Embodiment Construction

[0020] The present invention provides systems and methods for fully embedded audio switching capabilities for serial digital video routers. Serial digital video router switching matrices can provide fully embedded audio switching independent of video switching. The router can be used in high-definition and / or standard-definition applications. By providing completely independent switching of the audio signals included in the serial digital video bitstream, cost and complexity are reduced and greater flexibility is achieved in the selection of inputs and outputs of the system.

[0021] It should be understood that the invention is described in terms of television installations; however, the scope of the invention is much broader and may include any audio / video system that receives from one or more sources to be routed to one or more destinations multiple audio and video signals. Content may be received by any method, eg, transmission over a network such as telephone, cable, co...

Abstract

The present invention provides an equipment which includes a separator for selectively separating audio from input signals including video with audio, a switcher for selectively transferring the input signals to at least one output, a multiplexed path for sending the separated audio signal to the at least one output, the at least one output being configured for selectively directing the input signals and separated audio signals.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from pending US Provisional Application Serial No. pending, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates generally to switching systems, and more particularly to systems and methods including a serial digital video router switching matrix with fully embedded audio switching capability independent of video switching. Background technique [0004] Routing switchers may also be called signal selectors, audio / video (AV) selectors, or simply routers. A standard routing switcher can have multiple video and audio signals from multiple sources (such as VCRs, media servers, satellite receivers, etc.) connected to the router's inputs. The output of the router can lead to one or more destinations, such as video tape recorders, video / audio mixers, video / audio monitors, etc. The user can select which input to connect to w...
