Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] Such as figure 1 Shown is a schematic flow chart of an on-demand method for optimizing bandwidth allocation provided by an embodiment of the present invention. It should be noted that this embodiment is described from the side of the terminal that needs to perform on-demand. The method includes the following steps:

[0030] S101: Join the LAN multicast group through the transmission control terminal when the player is started.

Abstract

The invention provides an optimal bandwidth distribution demand method and device. The method comprises the following steps: when a displayer is started, a local network multicast set is added through a transmission control terminal; the local network multicast set is utilized to inquire whether resource nodes in the local network contain audio and video documents needing to be demanded or not; and the internal network connection with the resource nodes provided with the audio and video documents in the local network is preferentially established to carry out the demand. According to the invention, when a user demands, the multicasting technology can be used for downloading audio and video documents preferentially from the resource nodes of the local network; and because the data transmission rate in the local network is greatly higher than the rate of the external network, the demand speed of the user is increased, and the occupation of the bandwidth of the routing exit is further decreased.

Description

technical field [0001] The invention relates to the technical field of multimedia playing, in particular to an on-demand method and device for optimizing bandwidth allocation. Background technique [0002] In the existing player, when the playback terminal plays the audio and video files, it directly obtains the audio and video file resources from the external network through the router. Although there is a data transmission speed of 100M / S inside the LAN, the bandwidth between the LAN and the external network is still relatively small. At present, the most common one is the asymmetric digital subscriber line (Asymmetric Digital Subscriber Line, ADSL) with a bandwidth of 2M in the LAN. It is connected to an external network, such as the Internet. [0003] In this way, the online playback technology of existing players has the following defects: when multiple users in the local area network access the external network at the same time to perform audio and video on demand, du...
