Abstract: The method involves receiving a package of a flow of coded video stream coming from a video coder through an interface screen. A transport interface is reconfigured, and a signal is transmitted through a broadcasting network. The flow package is stored in a database (412), where the flow package has a reference value for a program clock. A frame of a transport interface is provided in a queue. A research is performed in the queue corresponding to a request from a user who carries out an access through a communication network. The package is transmitted through the communication network. An independent claim is also included for a device for providing a video service.

Abstract: The apparatus (100) has a base layer processing unit (101) for converting multiple elementary streams into packets to generate a transport stream. A synchronization unit (103) generates information of a reference clock program of the transport stream to the base layer based on a system clock time. A multiplexing unit (160) generates a broadcasting stream by multiplexing a broadcast transport stream of the base layer with a dummy package. A transmission processing unit (170) transmits the broadcast stream through a transmission channel. Independent claims are also included for the following: (1) a method for synchronizing transport streams in a digital broadcasting system (2) a receiving apparatus comprising a receiving unit for receiving transport streams in a digital broadcasting system (3) a method of receiving transport streams in a digital broadcasting system.
