Abstract
A method comprising: receiving a scalable video coding (SVC) encoded video data from a source of digital video data, the SVC-encoded video data carrying a video content, the SVC-encoded video data including a network abstraction layer (NAL) extension header, a first layer for the video content, and a second layer for the video content, the first layer including first video data utilized to retrieve the video content in basic quality from the SVC-encoded video data, the second layer including second video data utilized along with the first video data to retrieve the video content in enhanced quality from the SVC-encoded video data; parsing the NAL extension header to identify the first and second video data; assigning a higher priority to the first video data for retransmission relative to the second video data; caching the first and second video data with the assigned priority in a buffer memory; monitoring a digital data network to collect first network transport conditions, the digital data network being connected in signal communication with a receiver, the digital data network involving first and second data transport protocols, the first protocol being less reliable than the s…
