Abstract
Abstract An apparatus and method for effectuating local reception and processing of source program signals representative of a compressed digital multimedia program received from a remote multimedia server are disclosed. The multimedia server transmits a selected multimedia program as a custom ordered series of discrete program segments to a local set-top control system, which buffers and decompresses the compressed program segments for presentation on a local display monitor. A local set-top control system preferably includes a direct access storage device adapted to buffer a predetermined number of compressed program segments received from a multimedia server, some of which may be non-sequentially ordered and others of which may be sequentially ordered. A novel formatting methodology provides for the sequential presentation of the program segments asynchronously distributed on one or more data storage disks disposed in the direct access storage device. A user-definable presentation control window for performing local VCR-type presentation control functions for the portion of a multimedia program buffered in the direct access storage device is also provided through the novel formatting methodology. The novel formatting methodology also provides concurrent presentation and buffering of program segments received from the multimedia server for on-demand viewing of a selected multimedia program.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
144 words
A multimedia control system, coupled to a display and a communication channel, for communicating with a remote multimedia server having means for transmitting source program segments representative of a multimedia program as a custom ordered series of the source program segments over the communication channel, the multimedia control system comprising: an input buffer for buffering the source program segments received from the communication channel; a direct access storage device, coupled to the input buffer, including at least one data storage disk; and a controller for coordinating writing of the source program segments buffered in the input buffer to the data storage disk, and for coordinating reading of the source program segments from the data storage disk as sequentially ordered local program segments; whereby the sequentially ordered local program segments read from the data storage disk are transmitted to the display for sequential presentation thereon.
Claim 2
Dependent Claim
69 words
A system as claimed in Claim 1, wherein: the custom ordered series of the source program segments include non-sequentially and sequentially ordered source program segments; and the controller coordinates writing of the non-sequentially ordered source program segments received from the communication channel to the data storage disk, and coordinates reading of the non-sequentially ordered source program segments from the data storage disk as the sequentially ordered local program segments.
Claim 3
Dependent Claim
71 words
A system as claimed in Claim 1, wherein the multimedia server transmits the source program segments to the communication channel arranged in packets, wherein each of the packets comprises no greater than a predetermined maximum number of the source program segments; and the input buffer comprises memory for buffering at least the predetermined maximum number of the source program segments arranged in each of the packets received from the communication channel.
Claim 4
Dependent Claim
54 words
A system as claimed in Claim 1, wherein: the multimedia server further comprises coding means for coding the source program segments defining the multimedia program as compressed source program segments; and the multimedia control system further comprises a decoder for decoding the compressed sequentially ordered local program segments read from the data storage disk.
Claim 5
Dependent Claim
58 words
A system as claimed in Claim 1, wherein the multimedia control system further comprises an output buffer coupled to the direct access storage device and the input buffer, and the controller coordinates transferring of at least some of the source program segments received from the communication channel concurrently to the direct access storage device and the output buffer.
