Title (EN) PROVIDING PRECISION TIMING PROTOCOL (PTP) TIMING AND CLOCK SYNCHRONIZATION FOR WIRELESS MULTIMEDIA DEVICES
(FR) FOURNITURE D’UNE TEMPORISATION DE PROTOCOLE DE TEMPORISATION DE PRÉCISION (PTP) ET D’UNE SYNCHRONISATION D’HORLOGE POUR DES DISPOSITIFS MULTIMÉDIAS SANS FIL
Abstract:
(EN) Providing Precision Timing Protocol (PTP) timing and clock synchronization for wireless multimedia devices is disclosed. In one aspect, a primary wireless multimedia device comprising a timing synchronization control system is provided. The timing synchronization control system is configured to apply a PTP Best-Master-Clock (BMC) algorithm logic to select a master clock from among a system clock of the primary wireless multimedia device, one of one or more connected wireless multimedia devices, or one of one or more external nodes. If the timing synchronization control system selects the system clock of the primary wireless multimedia device, a clock signal of the system clock is provided to the connected wireless multimedia devices as the master clock. If the timing synchronization control system selects a connected wireless multimedia device or an external node as the master clock, the timing synchronization control system synchronizes the system clock with the master clock.
(FR) L’invention concerne la fourniture d’une temporisation de protocole de temporisation de précision (PTP) et d'une synchronisation d’horloge pour des dispositifs multimédias sans fil. Selon un aspect, un dispositif multimédia sans fil primaire comprenant un système de commande de synchronisation de temporisation est proposé. Le système de commande de synchronisation de temporisation est configuré pour appliquer une logique d’algorithme de la meilleure horloge maître (BMC) PTP pour sélectionner une horloge maître parmi une horloge de système du dispositif multimédia sans fil primaire, de l’un du ou des dispositifs multimédias sans fil connectés, ou de l’un d’un ou plusieurs nœuds externes. Si le système de commande de synchronisation de temporisation sélectionne l’horloge de système du dispositif multimédia sans fil primaire, un signal d’horloge de l’horloge de système est fourni au dispositif multimédia sans fil connecté sous la forme de l’horloge maître. Si le système de commande de synchronisation de temporisation sélectionne un dispositif multimédia sans fil connecté ou un nœud externe comme horloge maître, le système de commande de synchronisation de temporisation synchronise l’horloge de système avec l’horloge maître.
