摘要:
According to one embodiment of the present invention, a method for transmitting an IPTV streaming service by P2P transmission comprises the steps of collecting TS packets of n skipped units to generate an encapsulation unit for an IPTV streaming service (where n is a natural number); adding an extension header containing type information to the generated encapsulation unit (wherein, said type information is information for identifying the sequence of the encapsulation unit, which is required for decoding the IPTV streaming service); adding an IP header to the encapsulation unit to which the extension header containing the type information is added, in order to generate an IP packet; and transmitting the generated IP packet to at least one super peers.
摘要:
A digital broadcasting system and a method of processing data are disclosed, which are robust to error when mobile service data are transmitted. To this end, additional encoding is performed for the mobile service data, whereby it is possible to strongly cope with fast channel change while giving robustness to the mobile service data.
摘要:
Disclosed are a method of transmitting and receiving a broadcast signal and an apparatus for receiving the broadcast signal. In the present invention, first program table information describing a broadcasting stream, and second program table information including additional service identifier information of the multiplexed stream and third program table information describing the additional service data for the multiplexed stream are obtained. The additional service can be provided with the additional service data by using the third program table information.
摘要:
The present invention is directed to a digital broadcast system and a data processing method. A broadcast signal in which mobile service data and main service dataare multiplexed is transmitted and received. Then, in a broadcasting receiver, the program table informationincluding information about a service or a program of an ensemble is parsed according to an identifier of the ensemble in which the mobile service data are multiplexed, in the received broadcast signal. And a mobile service is outputted by using the mobile service data and the parsed program table information.
