Systems and methods are presented herein that facilitate temporally synchronizing, in real time, a separately sourced high quality audio segment of a live event with a video segment that is generated by a recording device associated with a member of the audience. An A-V Synchronization Application may synchronize a video segment of a live event that is generated from a personal electronic device of an audience member with a high quality audio segment that is separately sourced and generated by professional sound recording equipment at the live event. The result of the temporal synchronization is a high fidelity digital audio visual recording of the live event. In various, the audience member may stream, in real-time, the high fidelity digital audio visual recording to an additional electronic device at a different geo-location. In some examples, narrative audio segments may be also included as part of the high fidelity digital audio visual recording.

A control device includes a data storing unit, a synchronization control unit, and a duty control unit. The synchronization control unit starts a frame period when a vertical synchronization signal is received. The frame period includes a light emission period and a light extinction period. The duty control unit controls a length of the light extinction period, based on a ratio between a total number of vertical lines in a current frame and a pre-set minimum number of vertical lines in a video image displayed on a display panel during a frame period, such that a ratio of a length of the light emission period and a length of the light extinction period during the frame period when a video image is displayed with the total number of vertical lines in the current frame is constant.

A system includes a server configured to receive a data stream and at least one client device configured to receive the data stream from the server. The server is configured to synchronize playback of a media content instance by the server, one or more of the client devices, or both, in accordance with a timestamp associated with the data stream.

A multimedia data system comprising a synchronization unit. The synchronization unit receives a demodulated bitstream, checks whether a FAW pattern corresponding to a candidate of the bitstream exists, checks whether an additional information corresponding to the candidate of the bitstream is valid when the FAW pattern exists, determines a hit weighting corresponding to the candidate according to the checking result, determines whether the hit weighting meets a criterion and outputs a synchronization signal when the hit weighting meets the criterion.

Presented herein are system(s) and method(s) for clean channel changes. In one embodiment, there is presented a method for changing a channel. The method comprises receiving a portion of a first video bitstream associated with a first channel; receiving a command to switch display from the first channel to a second channel after receiving the portion of the first video; and displaying the portion of the first video bitstream associated with the first channel after receiving the command.

Methods for removing redundancies in a video stream based on efficient pre-transmission detection of static portions of the video stream. In one embodiment supporting wireless transmission of a video stream having a series of video frames, a mathematical operation (such as a hash function, summing operation or CRC) is performed on (1) a (reconstructed) data block(s) of a video frame in order to generate a first check value and (2) a co-located data block(s) of a second, sequential video frame in order to generate a second check value. The first and second check values are compared to detect static video content in the video stream. When static video content in a video stream is detected, the static nature of the content is indicated in the compressed bit stream and the amount of wirelessly transmitted data corresponding to the static portions of the video stream may be reduced.

The present invention relates to a device able to receive packets circulating in a packet-switching network. The packets include information on a synchronization signal. The device is configured for producing first and second pulses synchronous with the synchronization signal. The first and second pulses have different periods, which are integer value multiples of the synchronization signal period.

In a coding system wherein an error correction/detection coding is combined with a synchronization recovering technique using a synchronization code, the problems of a pseudo synchronization and a step out due to error detection are solved. There is provided a coding part 212 for coding an input multiplexed code string 201 to an error correcting/detecting code comprising an information bit and a check bit, and code string assembling part 213 for inserting a synchronization code into any one of a plurality of periodically predetermined synchronization code inserting positions in the code string 201, for arranging the information bit at an optional position in the code string, and for arranging the check bit at a position other than the synchronization code inserting positions in the code string 201 to assemble an output code string 205.
