Methods, apparatus, and computer readable storage medium for processing a media stream. The media stream may follow a DASH or CMAF standard. The method may include receiving media stream data comprising: a plurality of media chunks including a first media chunk and a second media chunk; and Addressable Resource Index (ARI) information associated with the first media chunk; determining track switching information based on the ARI information; determining, based on the track switching information, a switch to a different media track at the second media chunk is needed; and receiving the first media chunk and the second media chunk via respective media track, wherein each of the first media chunk and the second media chunk is delivered to the streaming client device with a delivery delay that is no more than one chunk.
