The checksum shall be calculated by treating the DSMCC_section as a sequence of 32-bit integers and performing on
28、es complement addition over all the integers, most significant byte first, then taking the ones complement of the result. For the purpose of computing the checksum, the value of the checksum field shall be considered 0. If the message length is not a multiple of four bytes, the message shall be cons

If the computed result is 0, then the result shall be set to 0xFFFFFFFF (the alternative value for a ones complement representation of 0). In cases where a checksum is not desired, the value of this field shall be
30、set to 0 to indicate the checksum has not been calculated. This feature is useful for networks where error detection is provided at a protocol layer lower than the MPEG-2 Transport Stream.

45、 for DSM-CC Technologies de Iinforma tion - Codage g a suite of uniform interfaces are visible to the application, shielding it from the details of inter-working among heterogeneous networks - e.g., Hybrid Fiber Coax (HFC), Asynchronous Transfer Mode (ATM), Asymmetric Digital Subscriber Loop (ADSL),
46、 Internet Protocol (IP), and combinations of these technologies as part of an end-to-end multimedia system. In other words, a server may simultaneously and uniformly interact through a single network interface with clients connected to different network types, without requiring a separate network in
47、terface to each client. The session signaling layer provides a uniform, flexible, and extensible method for managing heterogeneous resource types. In addition to the network and service types described in this specification, DSM-CC may be extended to support other networks and services through the d
48、efinition of new resource types. In DSM-CC, a bit stream is sourced by a Server and delivered to a Client. Both the Client and the Server are logical embodiments and do not imply a singular device in an actual implementation. Application/service examples are interactive multimedia retrieval (includi
49、ng video-on-demand), Internet access, digital video broadcasting, data downloading, and audio/video/graphics conferencing. 0.1 Guiding Factors in the Formulation of DSM-CC The DSM-CC specification was influenced by the following factors: 0 A wide range of network topologies may be used to deliver DSM-CC. 0 Resources are finite and need to be managed. 0 Latencies need to be minimized to provide (interactive) services. 0 DSM-
