Techniques are described for encoding an audio video stream that is transmitted over a network, for example a wireless or IP network, such that an entire frame of audio and an entire frame of video are transmitted simultaneously within a period required to render the audio video stream frames by an application in a receiver. Aspects of the techniques include receiving audio and video RTP streams and assigning an entire frame of RTP video data to communication channel packets that occupy the same period, or less, as the video frame rate. Also an entire frame of RTP audio data is assigned to communication channel packets that occupy the same period, or less, as the audio frame rate. The video and audio communication channel packets are transmitted simultaneously. Receiving and assigning RTP streams can be performed in a remote station, or a base station.
