Abstract:
The invention relates to a method for improving the reliability and the reception quality of video data streams over a wireless network controlled by Wi-Fi communication protocols, the video data stream being encoded in the form of packets Q each including K first data blocks and H redundancy blocks for forward error correction (FEC), said stream comprising a series of packets G each including K+N blocks which are transmitted by at least one transmitting device multicasting same to client viewing devices such as smartphones. Said method includes the following steps, implemented by the client device for each of the data packets G received from the one or more transmitting devices: a/ monitoring the correct reception of the K first data blocks, decoding and viewing the video stream if the result is positive; b/ if all of the K first data blocks are not received, decoding if possible by means of a forward error correction (FEC) algorithm; c/ if the total number X of K+N blocks received is lower than K or if a positive result is not obtained from the preceding decoding step, sending a message regarding the one or more lost blocks; d/ if a statistical algorithm of the transmitting device organises the resending of the missing data, checking reception of data according to a/ and b/, decoding and viewing the video stream if the result is positive.

Claim (Index 3):
The method for enhancing the reliability and the quality of reception of video data streams over a wireless local area network according to  claim 2 , characterized by the following steps:\n h/ in case of non-reception of a reference image with internal coding in the data packet G received, checking the reception of at least one reference image of the preceding G\u22121 and next G+1 packets, i/ implementing an interpolation method on the uncompressed or linear data for the reconstruction of images, then j/ decoding and viewing the video stream.
