    摘要： A digital video recorder employing standard hard disk arrays employs a caching system to enable continuous video data to be supplied to and provided from the standard disk drives which may not be adapted for continuous data stream operation. The system is implemented as an array of disk drives and includes cache management functions for governing disk read and write operations. A predictor enables the cache to predict disk reads and disk writes and to maintain the cache based on the predictions. Redundancy enables playback in the event of failure of a drive in the array and also provides improved playback data retrieval time.

    摘要： A simple compositing system for combining sequences of images, including graphics and video images, records the sequences onto a disk recorder. A frame from each sequence in turn is processed by a digital picture manipulator channel and stored in a respective frame store. Once one frame from each sequence is processed and stored, the frames from the frame stores are combined in a video combiner to form a composite frame, which is read back into the disk recorder. All of the frames of the sequences are combined in this manner to form composite frames, the totality of composite frames producing a final composite image sequence stored in the disk recorder. The final composite image sequence is then transferred to an output device in real time.

    摘要： A mix/effect status display provides simultaneous information about each keyer and bus associated with a mix/effect bank without consuming the real estate required for the conventional button/knob per function approach. Also the sources coupled to the M/E buses are shown together with the transition status if a transition is in progress. A switcher working buffer has information about the switcher control panel controls, and transfers that information that relates to the mix/effects banks to a mix/effects status display driver. The driver provided the mix/effects status display with a row for each bus associated with the M/E and all information related to the source coupled to that bus together with information about the M/E operating mode and transition status, type and interval. Thus an operator has a complete picture of M/E status without requiring substantial additional real estate on the switcher control panel.

    摘要： A mix-effect bank architecture for a production video switcher has multiple programmable outputs, the outputs being determined by a selected operational mode including split, programmable clean feed and mix minus modes. Four keyers with video and key signal inputs produce four outputs. The outputs are selectively routed to four corresponding inputs of four mixers, which mixers also have two pairs of background/utility video inputs. The four mixers provide four outputs which are determined by the selected operating mode. A pair of background video signals may be provided to all of the mixers to provide programmable clean feed outputs, or the pair of background video signals and a mix minus pair of background video signals may be provided to the mixers to provide mix minus outputs, or a primary set of background video signals may be provided to two mixers and a secondary set of background video signals may be provided to the other two mixers for the split mode.

    摘要： An improved video production architecture adds an additional transition element for controlling external devices in synchronism with a given transition so that the transition is treated like a simple mix or wipe. The additional transition element is a “Trigger” function that has a value indicating when during the given transition the external device is activated. The trigger function, device controlled and trigger value are set up during preconfiguration of an effect in an effects memory. When the effect is recalled, if the Trigger function is activated on a switcher control panel, then the external device is activated at the time during the given transition specified by the trigger value.

    摘要： A method for synchronization of a digital audio signal sampled at a standard audio frequency with the corresponding digital video signal sampled at a standard video frequency associates an integer number of samples of the digital audio signal with each video field of the digital video signal. The number of audio samples per video field is determined by the audio sample rate rounded up to the nearest integer. Every N video fields where the number of digital audio samples is an integer value, the digital audio signal is resynchronized with the digital video signal by repeating the digital audio samples at the end of video field N that correspond to video field N+1. At reception the same digital audio samples are skipped at the end of video field N.
