User-aware Video Optimization
Pacing – Just in Time Optimization
Rather than delivering an entire video as quickly as possible, Pacing – also known as ‘Just-in-time’ delivery – serves each video stream to match the pace at which a person is viewing it. This further opens up bandwidth to enable more concurrent sessions. Although there are various ways of implementing Pacing solutions, the most efficient way is to analyze the content of each video and to optimize each part as necessary: something that Deep Packet Inspection (DPI) can’t do.
- Lossless technique
- Makes sure the video downloads at the speed in which it is viewed
- Saves radio bandwidth
Statistical Caching & Transcoding
Seamless Access analyzes user viewing patterns in real-time to optimize and cache only frequently accessed videos. According to Mobixell ’viewer abandonment‘ studies, about 50 percent of viewers abandon mobile video half way through watching. Seamless Access employs innovative technology to optimize and deliver only the viewed parts of clips. This leads to less resource usage and more bandwidth savings. Operators can choose to optimize those segments only, reducing resource usage whilst still providing bandwidth savings.
User-Controlled Video Optimization (Interactive Toolbar)
Mobile Operators can offer subscribers the Interactive Toolbar to give them control over how they consume mobile video under changing circumstances. Similar to the fuel economy switch on automatic transmissions, the Mobixell Interactive Toolbar lets subscribers make a financial decision when choosing to view video in either high performance or economy mode. For example, when roaming, subscribers can switch to ’economy’ mode to reserve data.
Policy-Based Video Optimization (PCEF)
By implementing the policy and charging rules function (PCRF) in Seamless Access, mobile operators can choose to apply or not to apply optimization techniques for each user according to the rules database. This is something that the Seamless Access policy and charging enforcement function (PCEF) can enforce. For example, an operator might want to set how optimization is applied for video that is streamed to different types of users – for example, prepaid users who are charged by packet, or roaming users who might receive all their video optimized by default and have controls that they can use if they choose to turn off optimization.
