Title (EN) DATA FLOW CONTROL METHOD AND APPARATUS
(FR) PROCÉDÉ ET APPAREIL DE RÉGULATION DE FLUX DE DONNÉES
(ZH) 一种数据流控方法及装置
Abstract:
(EN) Disclosed are a data flow control method and apparatus. The method comprises: a device computing, when a clock signal arrives, the quantity of transition minimized differential signaling (TMDS) characters currently stored in a buffer of the device; and the device outputting, when the quantity of TMDS characters currently stored in the buffer reaches a pre-set value, the TMDS characters in the buffer, otherwise, outputting a gap data packet, wherein the pre-set value is less than or equal to the capacity of the TMDS characters stored in the buffer. By using the method and the apparatus of the present application, an inherent display time sequence of TMDS characters can be ensured.
(FR) L'invention concerne un procédé et un appareil de régulation de flux de données. Le procédé comporte les étapes suivantes: un dispositif calcule, lorsqu'un signal d'horloge arrive, la quantité de caractères de signalisation différentielle à transitions minimisées (TMDS) actuellement stockée dans un tampon du dispositif; et le dispositif délivre, lorsque la quantité de caractères de TMDS actuellement stockée dans le tampon atteint une valeur prédéfinie, les caractères de TMDS présents dans le tampon, et délivre si ce n'est pas le cas, un paquet de données d'intervalle, la valeur prédéfinie étant inférieure ou égale à la capacité des caractères de TMDS stockés dans le tampon. En utilisant le procédé et l'appareil de la présente invention, un ordre chronologique inhérent d'affichage de caractères de TMDS peut être garanti.
(ZH) 本申请公开了一种数据流控方法及装置,其中,该方法包括:设备在时钟信号到达时,计算所述设备的缓冲器中当前存储最小化传输差分信号TMDS字符的数量;所述设备在所述缓冲器中当前存储TMDS字符的数量达到预设值时,输出所述缓冲器中的TMDS字符;否则,输出空数据包;其中,所述预设值小于等于所述缓冲器存储TMDS字符的容量;采用本申请的方法及装置,可保证TMDS字符固有的显示时序。
