Abstract

La présente invention porte, dans des modes de réalisation, sur un procédé de codage ainsi que sur un appareil et un système associés. Le procédé comprend les étapes suivantes : un terminal de codage détermine un type de trame d'une trame JESD204 cible dans les données JESD204B qui doivent être transmises ; le terminal de codage code la trame JESD204 cible à l'aide d'une technique de codage 64B66B pour obtenir une trame de transmission de 66 bits ; le terminal de codage transmet la trame de transmission à un terminal de décodage ; le terminal de décodage omet une vérification de données d'une trame de transmission dans laquelle un en-tête de trame transporte un premier identifiant et les données transportées dans chacun des 8 octets sont D28.5 ; et le terminal de décodage omet une vérification de données d'une trame de transmission dans laquelle un en-tête de trame transporte un premier identifiant et des données transportées dans un nième octet des 8 octets est D28.0. Le procédé basé sur les modes de réalisation de la présente invention est capable d'améliorer l'efficacité de codage.
