Abstract: A method and apparatus for storing a variable length operand offset in a computer instruction is provided. An operand base is stored in a computer instruction. Also stored in the computer instruction is a variable length operand offset that is associated with the operand base. In addition, an operand offset length is stored within the computer instruction that defines the length of the variable length operand offset. Storing an operand offset length with each variable length operand offset in a computer instruction provides for the reduction of unused space.

Abstract: A method and system are provided for delivering video from a client to a server over a communication medium with a limited bandwidth. An initial image quality that allows the video to be displayed in real time at the client is determined based on a predetermined frame rate and the limited bandwidth. Video having the initial image quality is transmitted to the client. While transmitting the video to the client, the server receives a message from the client that indicates selection of a second frame rate that is slower than the predetermined frame rate. In response to the message from the client, the server determines a second image quality that allows the video to be displayed in real time at the client based on the second frame rate and the limited bandwidth. The second image quality is higher than the initial image quality. The video with the second image quality is then transmitted to the client. A “snapshot” feature is also provided. A predetermined user input is received at the client.
