Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. The values ​​of the following components are only preferred embodiments, and do not constitute limitations on the scope of protection of the present invention.

[0018] see figure 1 , a set-top box network port performance testing method, comprising the following steps:

[0019] S1. Production of special network RJ45 crystal head: In 10 / 100M network communication, the RJ45 interface line defines 8 lines, of which only 4 lines are useful (from left to right the contact points are 1, 2, 3, 6), nothing else works. Points 1 and 2 are respectively: TX+ and TX- are used to send data, points 3 and 6 are respectively RX+ and RX- are used to receive data. The function of the special network RJ45 crystal head is to realize the spontaneous collection of network data. The TX, RX receivin...

Abstract

The invention discloses a method for testing the performance of a network port of a set-top box. The method comprises the following steps: (1) preparing a special network RJ45 registered jack; (2) inserting the special network RJ45 registered jack in the network port of the to-be-tested set-top box; (3) running a set-top box network port performance detection thread by the to-be-tested set-top box; (4) transmitting a network data packet back to the network port of the set-top box after passing through the registered jack, and receiving and processing the network data packet through a receiving module of the thread; (5) if the particular network data packet is not successfully received, adding 1 to a packet loss counter; (6) if the particular network data packet is received, but the data CRC in the data packet fails the verification, adding 1 to a wrong packet counter; and (7) if the particular network data packet is received, and the data CRC in the data packet passes the verification, adding 1 to a successfully received data packet counter. By adoption of the method disclosed by the invention, the link and connection correctness of the physical network port of the set-top box can be tested, the packet loss rate and the throughput of the network port of the set-top box can also be tested, and long-time pressure burn test is facilitated.

Description

technical field [0001] The invention relates to the technical field of set-top boxes, in particular to a method for testing the performance of a network port of a set-top box. Background technique [0002] A digital video conversion box (English: Set Top Box, referred to as STB), commonly known as a set-top box or a set-top box, is a device that connects a TV to an external signal source. It can convert the compressed digital signal into TV content and display it on the TV. Signals can come from cable, satellite dishes, broadband networks, and terrestrial broadcasts. The content received by the set-top box is to receive digital content, including electronic program guide, Internet web pages, subtitles, etc., in addition to the images and sounds that can be provided by analog TV. It enables users to watch digital TV programs on existing TV sets, and conduct interactive digital entertainment, education and commercial activities through the network. [0003] With the develop...
