Abstract
For the acquisition of multistandard video data a decoder is used with a register 201 having 24 cells for storing 3 times 8 bit of data. Each of the three bytes are connected with logical devices in order to compare the content of the cells with given start codes. Start of the register 202 is byte3, followed by byte2 and byte 1. In addition a second 8 bit register 202 is connected in parallel to the register 201. The content of byte3 is also fed to a Hamming (8/4) decoder 203 and of byte2 to a Hamming (8/4) decoder 204. Each decoder output of 4 bits is fed to the assigned 4 bits of the register 202, respectively.

Method for acquisition of multistandard video data comprising the steps of:
- loading an incoming data stream is loaded into a first memory;
- performing a parallel search for different start codes on the data stream containing for different services different framing code, when service in an actual video line is not specified;
- and
- looking for start codes which are changeable by configuration.
