Method and apparatus for transmitting media data in multimedia transport system
A method for transmitting media data in a Moving Picture Experts Group (MPEG) Media Transport (MMT) system is provided. The method includes receiving a Media Processing Unit (MPU) fragmented into one or more Media Fragment Units (MFUs), generating one or more multimedia data packets each including a packet header and a payload, based on the MPU, and transmitting the one or more multimedia data packets to a terminal. A payload header included in the payload includes identification information indicating an MPU to which at least one MPU included in the payload belongs, and a counter indicating the number of the at least one MPU.
Transmission method, reception method, transmission apparatus, and reception apparatus
A transmission method includes: generating one or more transfer frames that each store one or more streams used for content transfer; and transmitting the one or more generated frames through broadcast, each of the one or more streams storing one or more second transfer units, each of the one or more second transfer units storing one or more first transfer units, and each of the one or more first transfer units storing one or more Internet Protocol (IP) packets. In at least one stream among the one or more streams, each of the first transfer units positioned at a head contains reference clock information indicating time used for reproduction of the content.
Method of transmitting and receiving broadcasting channel and device therefor
The present disclosure provides a method of transmitting a Physical Broadcasting Channel (PBCH) by a base station in a wireless communication system. Particularly, the method may include generating a PBCH payload including bits indicating a frame in which the PBCH is transmitted; scrambling at least some of the bits included in the PBCH payload using second and third least significant bits among the bits; and transmitting the bits of the PBCH payload including the at least some scrambled bits to a user equipment.
Apparatus and method for media streaming
A system that incorporates teachings of the subject disclosure may include, for example, dividing a media content item into a plurality of media content segments, at each media content segment of the plurality of media content segments, applying motion estimation between at least two video frames of the media content segment to determine a content weight for the media content segment, determining a bit rate for the media content segment according to the determined content weight for the media content segment, and encoding the media content segment at the determined bit rates to generate a data stream for the media content segment, whereby a plurality of data streams for the plurality of media content segments of the media content are generated, and transmitting the plurality of data streams for the plurality of media content segments of the media content to the one or more media devices. Other embodiments are disclosed.

TECHNIQUES FOR CLIENT-CONTROLLED PACING OF MEDIA STREAMING
In various embodiments, a media delivery application transmits encoded chunks of a media title to a playback application. In operation, the media delivery application receives, via a media channel, an encoded chunk request that has been transmitted over a TCP connection. The media delivery application also receives, via a side channel, a pacing specification that is associated with the encoded chunk request and has been transmitted over the TCP connection. As per the encoded chunk request, the media delivery application retrieves encoded chunk content. The media delivery application sets a parameter associated with the TCP connection equal to a parameter value based on the pacing specification. Subsequently, the media delivery application causes TCP segments corresponding to the encoded chunk content to be transmitted, via the media channel, over the TCP connection in accordance with the first parameter value.
Convergence sublayer for use in a wireless broadcasting system
A method of encapsulating data and a single frequency network configured to perform the method are disclosed. A content stream of data packets is received, and the data packets in the content stream are formatted in accordance with a first protocol. Information identifying a container size established for the content stream is received. The data packets formatted in accordance with the first protocol are fragmented and packed to form data units formatted in accordance with a second protocol, and the data units are sized based on the container size. The data units formatted in accordance with the second protocol are encapsulated to form second protocol data packets. The second protocol data packets are provided to a transmitter that is synchronized to one or more transmitters in a single frequency network so that each transmitter in the single frequency network broadcasts a same signal that includes the second protocol data packets.
