streaming performance were Netflix, Youtube, 和Hotstar /迪斯尼+."

较小的奥特, however, may not be able to make the same levels of investment in technology and tend to integrate with a lot of third-party software, 多个第三方cdn, 和不同的sdk.

Mozark的联合创始人Chandrasekar Ramamoorthy说, "When you have a service relying on 80% to 90% of integrations from third parties it makes it very difficult for the app owner to understand what is causing issues of QoE. 在某些情况下可能是CDN, 营销SDK加载速度不够快, 或者认证SDK的认证速度不够快. 这些元素不在应用程序所有者的直接控制范围之内."

The company says that for every 100MB of data that is sent by a typical video app, 只有10MB与它自己的后端交换. 其他第三方集成包括OVP, DRM, 媒体管理平台, 营销分析云, 或者是广告云. Understanding the impact that such integrations have on the end-user customer journey performance is deemed critical.

"OTTs with greater control over third-party infrastructure perform better,拉贾说。.

Mozark's testing platform is able to pinpoint which element is causing a problem. It then works with those third-party providers to improve performance so that the overall user journey is improved. It applies a proprietary measure of user experience measure called Application Quality Index (AQI) to streaming performance and responsive of apps on mobile devices as well as DTV boxes and smart TVs. 它的平台是非侵入式的, meaning it does'’t require code changes or security check removals from the app.

Mozark client clients include regulators and telcos in Europe and Asia along with Sony and Indian e-gaming company MPL. 在Hotstar被迪士尼收购之前，它也曾与Hotstar合作过.

"Often, 糟糕的体验被归咎于网络服务提供商, 而是随着5G等新技术的引入, Wi-Fi 6, 和边缘cdn, the onus of QoE is going to be as much on the first and middle mile as in last mile components,拉贾解释道。. "Combine this with the complexity of various device and OS combinations and delivering consistent user experience becomes a challenging task."

Mozark is also able to monitor CDN performance so that app owners can make a more informed decision around which CDN to use in which geography.

“使用最有效的CDN, 这取决于客户的地理分布, 是至关重要的,拉贾说. "A CDN that performs well in India may not necessarily give the same performance in UAE. 即使在国内, we have seen vast differences in the performance of a CDN between various regions based perhaps on a strong or less strong POP presence. For global apps it is very important to know which CDN best serves the app."

添加Ramamoorthy, "The QoE will also change from country to country based on different integrations with third party services, 不同的内容许可法律或设备的变化. 一些国家的iphone普及率可能达到40%. In other places this may be 3% with lots of other lower end devices.

"We provide a very accurate analysis of data consumption as the customer is progressing through the app. If we see a high spike it's likely that the network cannot handle the traffic resulting in buffering or a lag so we can recommend our customers pre-cache some content so the traffic curve is smoothed out."

The company is based out of Singapore and has offices in Paris, Mumbai, and Manilla. 它正在“积极努力”招聘一个团队来扩大在美国的业务.S.
