Objectives: In this work, the assessment of 3D video quality is performed with the HEVC (High Efficiency Video Coding) standard over a wireless transmission considering the diversity MIMO schemes. Methods/Statistical Analysis: The video sequences in both Multiview Extension and 3D-Extension with its depth map using the HEVC standard were encoded. In addition, three different diversity MIMO schemes and a turbo codec in the system were considered. The BER results obtained using the Montecarlo simulation for packet loss were implemented to evaluate the 3D video sequence at the output of the system, it based in the objective and subjective assessment. Findings: In 3D video encoding with multiple views using HEVC standard with GOP All-Intra coding structure, packets of different texture views can be lost, but in 3D video encoding with DIBR and depth data, you cannot miss any package of the texture views, because the video cannot be decoded. The coding structures of GOP type IPBB and IPPP is more susceptible to the package loss, so the transmission protocol TCP is the suitable. Therefore, this scheme in real- time transmission is not recommended. The increase of diversity in the MIMO schemes decreases the package loss, in this way, the increasing of the video quality that is verified using the objective assessment, but it with a cost of velocity transmission due that is required more intervals of transmission in the MIMO scheme i.e. (with redundant information). The packet loss in wireless transmissions with MIMO 3D video schemes encoded with HEVC standard it has greater impact on the degradation of the video sequences of high mobility than the low mobility. Application/Improvements: The assessment of 3D Video quality using the HEVC standard and its transmission through a wireless channel is using the diversity MIMO schemes which takes advantage of spatial dimension.
