An audio/video production system facilitates professional quality image manipulation and editing using an enhanced general-purpose hardware. A program input may be translated into any of a variety of graphics or television formats, including NTSC, PAL, SECAM and HDTV, and stored as data-compressed images, using any of several commercially available methods such as Motion JPEG, MPEG, etc. While being processed, the images may be re-sized to produce a desired aspect ratio or dimensions using conventional techniques such as pixel interpolation. Frame rate conversion to and from conventional formats is performed by using the techniques employed for film-to-NTSC and film-to-PAL transfers, or by inter-frame interpolation, all well known in the art. By judicious selection of the optimal digitizing parameters, the system allows a user to establish an interrelated family of aspect ratios, resolutions, and frame rates, yet remain compatible with currently available and planned graphics and television formats.

An audio/video production system is implemented on a PC-based platform, preferably utilizing various forms of removable magnetic, optical, or magneto-optical storage media. Specially modified cameras or other sources provide digitally data-compressed audio and video program materials in two formats, a first format having a higher data-compression ratio and intended for use in off-line systems to develop edit decision lists, and a second format having a lower data-compression ratio and intended for use in on-line editing and to produce the final representations of the programs. Off-line editing decisions may thus be developed on a PC using removable storage media, and final representations of the programs may be produced on-line in accordance with stationary-head or rotary-head digital-tape-based formats, such as DAT, 6-mm or 8-mm tapes. In an alternative embodiment, automatic and unattended editing, or extended program playback of more than 40 hours duration of digital video, is available.

Methods and apparatus for broadcasting high quality audio “studio direct” with the same digital information employed in the studio by the video producer with AC-3 digital audio signals for broadcast to integrated receiver decoders (IRD). The methods and apparatus permit proper handling of AC-3 data by switching signals to encoders in response to detection of the encoded signals representing compression of the data. Control over individual data bits such as copyright bits is maintained by determining the bit status, comparing it to a preferred status, changing the status if it does not comply with the preferred status, and reevaluating cyclical redundancy check value in each data packet to avoid disruption in the data transmission. In addition, the system includes an uplink device which automatically checks, logs and reports errors in Dolby Digital AC-3 signals by a monitor which employs a processor, a digital audio card and an SMPTE timecode reader. As an option, an ethernet interface may be provided to permit AC-3 transmission to expedite storage and transmission of the audio data by media such as compact disks. The monitor employs a state machine that finds AC-3 packets, locks into the packets and detects discontinuities or loss of signal. The monitor then computes and checks the cyclical redundancy check value of the AC-3 packet found. In addition, the system enables the device to play AC-3 signals such as Dolby Digital out in sync with video signals, regardless of the storage media for the files. A sound card having an input for receiving house reference AES clock pulses enables the AES clock of the playback signal to be locked to the frequency of a production house master as a time code reader or an editor's contact closure match video and audio signals playback.

A multi-format digital video production system enables a user to process an input video program to produce an output version of the program in a final format which may have a different frame rate, pixel dimensions, aspect ratio, or any combination thereof. An internal production format of 24 fps is preferably chosen to provide the greatest compatibility with existing and planned formats associated with HDTV standard 4:3 or widescreen 16:9 high-definition television, and film. Images are re-sized horizontally and vertically by pixel interpolation, thereby producing larger or smaller image dimensions so as to fill the particular needs of individual applications. Frame rates are adapted by inter-frame interpolation or by traditional schemes, including “3:2 pull-down” for 24-to-30 fps conversions. Simple speed-up (for 24-to-25 conversions) or slow-down (for 25-to-24 conversions) for playback, or by manipulating the frame rate itself using a program storage facility with asynchronous reading and writing capabilities. The step of converting the signal to a HDTV format is preferably performed using a higher sampling clock frequency and a resizing to HDTV format frame dimensions in pixels. An integrated system having digital television standard conversion capabilities is disclosed, wherein audio/video input signals are received in high-speed serialized form, transferred to a high-speed data bus, and fed to one or more standards converters operating according to the invention, thereby providing a variety of serial or parallel digital signal outputs. The system may further include a wide-/local-area network interface, mass storage, digital effects unit and workstations for multiple users.

According to the method, when a user needs to add a dynamic paster on a first video, a target dynamic paster template selected by the user is acquired by a mobile terminal, and a target picture taken as a dynamic paster material is selected by the user from a local album; the display position and playing duration of the dynamic paster set by the user on the first video are acquired; later, the target paster and the first video are synthesized into a target video according to set parameters of the target paster and motion parameters of the target dynamic paster template, adding the dynamic paster on the existing video is realized, and dynamic effect demands of the user for the paster are satisfied; the picture material of the dynamic paster can be selected from pictures shot by the user herself/himself, and customization demands of the user for the paster are satisfied.

A portable video switching device receives video streams from a multiple number of different video capture devices located remotely and selects one of the video streams for further transmission. The portable video switching device receives video streams via wired, wireless or mobile telecommunication network connection and has video production capability to manipulate the selected video stream to add special effects, fading and the like.

This disclosure describes methods and systems for managing video frame rate at a video production site. A video processor of a first video production site may process received video frames received via a network with dynamic transmission properties. A frame rate controller may monitor at an output buffer of the site, an average rate of processed video frames received from the video processor, and may detect that the average rate of processed video frames received from the video processor has decreased to a level below a predefined output frame rate for transmitting processed video frames to a third video production site. The frame rate controller may increase a rate of video frames being provided to the video processor, to a level above the predefined output frame rate to restore the average rate of processed video frames received from the video processor, to the predefined output frame rate.

Systems and methods are described for automatically driving portions of a video production workflow according specifications governed by a data-rich storyboard. Embodiments operate in context of a novel video production workflow in which much or all of the production expertise of a traditional production workflow collaborates at a storyboard phase of the workflow to architect a single, data-rich storyboard according to concepts and rules. The rich storyboard is generated and stored in a data framework that drives specifications over the workflow in such a way that portions of the workflow can be automated and consistently repeated. For example, the rich storyboard drives generation of automated coaches for acquisition and pre-auditing of individualized story assets from storymakers. The rich storyboard can then drive automated rendering of the assets into multiple, individualized storyvine video products that each conforms to the rich storyboard concepts, rules, and specifications.
