A method and apparatus for generating an encoded data stream representing a number of pictures or frames and having a number of layers including a picture layer in which time code information attached to the original data is described or inserted therein for each picture. Such time code information may be inserted into a user data area of the picture layer of the encoded data stream.

Encoded stream generating apparatus and method, data transmission system and method, and editing system and method

The present invention makes it possible to efficiently transmit data for statistical multiplexing which is required for control using statistical multiplexing. By utilizing private packets, respective encoding devices transmit encoding difficulties serving as the data for statistical multiplexing to a multiplexer () via the same transmission channels as encoded video data and audio data are transmitted. The multiplexer () conducts multiplexing processing on data supplied from the respective encoding devices at a first rate R1 larger than a transmission rate on a transmission channel of a subsequent stage, and outputs a transport stream (TS) including the private packets to a statistical multiplexing computer. In addition, the multiplexer () conducts multiplexing processing on data obtained by removing the private packets, at a second rate Rwhich is equal to the transmission rate on the transmission channel of the subsequent stage, and outputs a transport stream (TS) which does not include the private packets to the transmission channel of the subsequent stage.

A method for processing a moving picture in which input digital moving picture signals of a pre-set picture rate are processed in accordance with pre-set picture processing and the processed digital picture signal are transmitted. The input digital moving picture signal has plural field pictures. The processing method includes a first step of detecting a redundant field from the input digital moving picture signals, a second step of eliminating the detected redundant field from the plural field pictures, a third step of deciding, from a string of field pictures from which the redundant fields have been eliminated, the combination of a top field and a bottom field constituting a frame to be processed in accordance with the pre-set picture processing, and outputting the results of decision, a fourth step of inserting a pre-set signal in the field picture string from which the redundant field has been eliminated for generating picture signals for processing having the same picture rate as the rate of the input digital picture signal, and a fifth step of processing the picture signals for processing in accordance with the pre-set picture processing based upon the results of decision.

Processing of redundant fields in a moving picture to achieve synchronized system operation

A repeat use data inserting apparatus for repeatedly inserting repeat use data into program data in accordance with appropriate timings. The apparatus comprises a data holding unit and a data multiplexing unit. The data holding unit holds the repeat use data made of a plurality of material data in the form of separately encoded streams. The data multiplexing unit multiplexes separately encoded streams of a plurality of material data constituting the program data during a period other than a data insertion period during which the repeat use data is inserted into the program data. The data multiplexing unit further inserts repeatedly the repeat use data into the program data during the data insertion period by multiplexing the separately encoded streams of the plurality of material data constituting the repeat use data held in the data holding unit.

Repeat use data inserting apparatus and digital broadcast transmitting system

A data multiplexer and a method thereof for multiplexing audio data, video data and additional data for digital television broadcasting. Size information for such data may be obtained and supplied by way of a CPU bus to a CPU which utilizes such size information in controlling a multiplexing operation. The audio, video and additional data may be multiplexed under the control of the CPU without being supplied to the CPU. As a result, high speed multiplexing may be performed.

Data multiplexing apparatus and method thereof

Processing of redundant fields in a moving picture to achieve

A magnetic reproducing apparatus is provided with an improved secondary beat signal cancel circuit for reducing a secondary beat signal of a low-frequency converted chroma signal leaked into a reproduced luminance signal without deteriorating vertical resolution at the edge of an oblique check signal. The secondary beat signal cancel operation is interrupted during a period in which no vertical correlation exists between the edge portions of two succeeding horizontal lines of the oblique check signal.
