Streaming media buffering system

Streaming media, such as audio or video files, is sent via the Internet. The media are immediately played on a user's computer. Audio/video data is transmitted from the server more rapidly than it is played out by the user system. The audio/video data in the user buffer accumulates; and interruptions in playback as well as temporary modem delays are avoided.

ELECTRIC COMMUNICATION TECHNIQUE

Packet switching elements-Buffering arrangements-Reactions to storage capacity overflow

TRANSMISSION OF DIGITAL INFORMATION, e.g. TELEGRAPHIC COMMUNICATION 

Selective content distribution, e.g. interactive television or video on demand [VOD] -Client devices specifically adapted for the reception of or interaction with content, e.g. set-top-box [STB]; Operations thereof-Processing of content or additional data, e.g. demultiplexing additional data from a digital video stream; Elementary client operations, e.g. monitoring of home network or synchronising decoder's clock; Client middleware -Processing of video elementary streams, e.g. splicing a video clip retrieved from local storage with an incoming video stream or rendering scenes according to encoded video stream scene graphs-involving video buffer management, e.g. video decoder buffer or video display buffer

PICTORIAL COMMUNICATION, e.g. TELEVISION

Selective content distribution, e.g. interactive television or video on demand [VOD] -Network structure or processes for video distribution between server and client or between remote clients; Control signalling between clients, server and network components; Transmission of management data between server and client ; , e.g. sending from server to client commands for recording incoming content stream; Communication details between server and client -Network physical structure; Signal processing -specially adapted to the downstream path of the transmission network-involving transmission via Internet 

Packet switching elements-Buffering arrangements-using storage descriptor, e.g. read or write pointers

Network arrangements, protocols or services for supporting real-time applications in data packet communication -Responding to QoS

Packet switching elements-Buffering arrangements

Selective content distribution, e.g. interactive television or video on demand [VOD] -Servers specifically adapted for the distribution of content, e.g. VOD servers; Operations thereof-Processing of content or additional data; Elementary server operations; Server middleware-Monitoring of processes or resources, e.g. monitoring of server load, available bandwidth, upstream requests -Monitoring of transmitted content, e.g. distribution time, number of downloads 

Network arrangements, protocols or services for supporting real-time applications in data packet communication -Session management-Session protocols

Network arrangements, protocols or services for supporting real-time applications in data packet communication -Network streaming of media packets-for supporting one-way streaming services, e.g. Internet radio-for unicast

COMPUTING; CALCULATING OR COUNTING

Digital computers in general ; Data processing equipment in general-Combinations of two or more digital computers each having at least an arithmetic unit, a program unit and a register, e.g. for a simultaneous processing of several programs 

ELECTRIC DIGITAL DATA PROCESSING 

Selective content distribution, e.g. interactive television or video on demand [VOD] -Servers specifically adapted for the distribution of content, e.g. VOD servers; Operations thereof-Processing of content or additional data; Elementary server operations; Server middleware-Processing of video elementary streams, e.g. splicing of video streams or manipulating encoded video stream scene graphs-involving management of server-side video buffer

Selective content distribution, e.g. interactive television or video on demand [VOD] -Servers specifically adapted for the distribution of content, e.g. VOD servers; Operations thereof-Processing of content or additional data; Elementary server operations; Server middleware-Interfacing the downstream path of the transmission network, e.g. adapting the transmission rate of a video stream to network bandwidth; Processing of multiplex streams -Controlling the feeding rate to the network, e.g. by controlling the video pump

Selective content distribution, e.g. interactive television or video on demand [VOD] -Network structure or processes for video distribution between server and client or between remote clients; Control signalling between clients, server and network components; Transmission of management data between server and client ; , e.g. sending from server to client commands for recording incoming content stream; Communication details between server and client -Control signaling ; related to video distribution;  between client, server and network components; Network processes for video distribution between server and clients ; or between remote clients; , e.g. transmitting basic layer and enhancement layers over different transmission paths, setting up a peer-to-peer communication via Internet between remote STB's; Communication protocols; Addressing -Control signaling between network components and server or clients; Network processes for video distribution between server and clients, e.g. controlling the quality of the video stream, by dropping packets, protecting content from unauthorised alteration within the network, monitoring of network load, bridging between two different networks, e.g. between IP and wireless -Control signals issued by the network directed to the server or the client-directed to the server-for requesting retransmission, e.g. of data packets lost or corrupted during transmission from server
