Abstract
Description
Technical Field
[0001] This utility model relates to a high-definition interactive converged set-top box, and more particularly to a device that integrates a PON (Passive Optical Network) device and a DVB (Digital Video Broadcasting) set-top box into one unit. Background Technology
[0002] With the widespread adoption of high-definition televisions, many homes, hotels, and public places have installed them. The traditional method for high-definition television signal transmission and control uses a separate external ONU (Optical Network Unit) + DVB (Digital Video Broadcasting) set-top box. The ONU device is located on the user's side, connected to the user's computer, mobile phone, or other smart terminal via twisted-pair cable or Wi-Fi; the DVB set-top box is responsible for decoding the signal and transmitting it to the television for playback. However, this separate setup has several drawbacks: the connection between the DVB set-top box and the ONU device requires cables or additional external connection devices, which takes up considerable space and can be inconvenient for users during installation. After the remote control commands are parsed by the DVB set-top box, it connects to the network and exchanges data through the ONU device in the PON (Passive Optical Network) fiber optic system to obtain television data; the entire process is quite cumbersome.

The device achieves communication between the PON module and the DVB module through the internal PHY layer, without the need for external connection cables.
[0032] In this embodiment, see Figure 5 The PON module and DVB module are connected through an internal PHY communication circuit, which includes a network transformer matching unit, a capacitor matching unit, and a signal matching unit.

[0036] In this embodiment, the first memory includes FLASH memory, and the second memory includes DDR3 memory and FLASH storage.
[0037] Traditionally, high-definition televisions require an external DVB set-top box to connect to the internet, while the ONU device connects to user computers, mobile phones, and other smart terminals via twisted-pair cables or Wi-Fi. This configuration not only occupies space but can also cause inconvenience to users during installation. This new high-definition interactive converged set-top box integrates the PON module and DVB module into a single device, connected together via a PHY connection circuit (internal PHY layer), improving operating speed, enhancing user experience, and significantly reducing user costs. Simultaneously, users can control the television controlled by the DVB set-top box via network-connected smart devices, including streaming 4K high-definition video services, eliminating the need for a separate television connection.
