Embodiment Construction

[0080] The present invention removes ambiguity in the timing of reporting quality feedback values ​​in streaming services by clearly and uniformly proposing to specify a timestamp metric (timestamp semantics) for each defined quality metric. For two continuous multimedia applications such as simultaneous video and audio transfers, and for real-time, low-latency applications such as conversational applications. The timestamp metric is based on the relative media playback time, which may for example be Normal Play Time (NPT), which is available if a real-time streaming protocol is used, or the timestamp metric may be provided from RTP and included in The real-time transport protocol (RTP) timestamp in each RTP header is derived, or the timestamp metric can be derived from the time base or timestamp of the real-time transport control protocol RTCP or the session initiation protocol SIP.

[0081] RTCP is based on the periodic transmission of control packets to all participants in ...

Abstract

The invention particularly relates to a method for quality feedback in stream transmission service. At least one media stream is subjected to stream transmission to a client side; a quality feedback value is determined according to at least one quality metric; and determining a timestamp relevant to the quality feedback value according to at least one timestamp metric, wherein the corresponding timestamp metric is defined for each at least one quality metric, and the corresponding timestamp metric is defined, each at least one timestamp metric is based on media playing time corresponding to the at least one media stream, and the quality feedback value and the relevant timestamp are reported to the server. Preferably, the relevant media playing time is exported from real-time transmission protocol timestamp, the normal playing time provided by the real-time stream transmission protocol, the timestamp of real-time transmission control protocol or the timestamp of an initial session protocol.

Description

[0001] This application is a divisional application of the patent application 200480041534.3 with a filing date of February 13, 2004. technical field [0002] The present invention relates to a method, a computer program, a computer program product, a system, a client, a server and a protocol for quality feedback in a streaming service, wherein at least one media stream is streamed to the client. Background technique [0003] On the one hand, streaming refers to the ability of an application resident in the client to play in a continuous fashion synchronized media streams, such as voice, audio and video streams, while those streams are being played over the data network to the client. Streaming, on the other hand, also refers to real-time, low-latency applications such as conversational applications. [0004] Applications that can be created on top of streaming services can be divided into on-demand and live information delivery applications. Examples of the first category ...
