Abstract: Synchronous playback of time-based media received from one or more locations remote from a primary editing/mixing studio is achieved by time-stamping media samples with a local presentation time before streaming them to the primary studio. At the primary studio, samples having the same presentation timestamp are played back at the same time, independently of the samples' arrival time at the playback system. Media stored locally to the playback system may also be included as part of the synchronous playback using locally computed presentation times. In order to accommodate media streaming transmission delays, the playback system negotiates a suitable delay with the remote systems such that samples corresponding to a given presentation time are received at the playback system from remote locations prior to playback of media corresponding to the given presentation time.

Abstract: Audio data is prevented from not synchronizing with video data when splicing. A first GOP of a video stream of a second program is spliced to a last GOP of a video stream of a first program. A first GOP of an audio stream of the second program is spliced to a last GOP of an audio stream of the first program. In this case, a gap amount PTS_FS required for synchronizing video data and audio data after the splicing is computed for each GOP. For the splicing processing, a gap amount PTS_FS_SPLYCE caused when the last GOP is spliced to the first GOP directly and the PTS_FS are used.

Abstract: A computing system that has access to a streamed multimedia sample that is stored on a storage medium applies a zero-based presentation timestamp numbering scheme to the data packets of the multimedia sample, on-the-fly, and after each seek operation. After seeking to a desired starting point, the computing system reads ahead a maximum number of data packets within each media stream of the multimedia sample. A smallest timestamp (normalizing presentation timestamp) is identified and then subtracted from the timestamps of the data packets that are transmitted to the appropriate rendering devices, thereby creating appropriate presentation timestamps for the data packets for synchronizing the playback of the multimedia sample.

Abstract: A modified Colorstripe™ copy protection process utilizes a basic anti-copy protection (ACP) signal that causes attenuation of a video signal, wherein, in one embodiment, the process modifies (lowers) the level of a front porch portion and adds an incorrect color signal (color burst) in the region of the sync tip. When an illegal copy is made, a pre-blanked end of line portion causes a TV set to trigger the color burst sample pulse ahead of time and cause the incorrect color signal in the sync tip region to be sampled. Thus, since the sync tip region has incorrect color phase or frequency, the resulting illegal copy will have enhanced color distortions. In other embodiments, other portions of the horizontal blanking interval are lowered in level and incorrect color bursts are added to a portion or portions of the back porch and/or a portion of the front porch.
