Network TV set and method for capturing datagram thereof

Abstract

The invention discloses a network TV set and a method for capturing a datagram thereof. A network module of the network TV set comprises a direct memory storage controller (a DMA controller) which is connected with a network adapter driving module and a network card interface respectively; and the network TV set is provided with a bumping block which is connected with the network card interface through the direct memory storage controller (the DMA controller). The TV set and the method ensure that a network adapter driver and a user program can directly access and operate a common memory spaceby building a common memory space of a network card and a user area on the network TV set so as to reduce memory copy of a system kernel to a user space, reduce the spending of calling a system synchronously, and improve the playing fluency of video frequency and audio frequency data of the network TV set.

Description

technical field

[0001] The invention relates to the technical field of network television, in particular to a network television and a datagram capturing method thereof. Background technique

[0002] The structure of the currently commonly used network TV is as follows: figure 1 As shown, the network TV includes: a TV body, a multimedia processing module, a control module connected between the TV body and the multimedia processing module, a video module and an audio module, and a network module and an application module connected to the multimedia processing module. The multimedia processing module mainly processes audio and video signals, which includes a hardware chip and underlying system software, while the underlying system software includes two parts, an operating system kernel and a driver (including a network adapter driver), and the hardware chip includes a CPU and a memory space . The network module includes a network protocol stack, a network adapter and so on. ...
