| 121 | Distribution of television signals to workstations | US150947 | 1993-11-12 | US5642151A | 1997-06-24 | Wendi L. Nusbickel; Ira H. Schneider |
| Digital video data (such as full motion video and audio) is distributed over a computer network to workstations by an analog video server. The network carries digital network signal traffic. The analog video server retrieves video data from a storage device. The analog video server then decompresses the digital data and converts it into an analog signal. The analog signal is shifted to a bandwidth (such as television channels) that is different from the bandwidth of the network signal traffic, and then combined with the network signal traffic to be distributed over the network. At a workstation, the analog signal is split off of the network signal traffic and provided to a display. Plural workstations can display the same analog signal. Schedules for broadcast times are provided on the network to the workstations. Plural channels in the analog signal bandwidth can be utilized to simultaneously broadcast plural analog signals to the workstations. | ||||||

| A computer workstation receives multiple audio input streams over a network in an audio conference. The audio input streams are kept separate by storing them in different queues. Digital samples from each of the queues are transferred to an audio adapter card 28 for output. A digital signal processor 46 on the audio adapter card multiplies each audio stream by its own weighting parameter, before summing the audio streams together for output. Thus the relative volume of each of the audio output streams can be controlled. For each block of audio data, the volume is calculated and displayed to the user, allowing the user to see the volume in each audio input stream independently. The user is also provided with volume control for each audio input stream, which effectively adjusts the weighting parameter, thereby allowing the user to alter the relative volumes of each speaker in the conference. | ||||||

Systems and methods sell a sound file to a user of a digital audio workstation (DAW). A sound vendor receives the sound file from a sound creator and analyzes the sound file to automatically determine a beats-per-minute value and a musical key value. The sound file is stored, in association with the beats-per-minute value and the musical key value, within a database of the sound vendor. A web interface is generated to interact with the user to receive a search request defining at least one of the beats-per-minute value and the musical key value. The sound file is selected from the database based upon the search request, a financial agreement between the user and the sound creator is completed for sale of the sound file to the user, and the sound file is sent to the DAW. |

| 125 | METHOD, SERVER AND CLIENT APPARATUSES FOR TRANSFERRING HIGH RESOLUTION MULTIMEDIA DATA IN A HIGH SPEED NETWORK | PCT/EP2008/061633 | 2008-09-03 | WO2009037113A1 | 2009-03-26 | AUST, Andreas; SIEMENS, Eduard; GLÄSER, Frank; KUBSCH, Stefan; KÖHLER, Ralf; BROCKE, Jens |
In video production sites, video material is stored on video servers in digital form. High speed networks are available for transferring video content from the video servers to workstations for post-processing like video editing, colour management etc. Most networks and a lot of software for post-processing are available for exchanging data with Internet protocol. Extensions for the RTP protocol are available for transporting high definition video/audio data based on an Internet Protocol stack. The invention enables the overall control of the data streaming by setting two incompatible flags (405, 406) in one and the same RTP packet without the need of a further extension of the RTP protocol. In one example the end of a data stream is signalled by setting the frame begin plus frame end flag (405, 406) in the packet transporting the last part of the last DPX frame in the stream. |

| The present invention provides an intelligent, digital, modular remote target device management system for coupling a series of remote target devices to one or more user workstations to allow each user workstation to selectively access and control one or more remote target devices. The target device management system incorporates a centralized switching system that receives keyboard, cursor control device, audio, and input/output module device signals from the user workstation and transmits and applies the signals to the remote target device in the same manner as if the keyboard, cursor control device, audio input source, or input/output module device of the user workstation were directly coupled to the remote target device. Also, the remote target device management system digitally transmits the signals. | ||||||

| A communication system includes a digital network and an audio network such as a telephone system. An audio network server communicates with client work stations in the digital network and with the telephones in the telephone system. The audio network server stores, and plays back, digital representations of voice objects from, and to, a telephone handset. An instruction set accessible from the digital network controls operation of the audio network server and thus the telephone system to record and play back audio information stored on the audio server. The communication system may also include a caching capability to temporarily store compound documents or component objects in a media presentation server. | ||||||

| <P>PROBLEM TO BE SOLVED: To synchronize playback among systems in a multimedia system. <P>SOLUTION: In the system 100, one or more digital audio systems 102, such as, a digital audio workstation, and one or more digital video systems, such as a video server, are interconnected through a computer network. A communication protocol among the systems using the computer network enables the systems to play back in synchronization. The communication protocol defines several states for connections between systems. In particular, two systems may be disconnected, connected and unlinked or connected and linked. Each system transitions through defined state changes that are caused by a sequence of commands in the communication protocol, called a play start sequence, to initiate synchronized playback. <P>COPYRIGHT: (C)2009,JPO&INPIT | ||||||

| 140 | Digital customized audio products with user created data and associated distribution and production system | US593295 | 1996-01-29 | US5592511A | 1997-01-07 | Neil C. Schoen; Wendy A. Schoen |
| A system for creation of user-selected customized audio products, defined as a plurality of songs from different recording artists recorded on a single compact disc (CD) or digital audio tape (DAT) cassette, at record store/distributor locations utilizing a digitized, central database with production hardware at distributor sites. Customized products consist of CD ROM or digital audio tapes (DAT) with music or voice content selected from large digital database, and are written at local workstations at distribution centers (such as record stores) which are connected by a high-speed communications network. The system records costs of the digitized audio (e.g., royalties for individual songs) for billing purposes, as well as producing descriptive material (contents, background information, and graphics for labels, etc.). Data transfer and production is faster than real-time, and thus will be a significant improvement and will tend to reduce current analog hardware-to-hardware transfer ("pirating") which violate copyright laws and is unauthorized. The system consists of integrated, state-of-the-art digital databases, communications networks, computer workstations, and unique workstation processing software, and provides an innovative product/service (individual customized albums or audio data compilations) which currently do not exist. | ||||||
