Abstract
Embodiments of a method and apparatus for preparing a first node of a communications system for transmitting an encoded digital signal to a second node of the communication system is described for providing Terminal QoS. The encoded digital signal is generated from a digital signal, the first node providing the encoded digital signal and the first node having access to display parameters associated with the digital signal. The second node is for at least decoding the encoded signal within an execution time and for subsequent display, the encoding and/or decoding being defined by at least one encoding-decoding scheme in accordance with coding parameters. The coding parameters are determined for encoding-decoding in accordance with one or more first display quality measures of the decoded signal after decoding, one or more execution times of the decoding of the encoded digital signal, and one or more second display quality measures.
