Video service, the focus of users' attention, has become an indispensable way of life for people to obtain information, leisure and entertainment. Both long and short videos are in a stage of rapid development. As 5G network develops, its high reliability, high bandwidth, and low latency features will promote the rapid development and continuous innovation of video terminals in terms of shape, control mode and service mode, and deliver a brand-new experience to users.
New Video Terminals Bring High-Quality Experience
4K video can meet the high-quality requirements of home users for video definition, but there is still room for improvement in sound quality. Due to the limitations of equipment configuration, the combination of a common video terminal and a conventional TV set is difficult to offer high-quality sound effects like Dolby 5.1 surround sound. However, the cost of configuring external devices such as power amplifiers and high-quality speakers is relatively high.
To meet the above needs, ZTE has developed SoundBar terminals that integrate media players and high-quality audio devices. The SoundBar terminals can play UHD videos with high-quality sound effects, allowing users to enjoy a superior viewing experience at a reasonable price.
New Technologies Bring Changes to Terminal Control
The far-field natural voice interaction technology at a distance of three to five meters enables the control of terminals through natural voice interaction. This technology has matured, and has been gradually applied on terminals.
The process of converting natural voice into device control commands requires the cooperation between the local terminal and the remote system. The local terminal collects voice information and uploads it to the remote voice processing system for speech semantic analysis and control command conversion. After the completion of the processing, the remote system feeds back to the terminal. The whole process requires at least two network interactions. The reliability and timeliness of an access network are the basic guarantee for a better voice interaction experience. Mobile 5G networks featuring high bandwidth, high reliability and low latency can provide reliable service guarantee for real-time voice interaction and meet the growing demand for voice services.
Integrating AI and IoT technologies will make man-machine interaction more intelligent and easy to operate. The new control mode will be extended to all smart home devices.
5G + AI + far-field voice: The far-field voice technology allows users to use their voice for operations such as content searching, video control, information input and device configuration, which completely changes the terminal control mode by offering a true hands-free user experience. The integration of 5G MEC and AI enables intelligent voice interaction. Multimedia terminals can be upgraded to smart terminals providing new services that involve accompanying the elderly and educating children.
5G + IoT + far-field voice: By integrating IoT and far-field voice technologies, video terminals can control smart home devices through natural voice interaction. The traditional complex button and panel control can be simplified to voice commands for device control, and thus video terminals evolve into the control center of smart home.
ZTE has launched a series of smart voice terminals that integrate far-field voice, AI, and IoT technologies. With these smart voice terminals and the video system, ZTE is actively developing scenario-oriented and intelligent far-field voice control services, thus evolving video services towards intelligent voice control (Fig. 1). This allows users to enjoy a brand-new viewing experience and helps operators enhance customer stickiness while expanding new service opportunities.
