Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for transmitting a stream of digital multimedia data on a distribution communications network. SOLUTION: A server is provided for segmenting a stream into data blocks on first and second boundaries. The first boundary indicates the number of sets of transport system packets, and the second boundary denotes the transport system packet including a time stamp. A scheduler schedules the blocks segmented for transmission. The server decodes the segmented blocks, finds out the time stamp and makes the transmission of data blocks coincident with the time value of the time stamp. The number of sets of transport system packets can be determined at the time of connection setting and does not become a prescribed value concerning all sessions.

Abstract: Method and apparatus are provided for transmitting a stream of multimedia digital data over a distribution communications network. A multimedia stream server segments the multimedia digital data stream into data blocks on a first boundary and a second boundary. The first boundary is a set number of transport system data packets and the second boundary is a transport system data packet including a timestamp. A scheduler schedules the segmented data blocks for transmission. The multimedia stream server decodes the segmented data blocks to locate the timestamps and matches the transmission of the located timestamp data block with a time value indicated by the timestamp. The set number of transport system data packets can be determined at connection setup and is not a predetermined value for all sessions. At the receiver, batch processing of received multimedia data can be provided.

Abstract: LEGIBILITY ENHANCEMENT FOR ALPHANUMERIC DISPLAYS Alphanumeric CRT display has normal/reverse video attribute. In reverse video, the character dots are made wider than in normal video, to equalize the apparent width of the dots in the two modes.
