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

It is made possible to record, on a recording medium on which original image data before compression is recorded, data resulting from a first coding processing performed when coding the data by a variable rate compression and coding system and to code quickly in real time when performing a second coding processing from that recording medium. Video data is reproduced by a VTR from a master video tape on which source video data is recorded and the first coding processing is carried out at a compressing and coding apparatus The bit rate, allocation data, etc. obtained by this coding processing are stored in a predetermined region of the master video tape via the VTR When the master video tape is used, the second coding processing can be quickly carried out without reading the bit rate data etc. from another apparatus.

Wireless communication device having a reconfigurable matching circuit

A synchronous control device having a memory 101 for storing block data blocked in terms of a pre-set data amount, a clock generating circuit 102 for generating input side clocks which are based on a data rate to be synchronized, and a memory control unit 103 for generating output side clocks C.sub.out responsive to input side clocks C.sub.in from the clock generating circuit 102. The memory 101 stores the block data on the block basis, based on the input side clocks C.sub.in from the clock generating circuit 103, and outputs the stored block data based on the output side clocks C.sub.out from the memory control circuit 103. The memory control circuit 103 detects a difference between the input data volume and the output side data volume in the memory 101 for varying the speed of the output side clocks responsive to the amount of the detected difference so that the output side clocks will be synchronized with the input side clocks C.sub.in from the clock generating circuit 103.

Synchronous control apparatus

An image data processing method in a signal processing method for coding a picture sequence comprised of I-pictures, P-pictures, and B-pictures accommodated in GOP's, wherein when the pictures of a certain GOP among a series of GOP's are changed, the coding is performed replacing the first picture of the sequence of the changed pictures of the GOP with an I-picture of a picture number prescribed in accordance with the position of change so that coding is possible without existence of a picture in the preceding GOP.
