Patent Searching and Data


Title:
送信装置および受信装置
Document Type and Number:
Japanese Patent JP5194110
Kind Code:
B2
Abstract:
In an audio and video transmission apparatus, a frequency division parameter control unit outputs a frequency division parameter Pt, Qt for relating a pixel clock (frequency: pclk) for video data with an audio clock (frequency: ft) for audio data. An audio/video/packet multiplexing unit converts audio data and the frequency division parameter Pt, Qt into packets, and superimposes the packets into blanking intervals of video data, thereby producing transmission data. The frequency division parameter Pt, Qt satisfies a relationship represented by: pclk/Pt=ft/Qt=fpt, and cause fpt to have a value that falls outside of a predetermined band that is determined as the band of audio data.
