The invention allows the user to store selected television broadcast programs while the user is simultaneously watching or reviewing another program. A preferred embodiment of the invention accepts television (TV) input streams in a multitude of analog and digital forms. The TV streams are converted to (MPEG) formatted stream for internal transfer and manipulation and are parsed and separated it into video and audio components. The components are stored in temporary buffers. Events are recorded that indicate the type of component that has been found, where it is located, and when it occurred. The program logic is notified that an event has occurred and the data is extracted from the buffers. The parser and event buffer decouple the CPU from having to parse the MPEG stream and from the real time nature of the data streams which allows for slower CPU and bus speeds and translate to lower system costs. The video and audio components are stored on a storage device and when the program is requested for display, the video and audio components are extracted from the storage device and reassembled into an MPEG stream which is sent to a decoder. The decoder converts the MPEG stream into TV output signals and delivers the TV output signals to a TV receiver. User control commands are accepted and sent through the system. These commands affect the flow of said MPEG stream and allow the user to view stored programs with at least the following functions: reverse, fast forward, play, pause, index, fast/slow reverse play, and fast/slow play.

Multimedia time warping system

In a system for distributing videos, a plurality of videos are stored on a mass storage device. Each video includes a plurality of frames of digitized video data for play-back on a viewing device. The system includes a memory buffer for storing a segment of a selected one of the videos. The segment includes a predetermined number of frames representing a predetermined time interval of the selected video. In addition, the memory buffer including a write pointer and a read pointer. Software controlled servers are provided for witting and reading video data of the selected video to and from the memory buffer, independently, at locations indicated by the write and read pointers to transfer the selected video to the viewing device.

Segmented video on-demand system

A display apparatus includes an image processor which processes an image to display an image content; a display unit which displays thereon an image content that is processed by the image processor; and a controller which displays a user interface (UI) menu including a plurality of UI items to search the image content, as one of a two-dimensional (2D) layout by which the plurality of UI items are arranged in a 2D manner, and a three-dimensional (3D) layout by which the plurality of UI items are arranged in a 3D manner , and changes displaying the one of the layouts to display the other of the layouts according to a user's command while maintaining a continuity of the arrangement of the plurality of UI items. Accordingly, search for an image content can be efficiently performed by using a UI menu.

Display apparatus and control method thereof

An identification instrument (10) such as a pocket sized card wich includes both human recognizable (12, 14, 18) and machine readable indicia (30). The human recognizable material may be any combination of photographs (12), graphical or textual information (14, 18), with the machine readable section (30) encoding any or all of the human recognizable areas in their entirety. When the card is presented for verification, the machine readable section is scanned (figure 2b), decompressed and/or deciphered and compared to the database used to generate the human recognizable section or sections. Only with a substantial matching of the information may the card and its user be authenticated. Preferably, a Symbol Technologies compliant two dimensional bar code is used as the machine readable encoding format. Multiple levels of encryption and decryption are also described in conjunction with enhanced security.

System for producing a personal id card

An apparatus and method for adding information to image data of a multicolor image and a monochromatic image includes the performing of a dispersion conversion on the spectrum of additional information to be added to the image data by multiplying a code sequence of a PN sequence generator by the additional data which is inputted from an input terminal and converted into serial data in a P/S converter. At this time, the data sequence transmitted from an image signal processor to a printer engine 107 is converted by a scan converter to correspond to the spatial axis for dispersion. The converted data sequence is added to the output from an adder by another adder 110, and reconverted to the original scan by a scan inverter.

Image processing apparatus and method for synthesizing first and second image data

A video printer is disclosed. An input video signal is converted into a digital signal and stored in a memory. The write/read operation and memory addresses of the memory are controlled by a memory control unit. The signal read out of the memory is converted into print data, and an image is printed by a printer. The print data and the printing operation are controlled by a print control unit, and at least a part of the memory areas of the memory is controlled in the write operation by an area control unit.

Video printer with separately stored digital signals printed in separate areas to form a print of multiple images

An apparatus for driving a brushless motor, in which a ripple appearing in the rotation torque of the motor is cancelled by driving the motor with a signal current whose phase is opposite to that of and which has a waveform symmetrical with that of the torque ripple waveform, so that the motor can rotate accurately without any speed variation. In order to obtain such a signal current waveform, counter-electromotive forces induced in the stator coils of the motor are detected, and the level of the signal indicative of the detected counter-electromotive forces is controlled depending on the load and rotation speed of the motor to provide a control signal for controlling the motor drive current.

Apparatus for driving brushless motor

White balance adjusting apparatus for controlling the levels among RGB signals of the video signals and adjusting the white balance of the video image is provided in a color video printer apparatus which receives the video signals and prints out. Prior to color printing, the white balance is adjusted, thereby enabling a good color reproduction to be obtained.

Signal processing circuit including a white balance adjusting circuit in a color video printer apparatus

During the playback operation for freezing and storing a specific frame of a picture in a memory and thereafter printing the frame, the recording medium is turned reversely for a prescribed amount according to an instruction from a printer in response to the entry of the freeze command in order to accurately search the frame at the entry of the freeze, and thereafter the recording medium is played back in normal mode. The amounts of reverse turn and the successive forward turn in normal playback are counted and compared, and when the difference has become a prescribed value, a freeze signal is produced and the frame of the picture selected by the freeze command is stored in the memory and printed when required. This control method for use in a video print system is designed so that the recording medium is turned reversely for a prescribed amount according to an instruction from the printer and then stopped until the next command is entered.

Method and apparatus for controlling a video signal print system

An auto-tracking method and apparatus of a helical scan type magnetic recording/reproducing apparatus wherein envelope levels of reproduced signals are detected and the running phase of a magnetic tape is controlled so that the envelope level of the reproduced signal becomes maximum after detection is effected roughly and then finely, thereby allowing a video head to scan a track on the magnetic tape.
