Architecture for Multi-Client Multi-Channel Compressed Video Streaming
نویسندگان
چکیده
In this paper we describe an architecture for a multi-client, multi-channel video streaming server targeted at the security market. For each connected client, the best selection of available compressed video streams per channel is made, optimizing the perceived quality of the video channels requested by the client. We propose techniques to scale the bitrate per video stream and introduce a scheduling scheme to select the best video streams for a given set of channels and bandwidth constraints.

متن کاملMultiple View Video Streaming and 3d Scene Reconstruction for Traffic Surveillance
We present a 3D modeling system for traffic surveillance applications. The application contains several cameras positioned around a traffic scene. The video signals are compressed and streamed to a central client. At the central client a scene reconstruction is carried out, using all 2D camera views utilizing 3D camera calibration information. To combine all views into a 3D model, moving object...
متن کاملThe Feedback Based Mechanism for Video Streaming Over Multipath Ad Hoc Networks
Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...
متن کاملLearning Binary Residual Representations for Domain-specific Video Streaming
We study domain-specific video streaming. Specifically, we target a streaming setting where the videos to be streamed from a server to a client are all in the same domain and they have to be compressed to a small size for low-latency transmission. Several popular video streaming services, such as the video game streaming services of GeForce Now and Twitch, fall in this category. While conventio...
متن کاملMPEG-4 broadcast: a client/server framework for multi-service streaming using push channels
This paper presents the architecture and implementation of a multi-service streaming system for broadcast of MPEG4 elementary streams. The proposed system promotes the use of the push channel model for information distribution [1]. The system architecture accommodates two main layers for broadcast service management and media delivery. The broadcast service management layer uses the publisher-s...
