Problems solved by technology

Because in the case of large traffic, the traffic per second can reach hundreds of thousands of pps, and the peak value can reach hundreds of thousands or millions of pps data packets, and every time a packet comes, an interruption is generated, and the on-site processing and switching of each interruption The context consumes at least three CPU cycles on average, which is imaginable for a packet capture platform

Embodiment Construction

[0023] The specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] Such as 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 and a network card interface for receiving or sending data from the network and the like. The application program module provides TV end user sof...

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. ...
