Abstract: An encoder and corresponding method are disclosed for performing video rate control to meet network traffic model restrictions, including pre-encoding the sequence of pictures for each of a plurality of quantization parameter values, selecting for each picture of the sequence one of the plurality of quantization parameter values responsive to the quantization parameter values and bitrate operating points of the neighboring pictures in the sliding time window, and encoding each picture of the sequence using the quantization parameter value selected for that picture.

Abstract: A method for transmitting prioritized data encoded by a Forward Error Coding operation wherein a media object is separated into different classes of data forming a base layer and at least one enhancement layer of information, with each layer having associated parity data. Data of the separated media object, formed of classified data, is later encoded and stored, whereby information of the base layer is assigned a higher priority for transmission than enhancement layer data. Such priority classifications are used when a server transmits the classified data over a network fabric as prioritized data. Optionally, the composition of transmitted classified data is adjusted in view of a change in network conditions.
