Abstract

The invention discloses a digital set-top box, comprises a microprocessing module; a sound acquisition module, an image acquisition module, a network module and a data display module connected with the microprocessing module, the network module comprising a transmitting unit and a receiving unit; and also comprises a conversion module connected with the sound acquisition module and the image acquisition module; a rate measurement module, wherein the conversion module and the micro-processing module are respectively connected with the rate measurement module. The microprocessing module comprises a compression unit, wherein the rate measurement module and the emission unit are respectively connected with the compression unit; and a decompression unit, the receiving unit and the data displaymodule are respectively connected with the decompression unit. The invention provides a digital set-top box with perfect connection between images and sounds and high synchronization rate when video chatting.

Description

technical field [0001] The invention relates to the technical field of set-top boxes, in particular to a digital set-top box. Background technique [0002] With the development of digital set-top box technology, the traditional high-quality TV-on-demand function has been difficult to meet the daily needs of users, and a better information interaction experience is an inevitable development trend. [0003] Video chat is the best medium for communication between people. The existing set-top box obtains video information through a camera device and a sound receiving device to generate an image and sound signal, and then compresses the sound signal and image image separately and transmits them through the network. When the above-mentioned transmission process is disturbed, the transmission rate of sound and image will be affected to varying degrees, so that the image and sound cannot be perfectly connected, which will cause the video chat image and sound to be out of sync. It c...
