Question: In MBMS using FLUTE protocol, what is indicated about transporting multiple objects within a session?
Option 1: A unique Transport Object Identifier (TOI) is used for all objects.
Option 2: An additional SDP attribute is required to signal multiple object transport.
Option 3: No explicit indication or SDP attribute is needed, as multiple TOIs (including TOI 0 for FDT Instances) imply multiple objects.
Option 4: The A flag in packets with no payload serves as an indicator for multiple object transport.
Explanation: According to the context of MBMS and FLUTE protocol, utilizing multiple Transport Object Identifiers (TOIs), such as TOI 0 specifically for FDT Instances, inherently signifies that a session is transporting packets for more than one object. Therefore, there's no additional need for an explicit indication or a separate SDP attribute to convey this information to receivers. This approach aligns with efficient protocol design, minimizing overhead while maintaining clarity for receiver implementations.
