Abstract

The invention discloses a business video telephone set with a hidden camera. The business video telephone set is characterized by comprising a handle, a liquid crystal screen component, a light guide pillar, a telephone set front cover, a loudspeaker, a microphone component, a key component, a base, a telephone set bottom cover and a master control circuit board component. The business video telephone set has the advantages that: buckles of a metal sliding way are tightly buckled with a camera shell by the camera shell, the metal sliding way, a camera pressing plate and a rear liquid crystal screen cover, the sliding way and the camera shell are embedded into a liquid crystal screen shell, and a stirring buckle on the back of the camera shell is stirred to unplug the camera out or press the camera into the camera shell for hiding, so privacy protection is ensured, and the overall attractive appearance of the telephone set may not be damaged; a high-resolution 800*4,807-inch 260,000-color digital liquid crystal screen makes more lifelike images and pictures and finer characters, and brings convenience to the input of a Chinese address book; address book content transmission between the telephone sets and between the telephone set and a server, three-way conferences, group conferences and video communication with a 3G mobile phone are supported; and convenience is brought to GK server management.

Description

technical field [0001] The invention is a business videophone with a hidden camera, which belongs to the technical field of video communication. technical background [0002] There is also no report on a commercial videophone with a hidden camera. [0003] The video coding technology of most videophones on the market is only H.261 and H.263 introduced by ITU-T, and our Ruixiu business videophone also adopts the latest video coding standard approved by ITU-T H.264, compared with H.263, H.264 has a flexible macroblock and block division method, and the motion estimation accuracy is further improved, and motion estimation with 1 / 4 or 1 / 8 pixel precision can be used. H.261 and H.263 adopt DCT transformation, while H.264 adopts an integer transformation similar to DCT. Under the same reconstructed image quality, the code rate of H.264 is 50% lower than that of H.263. While H.264 improves the encoding efficiency, the computational complexity is also greatly increased. The compu...
