A method is disclosed for compressing a frame of data representing parameter values, a time at which each parameter value was recorded, and an orientation of a sensor at the time each parameter value was recorded. Generally the method includes performing a two-dimensional transform on the data in the orientation domain and in a domain related to the recording time. In one embodiment, the method includes calculating a logarithm of each parameter value. In one embodiment, the 2-D transform includes generating a Fourier transform of the logarithm of the parameter values in the azimuthal domain, generating a discrete cosine transform of the transform coefficients in the time domain. This embodiment includes quantizing the coefficients of the Fourier transform and the discrete cosine transform. One embodiment of the method is adapted to transmit resistivity measurements made by an LWD instrument in pressure modulation telemetry so that while-drilling images of a wellbore can be generated. The one embodiment includes encoding the quantized coefficients, error encoding the encoded coefficients, and applying the error encoded coefficients to the pressure modulation telemetry.

Communication and resolution of potential recording conflicts are disclosed. In one aspect, a request for recording a new program is received, and recording schedules are examined to determine whether another program had been previously scheduled for recording at the same time. If so, a display that illustrates and allows resolution of the conflict is automatically provided. In another aspect, a recording queue and an exception list provide efficient identification of conflicts and management of scheduled recordings. The recording queue lists each program to be recorded, and the exception list identifies conflicting pairs in the recording queue and indicates which item in each pair is respectively retained (preempting) and deferred (preempted). Canceling a preempting recording removes it from the recording queue and the conflict from the exception list to reinstate a preempted program. Channel guides that illustrate recording conflicts are also provided.

A video surveillance system which includes at least one field recording site and at least one remote viewing site linked by a communication channel of the internet. The field site locates a video surveillance recorder which archives a compressed digital video signal from a video source to a digital memory. Similarly, data associated with the video signal is archived to a digital memory. The archived video signal is stored in file segments associated with the times they are recorded. The system further provides a compressed real time video signal. The video surveillance system also includes a server interface to the internet whereby the field site may be controlled to provide the video and data information to a user at the remote site. User commands may be communicated from the remote site to the field site to transfer either the real time video signal, the archived video signal or the archived data signal. The selected signal is then displayed on a video monitor of the remote viewing site. Specific times of the archived video signal or the archived data signal may be viewed by selecting from a list of files archived on the digital memory. The surveillance system may have more than one field site recorder and/or more than one remote viewing site.

Timers of a plurality of slave units are synchronized with a timer of a master unit by a) sending a synchronization message on the first network by the master unit, which contains a time measurement of the master unit and a time scale, to the slave units; b) at each slave unit, forming the difference between a time measurement recorded in the slave unit and the time measurement received by the master unit, and correcting the current time measurement of the slave unit by this difference, and, at each unit, the recording of a time measurement upon receipt of the time scale; c) at the master unit, inserting the recorded time measurement into a subsequent synchronization message.

The invention provides an editing system for editing and combining media material into a resulting media composition. The media may be film or video based material, and also may include audio material. The video may adhere to either NTSC or PAL timing. In response to editing instructions, an Edit Decision List (EDL) is produced that specifies the material that makes up the edited composition, and the order of presentation of this material in the output composition. The EDL specifies the input clips that are taken from the source material using source timecode and similarly defines the output order again according to a new time code, the record time code. The editing system produces an extended EDL that facilitates the downstream processing (after the editing has been completed) for post production tasks requiring the need to know accurately where edit points occur.

A broadcast program recording overrun and underrun scheduling system provides a system for adjusting the start and end times of a broadcast program's recording schedule that has a predetermined start and end broadcast time. An on screen program guide is displayed to the viewer via a monitor or television and lists the predetermined scheduled broadcast times and channels of a plurality of broadcast programs. The viewer selects a particular broadcast program to record from the program guide using a remote input device. The invention schedules the broadcast program to be recorded by inserting the program's information such as program identifier, start and end times, and storage duration into a recording schedule database. The invention allows the viewer to adjust the scheduled start and/or end recording times for a broadcast program by specifying the time increment to add or subtract from the start and/or end recording times of a specific program or series of programs. The invention adjusts the recording schedule to the viewer's modifications. Broadcast programs are recorded onto a persistent storage device when the recording schedule indicates that it is time to do so. The viewer is allowed to adjust the end recording time of a program while the program is being recorded. The viewer can randomly access the recorded programs on the persistent storage device for play back.

The method and a system is for locating and recording time-limited signal sequences in media channels that may contain undesirable signal components, e.g., recording music in radio transmissions. The signals are continuously buffered in a memory. The user identifies a desired source material. Out of this desired source material a section may be taken as a search key. The device may also select search keys automatically. If a second instance of the search key is detected, signal sequences that in time are connected to the search keys are compared. The signal sequences that by comparison are substantially identical are identified as belonging to the same, wanted, source material. The next step is an iteration of the above procedure results in a longer and higher quality segment of source material than the initial common segment.

The invention provides a continuous data protection method. Data can be recovered to any time point; data mounting in a short time can be realized; and the fast verification, write-in and immediate use of the data are realized. The method comprises the following steps that: initialization synchronization is executed at first; the initial state of production host block equipment is synchronized to a backup host; meanwhile, a data variation capturing module is started for capturing the data variation and transmitting the data variation to the backup host; the data variation is written into a mirrored volume; original data of a data variation address is written into a journal volume; the timestamp, the offset, the length and the storage address are recorded; and the recording of any data variation is realized. The reconfiguration of a virtual volume is used; the actual data access is redirected to the mirrored volume, the journal volume and a write time volume through a virtual volume index block; and the data read-out and the data write-in are realized. The data recovery is realized by using data read-out. Obsolete data can be deleted only through finding and deleting all of the journal volume and journal volume metadata files with the ending timestamp before the time point.
