Mobile video delivery
Broadpeak brings its CDN expertise into the world of mobile video delivery.
Broadpeak provides an array of solutions to optimize video delivery to mobile devices. According to the density of the area to cover, the most adapted technology can differ.
Mobile video delivery in low density areas
When the number of concurrent video users in a given location is limited, the most efficient way to deliver content consists in relying on a unicast Content Delivery Network to optimize the backbone for both live and on-demand video distribution.
Deploying Broadpeak edge caching servers and CDN Mediator to allocate the delivery provides the following benefits:
- network optimization by streaming the content from a location nearer the attachment base station, which decreases the load in the backbone
- quality of experience (QoE) improvement by removing points of failure and, in the case of adaptive bitrate streaming, longer presence on higher quality layers
- secured delivery by preventing unauthorized devices to access the content.
Mobile video delivery in high density areas
For Video on Demand content
Broadpeak leverages the eNodeB capability to host its caching servers to store popular content as close as possible to the end-user. This results in increased backbone optimization through the removal of an important amount of traffic that can be managed locally.
For live content
Broadpeak’s BkE200 Transcaster converts a standard unicast television channel into a multicast one and streams it to the eNodeB. This process optimizes the delivery throughout the backhaul network. The multicast stream is then converted back to unicast inside the eNodeB to provide service continuity, short start-up times and limited costs for competitive mobile television services.
Mobile video delivery in very high density areas
Scalability has an impact on QoE. Delivering one high quality video session is easy; delivering the same quality to thousands of collocated users is not so simple. In order to maximize the quality of live television channels in high density areas (such as stadiums), Broadpeak teams up with LTE partners to build a broadcast-based end-to-end delivery solution for mobile users.
LTE and eMBMS standards specify mechanisms to allocate multicast resources only when they are necessary and release them when the event ends. Spectrum is optimized and well shared with other services running on top of the LTE network. As a result, live multiscreen delivery in crowded areas is guaranteed while preserving the regular Internet service.
LTE broadcast technology for this use case relies on a service router to allocate dynamically eMBMS resources.
On top of these scenarios, Broadpeak Mediator server plays the part of a service router by electing the best way to stream a session based on various criteria: network feedback, business model (premium content vs. free content), handsets capabilities, eNodeB capabilities.
Broadpeak’s technologies put you in control and maximize QoE by dynamically implementing the best way to deliver live and VOD content to mobile devices in all situations.
