Abstract:
1. An apparatus for providing a Quality of Service (QoS) of Audio-Visual (AV) streams, the apparatus comprising: a determination unit that identifies types of data including AV streams and general data; a time division multiple access (TDMA) scheduler that assigns time division periods for processing the AV streams and the general data during a predetermined recurring time period in accordance with an identification result from the determination unit; an input port that receives the data including the AV streams and the general data; a buffer that stores the AV streams and the general data in memory areas respectively corresponding to the assigned time division periods; and an output port that extracts and outputs the AV streams and the general data stored in the buffer, wherein sizes of the memory areas of the buffer are dynamically varied to correspond to respective time division periods in the recurring time period, wherein the determination unit identifies the types of the data before the input port receives the data, and wherein the assigned time division periods include a plurality of isochronous periods for processing the AV streams and a plurality of asynchronous periods for processing the general data.
