Abstract
Description
Technical Field
[0001] This utility model relates to the field of set-top boxes, and in particular to a voice-controlled mobile IPTV set-top box. Background Technology
[0002] Currently, IPTV set-top boxes on the market primarily connect to a wired network via an RJ45 port or connect to a router's Wi-Fi hotspot via a Wi-Fi module for video playback. This requires a wired network connection to the user's indoor location, limiting its usability. It cannot be used in areas without wired network access, such as outdoors or temporary residences, failing to meet user needs in diverse scenarios and thus restricting its application. Furthermore, existing IPTV set-top boxes lack voice control functionality, requiring users to manually input commands or operate via remote control, resulting in an inconvenient user experience, especially when navigating complex menus and querying information, leading to low efficiency.
[0003] Figure 1 This is a schematic diagram of a common IPTV set-top box in existing technology. It uses the MTK MT8691 control chip (U1: MT8691), is equipped with eMMC FLASH and DDR4 DRAM, and is connected to DC 5V via a MIRCO USB interface, the same as that of a regular mobile phone. The entire unit is powered by a multi-output power management chip (U2: M2156K). Audio and video are output via an HDMI interface. The set-top box is equipped with a 2T2R 2.4G / 5G dual-band Wi-Fi module (U5: MT7668), which allows for internet access and audio / video playback via Wi-Fi hotspot. It also has an RJ45 network port input terminal, allowing for wired internet access and audio / video playback. However, while the above IPTV set-top box commonly uses Wi-Fi hotspots or RJ45 wired connections for internet access and playback, both require a wired network connection; it cannot be used in areas without a wired network connection. Furthermore, this IPTV set-top box lacks voice control, resulting in a less convenient user experience. Utility Model Content
