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:
Disclosed are a signaling method for a stereoscopic video service and an apparatus using the method. An image decoding method comprises: a step of determining a field value based on a broadcast service type and a display mode in decoding a program level descriptor; and a step of determining an encoded stream type, whether an elementary stream is a reference stream, whether the elementary stream is a left-eye image or a right-eye image, additional image upsampling information and information on a subsampled line. Thus, efficiency of encoding/decoding an additional image for a stereoscopic video content may increase.
Abstract:
Method and device for synchronizing reference image and supplementary image in real-time broadcast program. The present invention provides a synchronization method for: calculating a time difference between a current frame of a reference image and a reference time stamp on the basis of the reference time stamp, which is contained in a program level descriptor and indicates a start time of a frame regarding a reference image; and adjusting synchronization between the frame regarding the reference image and a frame regarding a supplementary image by using the time difference. Since synchronous time information is signaled together with a stream delivered in real time, synchronization between a stored supplementary image and a reference image transmitted in real time is enabled even though a first PMT of a time when a stereoscopic video service is started is not received or a packet error is generated. Thus, the invention can provide a stable stereoscopic image service
Abstract:
Disclosed are an image encoding method using a skip mode and a device using the method. The image encoding method may comprise the steps of: judging whether there is residual block data of a prediction target block on the basis of predetermined data indicating whether residual block data has been encoded; and, if there is residual block data, restoring the prediction target block on the basis of the residual block data and an intra-screen predictive value of the prediction target block. Consequently, encoding and decoding efficiency can be increased by carrying out the encoding and decoding of screen residual data only for prediction target blocks where there is a need for a residual data block in accordance with screen similarity.
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.
