Embodiment Construction

[0028] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any aspect described herein as "exemplary" is not necessarily construed as being preferred or advantageous over other aspects.

[0029] The described aspects and references to "one aspect", "an aspect", "an example aspect", etc. in this specification indicate that the described aspect may include specific features, structures, or characteristics, but each aspect may not necessarily include the A specific feature, structure, or characteristic. Furthermore, the phrases do not necessarily refer to the same aspect. In addition, when describing a particular feature, structure, or characteristic in combination with one aspect, it is considered that the realization of the feature, structure, or characteristic in combination with other aspects belongs to the knowledge of those skilled in the art, regardless of whether it is explicitly described.

Abstract

A packet structure for a Mobile Display Digital Interface (MDDI) includes a flexible sub-frame length to efficiently transmit large packets. A windowless video stream packet avoids repetitive transmissions of video packets when some parameters are unchanged, saving bandwidth. An enhanced reverse encapsulation packet combines the feature of a separate round trip delay packet with a separate reverse encapsulation packet. A link freeze is used to halt a transmission of a data stream at any point in the transmission and resume the transmission by a host.

Description

[0001] Claim priority according to 35U.S.C.§119 [0002] This patent application claims the priority of provisional application No. 60 / 928,488 filed on May 8, 2007, titled "VESA Standard Display Digital Interface Version 1.5", and said application The case is assigned to the assignee of the case and is hereby expressly incorporated into this article by reference.
