Abstract
(EN)
A stream device management system is provided for supporting applications that access a variety of stream devices associated with a conventional set-top box. More specifically, the stream device management system includes a stream manager configured to identify a plurality of stream devices and to store a device identifier for each of these stream devices, and a shared memory for storing stream data associated with each of the stream devices. To initiate communication with a first stream device, a first application sends a device identifier indicative of the first stream device to the stream manager. In response to receiving the device identifier, the stream manager communicates an address for the shared memory associated with the first stream device to the first application. Lastly, the application uses this address to access the stream data.

L'invention concerne un système de gestion de dispositifs générateurs de flux qui prend en charge divers dispositifs générateurs de flux associés à un décodeur traditionnel. L'invention concerne notamment un système de gestion de dispositifs générateurs de flux qui comprend un gestionnaire de flux configuré pour identifier plusieurs dispositifs générateurs de flux et pour stocker un identificateur de dispositifs pour chacun des ces dispositifs générateurs de flux, et une mémoire partagée destinée à stocker les données de flux associées à chacun de ces dispositifs générateurs de flux. Pour commencer la communication avec un premier dispositif générateur de flux, une première application envoie un identificateur de dispositifs indiquant au gestionnaire de flux la présence d'un premier dispositif générateur de flux. Dès réception de l'identificateur de dispositifs, le gestionnaire de flux communique à la première application une adresse pour la mémoire partagée associée au premier dispositif générateur de flux. En dernier lieu, l'application utilise cette adresse pour accéder aux données de flux.
