Abstract: To distinguish whether changes occur in an image sequence or not, a change criterion is necessary. In the invention, this change criterion is derived from the frame differences, the frequency distribution of which is evaluated. This frequency distribution is formed over at least two images. For each frequency distribution, the maximum in the range of small frame differences and the turning points nearest to the maximum are determined. From this maximum and lower turning point, a decider threshold value is determined which is averaged with the decider threshold values of the other frequency distributions to form the change criterion. These measures provide a change criterion adapted to interference, for example the camera noise.

Abstract: A task queue is structured as a single-keyed indexed file in which the key has a most significant portion indicating a priority level and a less significant portion that is ordered with the loading of the tasks into the queue. For any given task record in the queue, the less significant portion of the key is determinable from a respective task identifier. Preferably the less significant portion of the key is a "time stamp" including the current date when the task was created and a representation of the data processor's internal 24 hour time clock, and a task identification number is formed by appending a node number to the time stamp in the event that the system has multiple processors capable of creating different tasks at the same time. This format of the single key causes an internal ordering of the records in the queue that is sequential with respect to the less significant portion of the key within blocks of records having the same priority. Therefore, due to the relationship between the key and the task identification number for each task record in the queue, it is possible to quickly search for the record having a requested task identification number. Conventional memory management facilities for accessing key-indexed files can be used for searching the queue. In this case the queue is searched by random or "key next" access to repeatedly step through the possible priority levels until a record having a matching key is found or the end of file is reached. When a record having a matching key is found, the requested task identification number is compared to the identification field of the record. If there is a match,   the desired record has been found. If not, then searching continues by sequential access until there is a match of the identification numbers or until the keys no longer match.

Abstract: The invention relates to a process for transmission of information relating to moving pictures and is particularly intended for pictures with moderate movement. The invention makes possible transmission on telephone lines with a transmission rate of under 64 kbit/sec. by dividing each picture into macro picture elements comprising a number of image points from the luminance block and the two chrominance blocks, which image points correspond to the same physical picture area. A movement vector is formed if possible and is transmitted for each macro picture element. The picture is scanned in rows or in columns and the movement vectors for macro picture elements, which adjoin the current macro picture element and which have been scanned before it, are mutually compared in order to check whether they satisfy certain conditions, and are compared with the movement vector in the current macro picture element in order to check whether the said vector is identical with any of the the movement vectors in the adjoining macro picture elements or whether the movement vector in the current macro picture element is identical with another movement vector or whether no movement vector exists in the current macro picture element. These operations are coded and transmitted by means of variable length-­coding, preferably arithmetical coding, which coding is dependent upon which condition of the movement vectors in the adjoining macro picture elements is satisfied.
