Patent ID: 11483365

Abstract:
Methods and apparatus are disclosed for selecting an encoding specification for encoding audio and/or video data to be streamed between a user-device (11) and a remote device (28), where the user-device is operable to communicate with the remote device via a digital subscriber line (DSL, 13) for a portion of a path (29) between the user-device and the remote device, the DSL portion (13) extending between a user-side DSL modem device (22) and a DSL aggregation transceiver device (24). The method comprises: at the user-side DSL modem device (22) and/or the DSL aggregation transceiver device (24), collecting performance data in respect of data communications on the DSL portion (13); in dependence on the performance data collected, determining one or more data communication characteristics in respect of data communications on the DSL portion (13); and selecting an encoding specification for encoding the data to be streamed, the selection being made in dependence on the determined data communication characteristics.
