Title
(EN) METHOD OF TRANSFERRING DIGITAL SIGNAL
(FR) PROCEDE DE TRANSFERT DE SIGNAUX NUMERIQUES
Abstract
(EN)
A digital signal transferring method wherein in a serial transfer of a digital data signal of N-channel (N represents 16, 24, 32, for example), the digital data is divided into groups each consisting of data of K channel (K represents 8, for example) and successively and repeatedly transferred in sequence every M groups (M represents 2, 3, 4, for example). A preamble having such a pattern as violating regulations of the modulation system in the transfer of the data is disposed at, for example, the top of each of the groups. In addition, a data significance evaluation bit is added to every data for each of the channels, and each of the groups is provided with a parity data with respect to all the bits in the group, thereby to effect a signal transfer. Further, each of the groups may be provided with a group address for indicating where the group is in the M groups.

Procédé de transfert de signaux numériques dans lequel lors du transfert sériel d"un signal de données numériques de N canaux (N représente par exemple 16, 24, 32 par exemple), les données numériques sont divisées en groupes se composant chacun des données de K canaux (K représente 8, par exemple) et successivement et répétitivement transférées en séquences tous les M groupes (M représente par exemple 2, 3, 4). Une position de synchronisation possèdant un motif contraire aux règles du système de modulation dans le transfert des données est disposée, par exemple, au sommet de chaque groupe. En outre, on ajoute un bit d"évaluation de signification de données à chaque donnée pour chacun des canaux, et chaque groupe est pourvu d"une donnée de parité par rapport à tous les bits dans le groupe, de manière à effectuer un transfert de signaux. Chaque groupe peut également être pourvu d"une adresse de groupe indiquant l"emplacement de ce groupe dans les M groupes.
