The present technology relates to a transmission device, a reception device, a transmission system, and a transmission method capable of improving transmission efficiency of subdata added to main data. A transmission device includes a frame sequence number setting unit that, on the basis of a frame number indicating an order of a subframe in a main frame, assigns to the subframe a frame sequence number indicating an order of the subframe in a frame sequence including a plurality of the subframes, and a multiplexing unit that arranges a data packet at a predetermined position in the subframe on the basis of the frame sequence number. The present technology can be applied to a CCU, for example.

Transmission device, reception device, transmission system, and transmission method

An image display apparatus includes an active-period interlaced-to-progressive (IP) converter configured to convert active periods (video periods) included in interlaced signals into progressive signals; a blanking-period IP converter configured to convert blanking periods included in the interlaced signals into progressive signals; a multiplexer configured to generate and output display data including both the progressive signals associated with the active periods and the progressive signals associated with the blanking periods; and a display unit configured to display the data output from the multiplexer. The blanking-period IP converter is configured to generate the progressive signals associated with the blanking periods by executing IP conversion in which values copied from data included in the interlaced signals or values corresponding to black pixels are set as pixel values of an interpolated field not included in field data of the interlaced signals.

The number of decoders necessary for &#xbd;-speed reproduction is reduced and deterioration in resolution is restricted without necessitating an interpolation processing. First digital image signals and second digital image signals having a different frame rate from that of the first digital image signals are compressed on the basis of one same encoding system. Based on a method of rearranging macro blocks of the second digital image signals, the macro blocks of the first digital image signals are rearranged, so that the respective digital image signals compression-encoded and outputted can have macro block layouts equivalent to each other.

Apparatus for adjusting a digital signal which is subjected to analog processing after being reproduced from a record medium includes a digital test signal source, a loop including DAC and ADC for circulating the digital test signal therethrough a predetermined number of times, a detector for detecting changes in the test signal after having been circulated through the loop, and adjustment means having adjustment values set in response to the detected changes so as to adjust predetermined characteristics of a digital video signal that subsequently may be reproduced from the record medium, thereby minimizing changes and degradations in the reproduced digital video signal that otherwise would be caused by the analog processing.

Multi-loop testing apparatus with means for adjusting a reproduced video

Apparatus for adjusting a digital signal which is subjected to analog processing after being reproduced from a record medium. A prerecorded digital test signal is reproduced and written to a field memory which, during a normal playback mode, is used to store the digital video signal that may be reproduced. A loop, which is opened during the normal playback mode, includes DAC and ADC for circulating the digital test signal therethrough a number of times and is coupled to the field memory to receive the stored test signal. A detector detects changes in the test signal after having been circulated through the loop, and these changes are used to establish adjustment settings for adjusting the digital video signal during a playback mode.
