Abstract:
Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Synchronisieren eines Referenzbilds mit einem Zusatzbild eines Echtzeit-Rundfunkprogramms, wobei das Verfahren die folgenden Schritte umfasst: Erzeugen wenigstens eines Einzelbilds mit einer vorgegebenen Kennung, um für einen Empfänger im Voraus eine Mitteilung über die Anfangszeit des Referenzbilds bereitzustellen; und Übertragen wenigstens eines Einzelbilds mit der vorgegebenen Kennung an den Empfänger. Alternativ umfasst das Verfahren zum Synchronisieren eines Referenzbilds mit einem Zusatzbild eines Echtzeit-Rundfunkprogramms die folgenden Schritte: Erzeugen von Signalisierungsinformationen, die Zusatzbildverriegelungsinformationen enthalten, auf einer Sendeseite, um auf der Empfangsseite im Voraus auf das mit dem Referenzbild verriegelte Zusatzbild des Echtzeit-Rundfunkprogramms vorzubereiten; und Bereitstellen der Signalisierungsinformationen für den Empfänger. Somit ist es möglich, die Synchronisation eines 3D-Referenzbilds des Echtzeit-Rundfunkprogramms mit einem in dem Empfänger gespeicherten 3D-Zusatzbild oder mit einem gestreamten 3D-Zusatzbild genau und effizient auszuführen.
Abstract:
The present invention relates to a heterogeneous network-based linked broadcast content transmitting/receiving system and method. A transmission system generates a basic content stream on basic content constituting broadcast content and transmits the generated basic content stream to a terminal through a broadcast network, and also generates an additional content stream on additional content linked to the basic content and transmits the generated additional content stream to a terminal through a communication network. At least one of linkage playback information on the basic content and linkage playback information on the additional content is further transmitted to the terminal. Additionally, a reception terminal receives the basic content stream, the additional content stream, and the linkage playback information, and then synchronizes the basic content with the additional content and plays them back in order to playback broadcast content in real time.

Abstract:
The present invention relates to a method of synchronizing a reference image with an additional image of a real-time broadcasting program, the method comprising the steps of: generating at least one frame having a predetermined identifier for providing notice of the start time of the reference image to a receiver in advance; and transmitting at least one frame having the predetermined identifier to the receiver. Alternatively, the method of synchronizing a reference image with an additional image of a real-time broadcasting program comprises the steps of: generating signaling information containing additional image interlocking information at a transmission side in order to prepare for the additional image interlocked with the reference image of the real-time broadcasting program at a reception side in advance; and providing the signaling information to the receiver. Therefore, it is possible to accurately and effectively perform the synchronization of a 3D reference image of the real-time broadcasting program with a 3D additional image stored in the receiver or a streamed 3D additional image.
