Problems solved by technology

[0016] Further, although Release 7PSS (PSSe) standardizes the solution to significantly improve startup and switching times, due to varying channel conditions and content composition (e.g., the number of media streams in the content offering and their bit rates), service The end-user experience during the actual deployment of the
However, QoE metrics for evaluating the effectiveness of PSSe enhancement, especially for user experience during channel / content switching, do not exist so far

Embodiment Construction

[0107] In the following detailed description of the invention, exemplary embodiments of the invention will be described in the context of a Third Generation Partnership Project (3GPP) Packet Switched Streaming Service (PSS) system.

[0108] image 3 is a schematic block diagram of an exemplary embodiment of the system 1 according to the invention. System 1 includes PSS server 2 and PSS client 3 .

[0109] The server 2 includes a processor 20 that controls the overall operation of the server 2 . The processor 20 executes the program codes stored in the processor memory 21. The processor memory 21 can be embodied as a fixed built-in memory, such as a random access memory (RAM) or a read-only memory (ROM), or as a Removable memory such as a memory card or optical storage media. The processor 20 has access to a content storage storing content to be streamed to the client 3 . Wherein, content can be understood as including one or more media streams, such as audio and video stre...

Abstract

This invention relates to methods, computer program products, clients, servers, systems and protocols in the context of reporting a quality of a transmission session according to one or more metrics, inter alia to adapt quality reporting to a switching of content within the transmission session and to allow faster session startup.

Description

technical field [0001] The present invention relates to methods, computer program products, clients, servers, systems and protocols in the context of reporting the quality of a transmission session according to one or more metrics. Background technique [0002] The 3rd Generation Partnership Project (3GPP) Packet Switched Streaming Service (PSS) provides a framework for Internet Protocol (IP) based streaming applications in 3G networks. The document 3GPP TS 26.234V.6.a.0 "Transparent end-to-endPacket-Switch Streaming Service (PSS) Protocols and codes (Release6)" incorporated herein by reference specifies the protocols and codecs for 3GPP PSS . Protocols for control signaling, capability exchange, media transport, rate adaptation and flow protection are specified. [0003] In addition, PSS defines an optional quality of experience (QoE) measurement framework. The QoE metrics framework is a technique for evaluating the end-user experience of media streaming applications. I...
