Abstract
An apparatus and a method for transmitting multimedia data in a hybrid network are provided. The apparatus includes a payload part including at least one of first data synchronized according to a time to be reproduced and second data other than the first data, a first header part including information on the payload part, a packet part for generating a packet, the packet part including a second header part including information on the packet, and a transceiver for generating and transmitting a signal including the payload part, the first header part, and the packet part to the hybrid network.
Claims8
An apparatus for receiving a packet in a multimedia system, the apparatus comprising:
- a transceiver configured to receive, from a transmitting entity, a moving picture experts group media transport (MMT) packet including a header region and a payload, wherein the MMT packet is different from a real-time transport protocol (RTP) packet;
- and
- a controller configured to process data in the payload based on information in the header region,
- wherein the information in the header region of the MMT packet comprises:
- data unit type information including a value indicating whether the payload includes a data unit of a complete type,
- an indicator used to distinguish media data to which the MMT packet belongs from another media data,
- a one-bit flag, wherein if the one-bit flag has a first value;
- the one-bit flag indicates that the payload includes only one data unit, and if the one-bit flag has a second value the one-bit flag indicates that the payload includes more than one data unit, and
- payload type information indicating whether the payload includes one or more control messages.
