Phase relationship control for control channel of a multimedia communication link

摘要

A multimedia system for data communications. A source device communicates over a full duplex control channel of a multimedia communication link using time domain multiplexed (TDM) frames having n time slots per frame. The source device allocates a first time slot position to a virtual channel for data transmission by the source device over the full duplex control channel. A sink device communicates over the full duplex control channel of the multimedia communication link. The sink device allocates a second time slot position to the virtual channel for data transmission by the sink device over the full duplex control channel. A timing of the second time slot position is offset from a timing of the first time slot position by substantially n/2 time slots.

1. A system for data communications, the system comprising:
a multimedia communication link having a full duplex control channel; a source device having:
a source translation layer supporting a half-duplex translation layer protocol; anda source link layer to communicate over the full duplex control channel of the multimedia communication link using time domain multiplexed (TDM) frames having n time slots per frame, the source device allocating a first time slot position to a virtual channel corresponding to the half-duplex translation layer protocol for data transmission by the source device over the full duplex control channel; and a sink device having:
a sink translation layer supporting the half-duplex translation layer protocol; anda sink link layer to communicate over the full duplex control channel of the multimedia communication link, the sink device allocating a second time slot position to the virtual channel corresponding to the half-duplex translation layer protocol for data transmission by the sink device over the full duplex control channel, a timing of the second time slot position being offset from a timing of the first time slot position by substantially n/2 time slots.
