Abstract: A communication protocol over the serial bus allows a peripheral device to control the flow of data between a host computer and the peripheral device so as to maintain synchronization to a periodic reference signal. The protocol involves transferring flow control messages between the peripheral device and the host computer, allowing the peripheral device to control how and when the host computer sends the uncompressed audio and video data.

Abstract: A moving picture recording device includes a random-access, computer-readable and writable storage medium to provide non-linear access to recorded clips. The device provides digital capture of both video and audio information. Multiple data paths are provided to allow recording to and playback from the storage medium. Lists are maintained to manage recorded clips and edited events. An outtake list of deleted clips is also maintained. An event list includes a list of video events including clips from the storage medium as well as other video sources including a camera or external video. With switching circuitry, recorded clips can be viewed during editing while live images are output to a program output. An editing interface includes dedicated keys for performing standard recording functions as well as a display with associated input keys having adaptive functions. The textual display indicates the function currently associated with the input key.

Abstract: A digital media recorder including a video camera digitizing circuitry and a digital computer readable and writable random access medium, such as magnetic or optical disk, in which sequences of digital still images are stored directly on the recording medium. Audio recording capabilities may also be provided. This system eliminates the need for video tape for recording video information, thereby providing the capability for a purely digital video system for capture, editing and playback.

Abstract: A catalyst precursor composition comprising: a) a source of chromium, molybdenum or tungsten; b) a first ligand having the general formula (I); (R1)(R2)P—X—P(R3)(R4)??(I) wherein: X is a bridging group of the formula —N(R5)—, wherein R5 is selected from hydrogen, a hydrocarbyl group, a substituted hydrocarbyl group, a heterohydrocarbyl group, a substituted heterohydrocarbyl group, a silyl group or derivative thereof; at least three of R1 to R4 are independently selected from optionally substituted aromatic groups, each bearing a polar substituent on at least one of the ortho-positions; and optionally one of R1 to R4 is independently selected from hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl and substituted heterohydrocarbyl groups with the proviso that when the group is aromatic it does not contain a polar substituent at any of the ortho-positions; c) a second ligand having the general formula (II); (R1?)(R2?)P—X?—P(R3?)(R4?)??(II) wherein: X? is a bridging group as defined for X of the fi

Abstract: A portable moving picture recording device includes switching control to enable multiple data flow configurations. Two output encoders receive either composite or component digital video signals. The component video signals can come from one of three sources: decoded composite video, component video, and a random-access storage device. Inputs to a composite video analog-to-digital converter and a genlock decoder may be switched between at least two outputs, including a camera video and external video sources. The digital component signal may also be recorded onto the random access recording medium. These data paths are provided in a portable moving picture recording device, in combination with some editing capability.

Abstract: A communication protocol over the serial bus allows a peripheral device to control the flow of data between a host computer and the peripheral device so as to maintain synchronization to a periodic reference signal. The protocol involves transferring flow control messages between the peripheral device and the host computer, allowing the peripheral device to control how and when the host computer sends the uncompressed audio and video data. The audio and video data may be sent as separate streams. Using the IEEE-1394 protocol, the flow control messages are sent using an asynchronous protocol, whereas uncompressed video and audio data are sent using an isochronous protocol. Streams of uncompressed video and audio data are transferred from the host computer over a serial bus to the peripheral device, where the peripheral device performs operations on the data such as encoding the data into a standard format, such as DV and MPEG, or generating an analog video signal.

Abstract: Two channels of output of sequences of digital still images are input to a DVE system which has pipelined memory circuits rather than frame buffers. The DVE system includes a DVE unit which performs arbitrary three-dimensional, digital video effects on the two channels of input to provide a composite output sequence. The DVE system thus operates on sequences of digital still images rather than video signals. The DVE system is also adapted to prevent output upon receipt of a control signal, which may indicate that an output pipeline is full. The DVE system also provides a control signal to prevent input when it cannot receive input or it is not providing output.
