Embodiment Construction

[0021] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0022] The controller chips of existing cable TV set-top boxes are all provided with standard serial peripheral bus interfaces, which are a kind of synchronous serial peripheral )) communicate with various peripheral devices (such as the Ethernet communication device 20 mentioned below) in a serial manner. The embodiment of the present invention utilizes the serial peripheral bus interface to realize communication with the Ethernet.

[0023] Ethernet (Ethernet) is a computer local area network networking technology based on the IEEE802.3 standard formulated by the IEEE, which specifies the content of the physical layer connection, electrical signals, and media ...

Abstract

The invention discloses a cable television set top box, system and method for communication with an Ethernet. The method for communication with the Ethernet includes the following steps: the cable television set top box sends a query frame to an Ethernet communication device via a serial peripheral bus interface; the cable television set top box receives a response frame, which is sent by the Ethernet communication device based on the query frame, via the serial peripheral bus interface; the cable television set top box sends a data frame reading command to the Ethernet communication device based on the response frame via the serial peripheral bus interface; and the cable television set top box receives an Ethernet data frame which is from the Ethernet and sent by the Ethernet communication device based on the data frame reading command via the serial peripheral bus interface. Through use of the set top box, the system and the method, a cable television unidirectional set top box is capable of realizing an internet surfing function without being transformed and thus the financial pressure of operators is reduced effectively.

Description

technical field [0001] The invention relates to the communication field, in particular to a cable TV set-top box communicating with an Ethernet, a system and a method. Background technique [0002] With the continuous development of global information technology, the integration of triple play has changed from the theoretical stage to the substantive development stage. With the continuous intensification of market competition and the basic completion of the digitalization of domestic cable TV networks, cable TV users have higher and higher service requirements. To the network to the development of multiple two-way network. [0003] Because cable TV users have a very strong demand for cable digital TV set-top boxes to access the Internet, the cable TV digital set-top boxes are required to support the Ethernet function. However, for example, in rural areas where the geographical location is relatively remote and cable TV users are relatively scattered, it is difficult to tra...
