Simplified transmission method for a stream of signals between a transmitter and an electronic device

摘要

A multimedia data transmission method between a transmitter server and at least one decoder receiver the multimedia data being transmitted by packets in a stream of samples coding images (I, P, B) of variable size, the method includes: determining a same transmission delay for all the samples of the stream, determining a transmission bitrate for each sample enabling the sending of this sample within the determined transmission delay, transmitting each sample from the transmitter server to the decoder receiver while respecting the transmission bitrate specific to this sample and the transmission delay of all the samples.

1. A method for transmission, by a transmitter server via a communications network using a packet data transmission protocol, of a stream of multimedia samples, said stream being composed of samples of intra, predictive and bi-predictive coding images (I, P, B) of variable size, wherein the method comprises:
allocating a same transmission delay (dt) for each sample of the stream, said transmission delay corresponding to a presentation delay of each image, setting a maximum transmission bitrate of samples, for each first sample:
determining a transmission bitrate specific to said first sample enabling the sending of said first sample within said allocated transmission delay (dt), when said determined transmission bitrate is inferior to said maximum transmission bitrate, transmitting said first sample while respecting said determined transmission bitrate and said allocated transmission delay (dt) of all the samples; when said determined transmission bitrate exceeds said maximum transmission bitrate:
transmitting a first part of said first sample while respecting said maximum transmission bitrate and said allocated transmission delay (dt);when the transmission of a second sample following said first sample can be carried out in a delay equal to said allocated transmission delay reduced by the timeout relative to the transmission of a second part of said first sample that has not been transmitted during the transmission delay allocated to said first sample, using the transmission delay allocated to said second sample for the transmission of said second part of said first sample.
