Data Broadcasting Georgiy Shenderovich Proprietary georgiysh@gmail.com, ph.: +972-544-491911+972- 544-24 25. Data BroadcastingData Piping - where discrete pieces of data are delivered using containers to the destination. There is no timing relationship between the data and other PES packets.Data Streaming - where the data takes the form of a continuous stream which may be Asynchronous (i.e. without timing, as for Internet packet data) Synchronous (i.e. tied to a fixed rate transmission clock, as for emulation of a synchronous communication link) or Synchronised (i.e. tied via time stamps to the decoder clock and hence to other PES packets, as for the display of TV captions). The data is carried in a PES.Multi-Protocol Encapsulation (MPE) - the technique is based on DSM-CC and is intended for providing LAN emulation to exchange packet dataData Carousels - a scheme for assembling data sets into a buffer which are played-out cyclic manner (periodic transmission). The data sets may be of any format or type. One example use is to provide the data for Electronic Programme Guides (EPGs). The data are sent using fixed sized DSM-CC sections.Object Carousels - object carousels resemble data carousels, but primarily intended for data broadcast services. The data sets are defined by the DVB Network Independent Protocol specification. They may be used, for example, to down-load data to a set top box decoder Georgiy Shenderovich Proprietary georgiysh@gmail.com, ph.: +972-544-491911+972- 544-25 26.
