Embodiment Construction

refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements. Also, the following detailed description does not limit the invention. Instead, the scope of the invention is defined by the appended claims and equivalents.

[0023] A personal multimedia device, as described herein, converts between different video standards to thus facilitate videoconferencing and other streaming video applications across different video transmission standards. The conversion can be performed using standard components of a personal multimedia device such as a set-top box and thus does not add additional cost to the set-top boxes.

Video Conference Overview

[0024] FIG. 1 is a diagram illustrating an exemplary video conferencing system 100. Users 101-1 through 101-N (collectively users 101) may use system 100 to videoconference with one another. Network 110 couples users 101 and 102 with one another. Video streams created by users 101 may be tr...

Abstract

Personal multimedia devices can detect when an incoming video format is different from a native format and make a local decision to convert incoming video formats to a format native to the personal multimedia device. The personal multimedia device may include a media processor that comprises an MPEG decoder / encoder, graphics processors, and a video decoder / encoder. These components increase a frame rate of a received video signal when the frame rate of the received video signal is less than a frame rate of the native video format of the personal multimedia device and decrease the frame rate of the received video signal when the frame rate of the received video signal is greater than the native frame rate of the set-top box. The graphics processor scales a frame resolution of the frames in the received video signal to correspond to the native video format.

Description

[0001] A. Field of the Invention[0002] The present invention relates generally to communications systems, and more particularly, to videoconferencing between entities that use multiple video standards.[0003] B. Description of Related Art[0004] Personal multimedia devices are devices that provide multimedia services to a user. Example of personal multimedia devices include set-top boxes and personal video recording (PVR) devices. A set-top box is a device that enables a television set to receive and decode digital television (DTV) broadcasts. Set-top boxes are frequently used to receive satellite and cable television signals. At a basic level, a set-top box will include an input connection for the television signal broadcast by the satellite or cable company, and an output connection leading to the user's television.[0005] Some set-top boxes additionally include more advanced features, such as a network port (e.g., Ethernet) and / or other input output connections, such as a keyboard o...
