Abstract: A technique is disclosed for controlling data packet transmissions from a server to a client having a client buffer in accordance with a waiting mode and a dynamic mode. The waiting mode is performed before packets containing data encoded subject to a current bit rate have reached the client buffer; the dynamic mode is performed otherwise. In the waiting mode, down-switches to lower bit rates are allowed but up-switches to higher bit rates are disabled. In the dynamic mode, up-switches and down-switches are both allowed, with adjustments in the bit rate of packets controlled based, in part, on the amount of data contained within the client buffer when packets containing data encoded subject to the current bit rate first reached the client buffer. The two modes help avoid unnecessary rate switches.

Abstract: Método para controlar transmisiones por paquetes de datos de velocidad binaria variable desde un servidor (105) a un cliente (115) que tiene una memoria intermedia (155) de cliente, en el que el servidor conmuta entre versiones diferentes de un flujo continuo de datos de velocidad binaria variable que se están transmitiendo basándose en un estado de la memoria intermedia del cliente, comprendiendo el método las etapas de: seleccionar (202) una versión inicial de un flujo continuo de datos de velocidad binaria variable para su transmisión; realizar (204) un seguimiento de un valor (PT) representativo de una cantidad de datos dentro de la memoria intermedia del cliente; determinar (206) una velocidad binaria (BR) de una parte de datos de velocidad binaria variable todavía por transmitir dentro de la versión seleccionada del flujo continuo; y controlar conmutaciones (212) a versiones diferentes del flujo continuo, que presentan velocidades binarias medias diferentes, basándose en el valor (PT) representativo de la cantidad de datos dentro de la memoria intermedia del cliente en combinación con la velocidad binaria (BR) de la parte de datos de velocidad binaria variable todavía por transmitir.
