The widespread adoption of Wi-Fi in new classes of smaller devices made the need for ad hoc networking much more important. Even without a central Wi-Fi hub or router, it would be useful for a laptop computer to be able to wirelessly connect to a local printer. Although the ad hoc mode was created to address this sort of need, the lack of ...
Wireless HDMI is the wireless transmission of high-definition audio and video signals between devices, using unlicensed radio frequencies like 5 GHz, 60 GHz, or 190 GHz. This technology eliminates the need for an HDMI cable , allowing users to transmit signals wirelessly between the component device and the display device.
CEC [3] is a separate electrical signal from the other HDMI signals. This allows a device to disable its high-speed HDMI circuitry in sleep mode, but be woken up by CEC. It is a single shared bus, which is directly connected between all HDMI ports on a device, so it can flow through a device which is completely powered off (not just asleep).
The HDMI specification is not an open standard; manufacturers need to be licensed by HDMI LA in order to implement HDMI in any product or component. Companies that are licensed by HDMI LA are known as HDMI Adopters. [91] DVI is the only interface that does not require a license for interfacing HDMI. [citation needed]
A wireless ad hoc network does not have fixed topology, and its connectivity among nodes is totally dependent on the behavior of the devices, their mobility patterns, distance with each other, etc. Hence, wireless mesh networks are a particular type of wireless ad hoc networks, with special emphasis on the resultant network topology.
The network controller implements the electronic circuitry required to communicate using a specific physical layer and data link layer standard such as Ethernet or Wi-Fi. [a] This provides a base for a full network protocol stack, allowing communication among computers on the same local area network (LAN) and large-scale network communications through routable protocols, such as Internet ...
2023 saw the release of wireless TVs which connect to other devices solely through a transmitter box with an antenna that transmits information wirelessly to the TV. [48] Demos of transparent TVs have also been made. [49] There are TVs that are offered to users for free, but are paid for by showing ads to users and collecting user data. [50]
It could be used for streaming a recorded video from a PC media center to a portable player, or a live video from a digital video camera to a TV. Support for the H.263 baseline is mandatory. The MPEG-4 Visual Simple Profile, and H.263 profiles 3 and 8 are optionally supported, and covered in the specification.1
