| 20110052137 | System and method for effectively utilizing a recorder device - A system and method for effectively utilizing a recorder device includes a timecode generator that generates timecode for synchronizing electronic information. A transceiver of the recorder device wirelessly transmits the timecode to a plurality of cameras. The cameras capture video data and audio data, and timecode managers of the respective cameras combine the received timecode with the captured video data and audio data to produce camera data. The cameras then wirelessly transmit the camera data to the recorder device for storage in a recorder memory. The recorder device may also receive and store PA audio data from a public address system. Furthermore, a computer device may communicate with the recorder device to perform various types of editing procedures on the stored camera data and PA data to produce edited data. | 03-03-2011 |
| 20110206343 | METHOD AND APPARATUS FOR RECEIVING METADATA, EPG, OR IPG SIGNALS IN AN INTEGRATED CIRCUIT FOR CONTROL PURPOSES - An integrated circuit or system receives a bit pattern from a metadata, IPG, and or EPG signal. This bit pattern is then coupled to a circuit to provide a content control command to a recorder or to a processing circuit to generate a content control signal. In particular the bit pattern may be utilized in a manner to program, enable, or disable the generated control signal. Furthermore this content control signal provides resistance to a circumvention device. For example, the circumvention device is unable to remove sufficiently the content control signal, and content control is maintained. | 08-25-2011 |
| 20140010515 | PLAYBACK SYNCHRONIZATION - Various exemplary embodiments relate to method and media devices for synchronizing media playback between a receiving media device and sending media device, including: receiving, at the receiving media device, a plurality of messages from the sending media device, wherein the plurality of messages include a plurality of sender timestamps; generating a plurality of clock offset values based on the plurality of sender timestamps and a clock of the receiving media device; identifying a minimum clock offset value from the plurality of clock offset values; locating first media data for playback and a first presentation time associated with the first media data; and causing the first media data to be rendered at a first time that matches the first presentation time based on the minimum clock offset. | 01-09-2014 |
| 20140079368 | DISPLAY DEVICE AND TRANSMISSION DEVICE - A display device comprising: a reception unit; a display unit; a storage unit; and an acquisition unit. The reception unit receives a stream containing a plurality of video frames and first display timing information specifying a display timing of each video frame. The display unit displays each video frame at a corresponding display timing specified by the first display timing information. The storage unit stores an image and second display timing information specifying a display timing of the image. The acquisition unit acquires correction information specifying a correction amount for correcting the display timing of the image and thereby enabling the image to be displayed in synchronization with the video frames displayed by the display unit. The display unit further displays the image at a corrected display timing determined by correcting the display timing of the image by using the correction amount specified by the correction information. | 03-20-2014 |
| 20150043885 | VIDEO DISPLAY APPARATUS AND VIDEO DISPLAY METHOD - According to an embodiment, an information processor includes a first decoder, a controller and a display unit. The first decoder decodes the first video encoded data at a first speed to generate a first video. When the first video encoded data is received earlier than the second video encoded data, the controller controls the first speed so as to generate a period in which the first speed becomes lower than a ×1 speed until second time information of the second decoder catches up with first time information of the first decoder. When the first video encoded data is received earlier than the second video encoded data, the first video is displayed at the first speed until the second time information catches up with the first time information. | 02-12-2015 |
| 20150356992 | TECHNIQUES TO EXTRACT ENF SIGNALS FROM VIDEO IMAGE SEQUENCES EXPLOITING THE ROLLING SHUTTER MECHANISM; AND A NEW VIDEO SYNCHRONIZATION APPROACH BY MATCHING THE ENF SIGNALS EXTRACTED FROM SOUNDTRACKS AND IMAGE SEQUENCES - Various systems and methods may benefit from determination of environmental signatures in recordings. For example, such signatures may aid forensic analysis and alignment of media recordings, such as alignment of audio or video recordings. A method can include extracting electric network frequency signals from an image sequence of a video recording or an audio recording. The method can also include synchronizing the video recording or the audio recording with at least one other datum based on the electric network frequency signals. | 12-10-2015 |
| 20160127614 | Video frame playback scheduling - Systems and techniques are provided for video frame playback scheduling. A presentation time for a frame of a video may be received. An offset for the frame of video may be determined based on succeeding frames of the video and Vsync pulse times. The presentation time for the frame of the video may be adjusted based on the offset to generate an adjusted presentation time that is closer to a halfway point between a first Vsync pulse and a second Vsync pulse than the presentation time. A cumulative time correction may be tracked based on adjustments made to the presentation times for frames of the video. A magnitude of the cumulative time correction may be determined to exceed the magnitude of a positive or negative threshold. The cumulative time correction may be added to or subtracted from based on the determination that the magnitude exceeds the positive or negative threshold. | 05-05-2016 |
| 20160134833 | APPARATUS, SYSTEMS AND METHODS FOR SYNCHRONIZATION OF MULTIPLE HEADSETS - Media device systems and methods synchronize video content with audio content presented by a plurality of wireless audio headsets. In an exemplary embodiment, a first time delay corresponds to a first duration of time between communication of the audio content from the media device and presentation of the audio content by a first wireless audio headset. A second time delay corresponds to a second duration of time between communication of the audio content from the media device and presentation of the audio content by a second wireless audio headset, wherein the first time delay is greater than the second time delay. Video content communicated to a display is delayed by the first time delay. Audio content communicated to the second wireless audio headset is delayed by a time delay difference between the first time delay and the second time delay. | 05-12-2016 |
