Abstract

A digital device (100) for streaming audio and / or video data has a signal processor (111) configured to process blocks of samples of the audio and / or video data. The signal processor (111) requires a block processing time to respectively process a block of samples. The digital device (100) has an Audio Video Bridging interface (115) configured to generate and transmit frames which include the processed blocks of samples as payload. The Audio Video Bridging interface (115) is configured to set a transmit rate of the frames for at least one traffic class as a function of the block processing time.

Description

technical field [0001] Various embodiments relate to techniques for streaming audio and / or video data. Various embodiments relate to networks in which audio and / or video data is transmitted from one endpoint to another and to apparatus and methods for such networks. Background technique [0002] The increasing amount of data being transmitted over networks in the form of specific multimedia content has led to increased interest in ways to improve the quality and reliability of streaming data over virtual bridged local area networks. Audio Video Bridging (AVB) allows audio and / or video to be streamed over a LAN. Applications of AVB include streaming compressed and / or uncompressed audio and / or video data between multiple pieces of equipment. An exemplary transmission may include streaming uncompressed audio from an audio / video receiver to multiple networked speakers over Ethernet. AVB allows time-synchronized low-latency streaming services. [0003] Data transmitted using ...
