The method and apparatus operates in a VCR to identify selected broadcast segments, such as commercial advertisements, of a television signal in real-time for the purpose of suspending recording of the television signal during each unwanted segment. A signature pattern associated with each segment of the television signal is detected and compared to stored signature patterns representative of selected segments such as commercial advertisement segments. If the signature pattern matches one of the stored signature patterns, the segment is thereby immediately identified as being one of the selected segments and is processed in real-time to suspend recording during the segment. If the signature pattern of the segment does not match any of the stored signature patterns, the segment is analyzed to determine whether the segment is nevertheless a selected segment and, if so, its signature pattern is stored along with the stored signature patterns. The analysis to determine whether the segment is nevertheless a selected segment is performed by detecting the length of the segment upon its completion and then determining whether the length of the segment matches one of a pre-determined set of permissible selected segment lengths such as standard commercial advertisement segment lengths of 15 seconds, 30 seconds, or 60 seconds. If so, the segment is identified as being a selected segment and its signature pattern is stored along with the other stored signature patterns such that, the next time the same segment is encountered, its signature will then match the stored signature and therefore the segment can be immediately identified and recording of the segment can be immediately suspended.

An automatic adaptive dimensioning program for CAD software in which dimension annotations are created by the CAD program automatically as an object is drawn and automatically associated with the object. Thereafter, changing the length of the object automatically changes the associated dimension annotation, or alternatively, changing the associated dimension annotation automatically changes the length of the object. When another object is interposed into or superposed onto an intermediate position of the existing object, the automatic adaptive dimensioning annotation feature of the invention automatically creates dimension annotations corresponding to the position of the new object relative to the existing object. The new object can be automatically positioned in relation to the existing object by specifying interposition dimensions or segment lengths in the dimension annotations.

Delivery of short audio communications to remote end user devices uses discrete message-oriented service messages for delivery of the audio messages. Audio information is captured, encoded by means of audio compression technology, and stored at a message center. Alternatively, the audio information may be stored in an uncompressed format and compressed immediately before delivery. The compressed audio information is transmitted by means of Short Message Service or another discrete message-oriented service to the end user device, where it is decompressed and played to the recipient. Message delivery can be accomplished in parallel with some other ongoing activity at the end user device. The major fields in a Short Message Service message used to carry encoded audio information are a Type of Data field, including information on the type of translator needed to decompress the message field, a Short Message Identifier, a Length field, and the coded audio information. If the audio information is too large to be contained in a single Short Message, segmentation and reassembly techniques commonly known in the art are applied to break the information into segments, each of which is placed into a separate Short Message having the fields: Type of Data; Short Message Identifier; Total Segments; Number of Enclosed Segment; Segment Length; and Coded Audio Information Segment. At the end user device, the Short Message can be stored until the end user listens to the audio information. The intervening network can be a radio link, the Internet, or some other network. The invention may also be utilized by a mobile user to send short audio messages to a message center and / or a second end user device.
