Radio access network-based transmission control of layer-encoded media frames |
摘要 |
A technique for controlling transmission of layer-encoded media frames via a radio interface to a user terminal is presented. The layer-encoding defines a decoding-dependency of the media frames in terms of, for example, a base layer and one or more enhancement layers. A method implementation of the technique comprises receiving layer-encoded media frames at a radio access network and determining, at the radio access network, a decoding-dependency and a play-out sequence of the received media frames. The method further comprises identifying, from the media frame play-out sequence, a media frame for transmission via the radio interface and determining that the identified media frame is unavailable. In such a case, at least one media frame dependent from the unavailable media frame is identified from the media frame decoding-dependency, and the at least one dependent media frame is excluded from transmission via the radio interface. |
