Patent

CA 2601927

A method and apparatus for managing bandwidth of video and data over DSL is disclosed. Incoming packets of data are first inspected to determine if the data is video data or other (non-video) data. The video data is further analyzed to determine if it is intended for real-time delivery to the subscriber or if the video data is intended for viewing at a later time by the subscriber. Video data intended for real- time delivery to the subscriber is re-compressed to optimize the video quality. Statistical multiplexing is performed on the video data for real-time delivery, the video data for viewing at a later time, and the non-video data. The bandwidth needs for the video data for real-time delivery, the video data for viewing at a later time, and the non-video data are all evaluated. Bandwidth is then allocated to the video data for real--time delivery, the video data for viewing at a later time, and the non- video data, based on the video data service quality requirements and latency sensitivity of the non-video data.
