Abstract

A multi-format digital video production system is capable of maintaining full-bandwidth resolution of subject material while providing professional quality editing and manipulation of images intended for digital television and other applications, including digital HDTV programs and specialized video monitoring applications. This allows emerging broadband video transmission media, including Internet broadcast schemes, to overcome existing technology limitations. The approach facilitates high-quality/large-screen video production and monitoring through the use of conventional broadband channels, including those which currently only exhibit bandwidths on the order of 4 Mbps. In formats utilizing substantially 24 fps progressive scan multi-format system, direct streaming is made possible from HDTV (16:9) high-quality data, thereby expanding market applications which require these higher levels of resolution, bits per pixel, and so forth. For example, these formats are employable to enable a video surveillance system to transmit images and video streams to a remote viewing device.

Claims15

Dependent claims

A method for providing remote access to a video surveillance system comprising:

converting, at a computing device, a first plurality of video streams into a selected video format in a particular resolution using a given set of temporal and spatial parameters associated with images in each of the first plurality of video streams, wherein each video stream comprises a stream of images captured at one of a plurality of different video sources, wherein each of the plurality of different video sources comprises a camera of the video surveillance system;
contemporaneously storing at least a subset of the converted video streams in a storage device in a network environment;
receiving, from a remote computing device remotely located from the video surveillance system, a request to receive one or more specific video streams;
transmitting one or more of the converted video streams that includes a given video stream, either directly from one or more of the plurality of different video sources or from the storage device, outbound onto a network to be delivered to the remote computing device via a communication channel and in the selected format in the particular resolution, wherein the selected video format is a progressive video format which has a frame rate of less than substantially 24 frames per second, wherein the communication channel traverses at least one external broadband connection between the remote computing device and the network environment;
and
displaying, at the remote computing device, a second plurality of video streams in separate windows using another set of temporal and spatial parameters to display images of the second plurality of video streams in each of the separate windows, wherein the second plurality of video streams includes the given video stream.

A method for providing remote access to a video surveillance system, comprising the steps of:

receiving video images at a personal computer based system from a plurality of video sources, wherein each of the plurality of video sources comprises a camera of the video surveillance system;
displaying one or more of the received video images in separate windows on a personal computer based display device, using a first set of temporal and spatial parameters;
converting one or more of the video source images into a selected video format in a particular resolution, using a second set of temporal and spatial parameters associated with images;
contemporaneously storing at least a subset of the converted images in a storage device in a network environment;
providing a communications link to allow an external viewing device to access the storage device;
receiving, from a remote viewing device located remotely from the video surveillance system, a request to receive one or more specific streams of the video images;
and
transmitting, either directly from one or more of the plurality of video sources or from the storage device outbound on the communication link to the remote viewing device, and in the selected video format in the particular resolution, the selected video format being a progressive video format which has a frame rate of less than substantially 24 frames per second using a third set of temporal and spatial parameters associated with images, a version or versions of one or more of the video images to the remote viewing device, wherein the communication link traverses at least one external broadband connection between the remote computing device and the network environment.
