A workstation for processing and producing a video signal comprises a video input system, a video graphics processor, and a video output system. The video input system may comprise a video input module, a first video pipeline, and a second video pipeline. The video output system may comprise a receiver, a video pipeline and a video output module. In addition, the video input system may comprise a video input module having a specific configuration and a video processing module having a connector for coupling the video input module, the specific configuration of the video input module setting the characteristics of the video processing module. The video output system may comprise a video processing module having a connector for coupling a video output module and a video output module having a specific configuration, the specific configuration of the video output module setting the characteristics of the video processing module.

Workstation for processing and producing a video signal

An insertion apparatus receives a byte value from a signaling channel, locates a particular unused byte location within an overhead portion of a synchronous optical network (SONET) frame, and inserts the byte value from the signaling channel into the particular unused byte location. An extraction apparatus receives a synchronous optical network (SONET) frame, locates a particular byte location within an overhead portion of the SONET frame that is unused for SONET purposes, and captures a byte value from the particular byte location, wherein the byte value comprises a signaling channel.

Utilizing available SONET overhead bytes for additional signaling channels

A method and apparatus for producing video signals comprises a receiver for receiving a video signal, a video pipeline for post-processing the received video signal, the video pipeline producing a post-processed video signal, and a video output module for converting the post-processed video signal, the video output module producing a formatted video signal. The video output module may further comprise an ancillary data injector, the injector inserting ancillary data into the post-processed video signal. Also, the video output system may further comprise a generator locking device or the video input module may include a generator locking device.

System and method for producing a video signal

A method and apparatus for video signal frame rate matching using three buffers. The method and apparatus reads frame data out of the third buffer. At substantially the same time, the method and apparatus fills the first buffer with the next sequence of frame data and then fills the second buffer with the next sequence of frame data, continuing to alternate the fills between the first buffer and the second buffer until all of the frame data has been read from the third buffer. Next, the method and apparatus determines which of the first buffer or second buffer has been filled with the most current and most complete frame data. Last, the method and apparatus reads the frame data out of the determined buffer.
