Cisco Visual Quality Experience Rapid Channel Product Details
The Cisco Content Delivery System (CDS) is an integrated system with a network-based architecture that transcends existing video solutions. It incorporates TV streaming for content delivery to digital televisions and set-top boxes (STBs), Internet streaming for content delivery to IP-connected devices, and Cisco Visual Quality Experience (VQE) technology.The Cisco VQE client notifies the designated VQE server of a channel-change request from the viewer. The VQE server responds with a positive or negative acknowledgement. If negative, the VQE client conducts a standard channel-change procedure and does not employ acceleration techniques. If positive, the VQE client engages with the VQE server to conduct a RCC procedure. Video decoder priming information is delivered next, followed by RTP unicast transmission for the target channel. The STB decoder begins video playout soon after initial video packets arrive, resulting in greatly improved channel-change time. Simultaneously, the VQE client performs IGMP leave or join and STB network-buffer-fill operations, concluding the RCC procedure with a transfer to the target channel multicast RTP stream.
