摘要： A display apparatus can avoid a load increase and display rapidly the video of a selected channel. The display apparatus includes a synchronizing unit. The synchronizing unit adjusts a timing, in which a video is displayed based on a predetermined reference frame received and decoded at first after channel selection, toward shifting earlier than a time of original display of the video based on a time information attached to the reference frame.

摘要： Techniques to synchronize video data and audio data of a video-call over heterogeneous communications transports are disclosed. A transmitting client device adds synchronization indicia for a first communications transport to the video data and synchronization indicia for a second communications transport to the audio data. A receiving client device receives the video and audio data in a buffer, synchronizes the video and audio data, and removes the synchronization indicia for both the video and audio data with a filter. Disclosed techniques to optimize the synchronization include selectively dropping video frames in order to reduce delay, to reduce memory footprint, or to meet quality of service levels as set by a user.

摘要： This invention relates to a device and a method of generating a first and a second fingerprint (102,104) usable for synchronization of at least two signals (101,103) and corresponding method and device for synchronizing two or more signals. A fingerprint pair is generated on the basis of a segment of a first signal e.g. an audio signal and of a segment of a second signal e.g. a video signal at each synchronization time point. The generated fingerprint pair(s) are stored in a database (203) and communicated or distributed to a synchronization device (303). During synchronization, fingerprint(s) of the audio signal and fingerprint(s) of the video signal to be synchronized are generated and matched against fingerprints in the database. When a match is found, the fingerprints also determine the synchronization time point, which is used to synchronize the two signals. In this way, a simple, reliable and efficient way of synchronizing at least two signals is obtained. Further, this is enabled without modifying either the first and second signal (or subsequent signals). The signals may even be distorted or changed to some extent while still enabling synchronization.
