VIDEO CENTRIC NETWORK – PUBLISH/SUBSCRIBE (VCN-PS)

CEDEO develops major VCN-PS demonstration using
MXM and CONVERGENCE

Video Centric Network (VCN) is a new network paradigm where storage, transfer and retrieval of information is not based on location but on identifiers. In VCN Publication of information and Subscription to (Pub/Sub) information are two basic and complementary functions. The FP7 CONVERGENCE project has developed, implemented and tested the specification of Pub/Sub based on the MXM architecture. CEDEO has now implemented Pub/Sub and storage/Retrieval of video using the DASH standard. The demo implementation is based on the model and walkthrough below.

Legenda

• SEGMENTER_SERVICE: segments video according to DASH
• CREATOR: creates R-VDI, P-VDI and R-VDI
• CONSUMER: retrieves R-VDI and plays video
• Peer: the combination of CREATOR, CONSUMER and P-VDI/R-VDI match
• DASH Segmenter: performs the actual segmentation
• GST plugin: an extension to GStreamer
• MXM: an instance of the MPEG Extensible Middleware
• CoNet: an MXM Engine that interfaces with VCN
• Overlay: the functionality as defined by CONVERGENCE
• VLC MF: an MXM Media Framework Engine instance based on VLC
• PROXY: an HTTP PROXY
• CONET Node: an instance of the VCN communication stack, running on a node of the physical network
• CONET servlet: an interface that allows users of the VCN to inject and fetch from remote CONET Repositories
• CONET Repository: a storage of the VCN for data segments and their associated identifier, local to a CONET node
