Network nodes acquire bandwidth in contention-based networks for handling video traffic. A request to reserve a channel for transmission of a payload is sent prior to a network node receiving the payload. The payload is a burst of video data that is generated periodically. A network node determines a time period for reserving the channel. The network node determines when to initiate contending for the channel and the time period for transmitting the payload to another network node. A network node determines when a payload is expected to arrive and monitors its back off time period at least a time period prior to receiving a payload. The network node also monitors transmission of the payload and adjusts when to initiate contending for the channel.

Embodiments of apparatuses and methods to decrease a size of a memory in a low-latency video communication system are described. A control unit is configured to monitor a condition associated with at the communication link. The control unit is configured to receive the video content over a link based on monitoring. A memory comprising a full-frame buffer is coupled to the control unit. The full-frame buffer is configured as a history buffer to store a full frame of the video in a coding format that matches the coding format of the video content received over the link. A display unit is coupled to the history buffer. A portion of the full-frame buffer is configured as a network streaming buffer.
