1. A method for decoding media encoded using scalable coding with temporal scalability at a pre-determined maximum temporal level, the method comprising:
- receiving signaling information that is indicative of a temporally nested structure of layers and pertains to all frames of a coded video sequence; and
decoding with a decoding device those parts of the encoded media signal which correspond to temporal levels that are less than or equal to the maximum temporal level,wherein the signaling information indicates for any three frames picA, picB, picC included in the coded video sequence, that picB is not used for reference of picA;
under a first condition that picB is of a temporal level lower or equal than the temporal level of picA, andunder a second condition that the temporal level of picC is lower than the temporal level of picB, andunder a third condition that picC follows picB in decoding order, andunder a fourth condition that picC precedes picA in decoding order.

Abstract
Media communication systems and methods for media encoded using scalable coding with temporal scalability are provided. Transmitting endpoints include switching information in their transmitted media to indicate if temporal level switching at a decoder can occur at any frame of the transmitted encoded media.
