Problems solved by technology

But until now, all other P2P solutions and products are computer-based solutions, and P2P solutions based on relatively simple and cheap IPTV set-top boxes have not been able to implement due to the relative technical difficulty of their implementation on limited resources. solve

Embodiment Construction

[0071] figure 1 It is the overall structure diagram of the player. The player includes five separate POSIX threads (ie pthreads): main thread (the main thread will eventually become the control thread), video thread, display thread, audio thread and voice thread. These latter four threads were spawned by the main thread before it became the thread of control. The player can play individual audio or video files, or audio and video files, but cannot play two files of the same type at the same time.

[0072] figure 2 It is the process of the main thread. First, we use the display device driver function (FBIO_GETSTD_ioctl()) to detect the video standard (PAL or NTSC) used, and then establish the thread environment variables while parsing the command line parameters. Initializes the compiler / decoder and its event trace module (TraceUtil) for trace logging. Open the Pause object and the Rendezvous object to synchronize the created threads. When one or more threads are created, ...

Abstract

The invention provides a controlling method used for a player of a peer-to-peer computing set top box, which is used for a player of a P2P (Peer-to-Peer) set top box to play a media file which is not completely downloaded in the P2P set top box, thereby solving the problem of downloading, playing while sharing of the P2P set top box. The realizing method of the player comprises: step 1) analyzing requirement; step 2) designing a module according to the analysis file of the step 1); step 3) designing and realizing a main thread and a control thread of the player according to the file of the step 2); step 4) designing and realizing decoding and playing of an audio file and a video file according to the file of the step 2); step 5) designing and realizing a file loading and sharing module according to the file of the step 2); and step 6) providing functions, namely play, pause, stop, position, fast forward and quick backward, for the player so as to ensure that the player can be automatically positioned to corresponding time to start playing after a user fills the time and presses the enter key.

Description

technical field [0001] The present invention is a player for P2P (Peer-to-Peer) set-top boxes, which plays the media files that have not been completely downloaded in the P2P set-top boxes, and solves the problem that the P2P set-top boxes download and play while sharing, thereby realizing It has created a phenomenon that many people watch a good resource online, perfected the function of the P2P set-top box, and belongs to the field of peer-to-peer network applications. Background technique [0002] The P2P network model breaks the traditional C / S model communication method. Under the previous C / S model, the communication between the client and the server is based on the rules set by the server. The P2P model allows users to set their own rules and build their own network environment. In order to cooperate with the Internet, the P2P model provides an approximate plug-and-play feature, that is, you can use the P2P features as long as you connect to the Internet. Another adv...
