20080266453 | Automatic Determination of Local Time for Terrestrial Broadcast Digital Television Receiver - A method by which a DTV receiver that receives a terrestrial broadcast DTV signal may automatically determine the local time for the local terrestrial broadcast region, as well as DTV receivers that implements such a method, is described. The method includes obtaining a unique identifier of a terrestrial broadcast signal, wherein the unique identifier is transmitted as part of the terrestrial broadcast signal, accessing a memory to obtain a local time offset and a Daylight Savings Time (DST) observance indicator associated with the unique identifier, and calculating the local time based on the local time offset and the DST observance indicator. Additional methods for providing channel availability information to a user based on the unique identifier are described. | 10-30-2008 |
20100295993 | APPARATUS AND METHOD FOR SYNCHRONIZATION BETWEEN VIDEO AND AUDIO IN MOBILE COMMUNICATION TERMINAL - An apparatus and a method for synchronization between video and audio in a mobile communication terminal are provided. The method for the synchronization between the video data and the audio data in the mobile communication terminal includes acquiring Presentation Time Stamp (PTS) information for each of audio data and video data which need to be played simultaneously; determining a delay time between the terminal and a wireless device which plays one data of the audio data and the video data; generating new PTS information for the one data by reflecting the determined delay time in the PTS information; and synchronizing the one data and the other data using the new PTS information for the one data and the acquired PTS information for the other data. | 11-25-2010 |
20100315553 | AUDIO-VIDEO DATA SYNCHRONIZATION METHOD, VIDEO OUTPUT DEVICE, AUDIO OUTPUT DEVICE, AND AUDIO-VIDEO OUTPUT SYSTEM - To provide an audio-video data synchronization method whereby an increase in the amount of control message transmission can be suppressed and the video output can be prevented from being interrupted. The audio-video data synchronization method includes: obtaining, by the audio output device, a first latency that is a period of time taken for the video output device to output the video, by receiving the display identification data that includes information indicating the first latency from the video output device when the indication of the connection validity status information changes from Invalid to Valid; adjusting, by the audio output device, timing of outputting the audio according to the first latency; obtaining, by the video output device, a second latency which is a period of time taken to output the video in the outputting; notifying the audio output device of the second latency by sending a control message from the video output device when the connection validity status information indicates Valid, the control message including information that indicates the second latency obtained in the obtaining of a second latency; and adjusting, by the audio output device, timing of outputting the audio according to the second latency. | 12-16-2010 |
20140078399 | VIDEO PROJECTOR AND ASSOCIATED DATA TRANSMISSION - A video projector, a cluster of video projectors and a method for wirelessly transmitting image data within the cluster of video projectors. The video projector includes a first antenna located at a first side of the projector and a second antenna located at a second side of the projector, opposite to the first side. Image data is divided into sub-parts, and distributed by assigning each image data sub-part to a video projector. A video projector receiving image data sub-parts extracts and stores the image data sub-part assigned to it, and retransmits image data sub-parts assigned to respectively a second and third video projectors. | 03-20-2014 |
20140333836 | APPARATUS AND METHOD FOR ADDING SYNCHRONIZATION INFORMATION TO AN AUXILIARY DATA SPACE IN A VIDEO SIGNAL AND SYNCHRONIZING A VIDEO - A video synchronization apparatus and method by adding sync data to an ancillary data space of a video signal are provided. A sync data adding apparatus may include a sync data generator to generate sync data; and a sync data adder to add the sync data to an ancillary data space of a video signal. | 11-13-2014 |
20150055014 | HANDLING VIDEO TRANSITION ERRORS IN VIDEO ON DEMAND STREAMS - A system, method, and apparatus for handling transition errors is presented herein. The transition errors include handling unreported time base discontinuities during trick mode transition, miscalculated time stamps during trick mode transition, erroneous sequence end codes, and unreported broken group of picture transmission. Unreported time base discontinuities are detected by comparing the program clock reference (PCR) value of the data packet to the system time clock (STC). If the difference exceeds a predetermined threshold, the STC is set to the PCR value. Miscalculated time stamps are detected by examining the difference in PTS values between temporally adjacent data packets. If the difference is not within a margin of error from predetermined value, the PTS is disabled. Unreported broken groups of pictures are handled by skipping the first two B-frames of the first group of pictures following a trick mode transition. Erroneous sequence end codes are detected by determining whether a packet containing a sequence end code is associated with a time base change. If the packet is not associated with a time base change, the sequence end code is disregarded. | 02-26-2015 |
20150098021 | Video and Map Data Synchronization for Simulated Athletic Training - The pending disclosure includes a computer server receiving a video file and a global positioning system (GPS) data file. The video file includes video frames each having a timestamp and the GPS data file includes portions of geographic data each having a timestamp. Further, the computer server receives video user input from a user device indicating a user selection of a synchronization video frame and a GPS user input from the user device indicating a user selection of a synchronization portion of geographic data. The computer server processes the selected synchronization video frame and the synchronization portion of geographic data to determine the timestamp of both the synchronization video frame and the synchronization portion of the geographic data. Further, the computer server synchronizes the GPS data file with the video file based on the timestamp of the synchronization video frame and the synchronization portion of the geographic data. | 04-09-2015 |
