CA 2375375

A wireless packetization apparatus for transmitting/receiving multimedia data including video data in a radio transmitting/receiving system, and a method thereof are provided. According to the present invention, error resilience can be increased by adding an error protection code and a corruption indication flag to header information on a radio link protocol (RLP) layer when multimedia data such as video data requiring real time or low delay is transmitted and received in a wireless environment, and a packet drop rate can be thereby reduced.

Appareil sans fil de mise en paquets pour la transmission/réception de données multimédia, y compris de données vidéo, dans un système d'émission/réception radio, et procédé associé. Selon la présente invention, la résistance aux erreurs peut être améliorée par ajout d'un code de protection d'erreurs et d'un fanion d'indication d'altération aux informations d'en-tête sur une couche de protocole RLP lorsque des données multimédia telles que des données vidéo nécessitant le temps réel ou un faible délai sont transmises et reçues dans un environnement sans fil, ce qui permet ainsi de réduire le taux de suppression de paquets.
