摘要:
A source device transmits an output format notify message for video data to a sink device before transmitting the video data to the sink device, the output format notify message including a 3D field storing data for identifying whether the video data to be transmitted is two-dimensional video data or three-dimensional video data transmitted using frame packing. In response to this, the sink device identifies a type and a format structure of the video data, and decodes the received video data based on the identified type and format structure of the video data.

A sink device transmits a video information message to the source device, the video information message including video format information identifiers for identifying video formats supported by the sink device, which are selected from among a plurality of video format information identifiers for identifying video formats each including a resolution of the video data and a type of the video data, and a three-dimensional transmission method for three-dimensional video data when the type of the video data is the three-dimensional video data including first and second video frame data.

This invention presents an apparatus for composing an ATM wrapper transmission block capable of handling plural pieces of program information transmitted in SDTI or IP packet commonly by a low overhead. Since the ATM wrapper transmission block conforms to both AAL1 system and AAL5 system, sequential connection is possible by changing over the AAL1 transmission and AAL5 transmission in the ATM wrapper layer. Further, by the AAL5 system, live transmission output of minimum transmission delay, and contribution output free from error can be issued at the same time, and therefore the error is corrected by referring to the reception data in the former, and the error is corrected by re-sending the error position data in the latter.

A controller issues a command to an HDD interface to transfer AV data stored in HDDs to a memory. The HDD interface, in compliance with the command, transfers the AV data stored in the HDDs to a memory mapped on a bus. A memory controller reads the AV data out of the bus, and writes the AV data into the memory. The controller outputs the address of the AV data to be outputted to the memory controller. The memory controller reads out the AV data of the designated address, and outputs them to an AV data output interface. And the AV data output interface outputs the AV data. The controller issues a command to the HDD interface memory to record the AV data stored in the memory into the HDDs. The HDD interface, in compliance with the command, reads the data out of a memory mapped on the bus, and stores them in the HDDs. The memory controller reads the AV data out of the memory, and outputs them to the bus. At the same time, the controller designates to the memory controller the address in the memory into which the AV data inputted from the AV data input interface are to be written. The memory controller reads the AV data out of the AV data input interface, and writes them into the designated memory. By accomplishing this series of actions in synchronism with the frame period, AV data are stored in the HDDs, and also AV data stored in the HDDs are outputted.

A position control system is disclosed for positioning a stepping motor to a target position according to a closed loop control system. The closed loop control system controls the position of the stepping motor according to a current position signal outputted from an encoder operatively coupled to the stepping motor. Furthermore, circuitry is provided for correcting electrically a torque angle error of the stepping motor caused by a positional error between the stepping motor and the encoder due to a mechanical mounting error of the encoder, to thereby drive the stepping motor at a torque angle maintained at the most desirable range.

The present invention provides a novel camera apparatus which can be discretely split into two parts; a lens barrel unit and a lens-barrel-support unit which allows the lens barrel unit to freely turn its direction. A built-in angular rate detector detects a swinging movement of the lens barrel unit, whereas a position detector detects a position relationship between the lens barrel unit and the support unit. An operator unit storing programs controls a drive operation of an actuator that generates a specific amount of torque between the lens barrel unit and the support unit to reduce an output from a system controller unit so that swinging symptom of video picture caused by the swinging movement of the video camera can be eliminated. In addition to this primary function, the operator unit also executes its secondary function, in which the operator unit first detects intention of a camera operator by identifying a varied position relationship between the lens barrel unit and the support unit when one intentionally changes an aimed direction of the video camera and then the operator unit controls the driving of the actuator so that the lens barrel unit can correctly face the aimed direction.
