Problems solved by technology

[0010] However, the implementation of this solution for configuring the buffering time (hereinafter also sometimes referred to as "bufferisation") poses certain difficulties
[0011] Therefore, the first disadvantage of this solution is that it leads to increased traffic
This increased traffic will interfere with network access and lead to non-negligible cost increases

Embodiment Construction

[0044] figure 1 Shown is an architecture 100 using a device 108 according to the invention. In the example shown, device 108 is a digital television decoder.

[0045] Architecture 100 further includes:

[0046] - television receiver 119, telephone 106 and microcomputer 107,

[0047] - modem 105,

[0048] - a network 104 of Internet type,

[0049] - A remote source 101 of audiovisual data, such as a remote server.

[0050] The modem 105 is a "3-in-1" modem of the ADSL ("Asymmetric Digital Subscriber Line") type, which provides the user with access to three services, namely TV or Video on Demand, VoD, Telephone communication via telephone 106 and Internet via microcomputer 107 .

[0051] The server 101 includes an encoder 102 and an encapsulation device 103 .

[0052] Regardless of VoD or TV signals, the local audio and video signal S 1 , wherein the signal undergoes MPEG-2 type compression and encoding in the encoder 102 to produce an MPEG-2 signal S 2 . Although this...

Abstract

The present invention relates to a device (108) for the continuous reception of audio and / or video data packets transmitted over a network (104) from a source server (101). The invention applies solely to the field of continuously transmitted data. The device (108) comprises a network buffer memory (110) in which the packets may be stored and which exhibits a variable memory insertion time and means (120) for adapting the buffer memory insertion time with a view to improved playback performance. The device (108) furthermore comprises means (121) for locally determining the value of at least one quality of service indicator (135, 136, 137), the means (120) for adapting the buffer memory insertion time adapting this time as a function of the value of the indicator.

Description

technical field [0001] The invention relates to a device for streaming reception of audio and / or video data packets transmitted over a network from an origin server. The invention is only applicable in the field of transmission of data in streaming mode and thus concerns data that must be played in real time: the invention does not concern data that is initially downloaded and recorded on a receiving device and then played back. More specifically, the present invention relates to the field of devices connected to IP ("Internet Protocol") type data packet transmission networks without quality of service guarantees, existing IP network architectures are referred to as "best effort" architectures, This architecture does not provide guaranteed quality of service. The term QoS (an acronym for "Quality of Service") applied to packet-switched networks denotes the ability to provide a service according to demand, in particular in terms of response time, bandwidth or packet loss. In ...
