An inexpensive audio and video processing system (1) for combining animated object images with live video (28) with the addition of a combined audio capability (12) is disclosed. The system (1) includes a video processor system comprising a real-time object (RTO) processor (10) for rendering object-based graphic images, a video input means (30,27) for receiving a first video signal (28), at least one colour mixing and generation device (13) arranged to combine said first video signal (28) with image data (24) rendered from the RTO processor (10) to provide a second video signal and a video output means (38) for outputing same.
A television with hard disk drive comprises an analog video source which may be digitized and stored on a hard disk drive for later playback wherein the stored video data is capable of being played back at a rate slower, faster, or the same as the original analog video signal, thereby providing a viewer with flexibility in viewing a program. Also disclosed is a method for viewing a television program or other video material employing the apparatus according to the present invention.
A multiplexing apparatus for use in a computer system is disclosed. The multiplexing system is typically designed for multiplexing various sources of video signal inputs for subsequent processing. The multiplexing apparatus includes at least one analog video input connector, but preferably has more than one, a programmable signal connector, and a plurality of video output connectors. The programmable signal connector couples to the analog video input connector and selectively multiplexes the analog video input signal. The plurality of video output connectors are further coupled to the programmable signal connector, and they receive the multiplexed video signal from the analog video input connector for processing through at least a first video stream. Additional video streams are also possible for processing for a single input signal.
An audio recorder with retroactive storage capability operates under control of a sound responsive switch to enter signals representative of the instantaneous amplitude of sound signals received by a microphone into a first-in first-out memory. When the memory is filled, digital signals representative of newly recorded sound supplant the oldest signals in the memory. An operator listening to the sound may retroactively capture signals representative of the most recently occurring sounds against erasure by depressing a pushbutton. Circuitry responsive to the resulting signal removes the most recently generated sound signals from the first-in first-out queue so that they may be later recalled to reproduce the sounds.
A device for performing single precision floating point arithmetic. The device includes a shared operand generator that receives an operand and outputs a result that is a fixed function of the operand. It also includes an arithmetic circuit comprising a plurality of multiply circuits that calculate partial products of a first and second operand and the result of the shared operand generator. It also includes circuitry to calculate the sum of the partial products and a third operand to produce the arithmetic result.
An electronic system, an integrated circuit and a method for display are disclosed. The electronic system contains a first device, a memory and a video/audio compression/decompression device such as a decoder/encoder. The electronic system is configured to allow the first device and the video/audio compression/decompression device to share the memory. The electronic system may be included in a computer in which case the memory is a main memory. Memory access is accomplished by one or more memory interfaces, direct coupling of the memory to a bus, or direct coupling of the first device and decoder/encoder to a bus. An arbiter selectively provides access for the first device and/or the decoder/encoder to the memory. The arbiter may be monolithically integrated into a memory interface. The decoder may be a video decoder configured to comply with the MPEG-2 standard. The memory may store predicted images obtained from a preceding image.
