Abstract

The embodiment of the invention relates to the technical field of digital television (TV), and provides a method, a device and a system for allocating IPQAM (internet protocol quadrature amplitude modulation) resource, and can quickly determine frequency point resource matched with the needed bandwidth and improve the on-demand concurrency capability of the system. The method comprises the following steps: obtaining any one of first elements in a frequency point chain table stored with array elements in an available bandwidth array according to region identification (ID) and the needed bandwidth for the on-demand IPQAM resource; according to the first elements, determining the array elements in a first global array corresponding to the first elements, and removing the first elements; and according to the array elements in the first global array, determining any one available port and pmt (Program Map Table) pid in the array elements, and deleting the determined available port and pmt pid. The embodiment of the invention is mainly applied to management of the IPQAM resource.

Description

technical field [0001] The present invention relates to the technical field of digital television, in particular to an IPQAM resource allocation method, device and system. Background technique [0002] In the HFC (Hybrid Fiber Coax, fiber-coaxial cable hybrid) video-on-demand system, the set-top box sends a video playback request to the streaming media server, and the streaming media server sends an IPQAM (Internet Protocol Quadrature Amplitude Modulation, Internet Protocol Quadrature Amplitude Modulation) resource The manager applies for IPQAM resources, obtains an available IPQAM resource, and the streaming media server sends the code stream to the obtained IPQAM resource, and at the same time replies with the IPQAM resource information corresponding to the set-top box, and then the set-top box can solve the IPQAM resource information according to the IPQAM resource information returned by the streaming media server. Call out the corresponding code stream. [0003] Becaus...
