摘要:
A moving picture coding apparatus (10) for performing inter-picture predictive coding on pictures constituting a moving picture is provided with a coding unit (103) for performing predictive error coding on image data; a decoding unit (105) for performing predictive error decoding on an output from the coding unit (103); a reference picture memory (117) for holding output data from the decoding unit (105); and a motion vector detection unit (108) for detecting forward and backward motion vectors on the basis of decoded image data stored in the memory (117). When coding a B picture, a picture that is timewise closest to the target picture is used as a candidate picture for forward reference, and an I or P picture that is timewise closest to the target picture is used as a candidate picture for backward reference. The moving picture coding apparatus (10) so constructed can improve coding efficiency of a B picture to be subjected to bidirectional predictive coding.
摘要:
There is provided a system and method for the synchronizing on-air commercial programming with interactive applications, providing interactive content synchronized with on-air television programming. There is provided a system comprising a client device with a display device and an input device and running a synchronization application. The client device receives digital data transmitted from a server, and transmits user feedback information generated from user interactions with the digital data back to the server. The digital data are interactive advertisements, such as online social games, that increase users' awareness of the advertised products or messages. The digital data are delivered to the user's client device in synchronization with the broadcasting of on-air television commercials.
