Abstract: PROBLEM TO BE SOLVED: To distribute audio and video through the Internet by deciding a video or audio format and a bit rate which are suitable for each client and customizing the bit rate of video or audio in a detailed manner. SOLUTION: When a client connects its equipment an Internet convolution audio/video server (ICAVS), the state of a network between the client and the server and the capability of a client system are decided as the occasion demands and they are stored in a client information database 14. For instance, when the client requests audio or video contents, an audio/video data manager 6 searches the contents in an audio/video file server complex 7. Next, a streaming traffic pacer 9 makes audio or video a stream for the client.

Abstract: An Integrated Single Frame Buffer Memory For Storing Graphics and Video Data The present invention provides an integrated display system for multi.-media workstations wherein graphics image and video data are merged in a single frame buffer. The integrated display system employs 3-port VRAMs with a first serial access port for display data output, and a random access port for graphics data, a second serial access for video data input. The display system includes a single frame buffer memory system for a multi-media workstation which operates compatibly with display systems and logic designed for dual frame buffer systems and it uses the 3-port VRAM in combination with a means incorporating improved input locking, video update or refresh, and encoded video data input stream.
