Abstract: Exemplary embodiments of methods and apparatuses to project personal video recorder (“PVR”) trick mode operations over a network are described. A first content stream may be at a first speed. A request to access the first content stream at a second speed can be received. A second content stream can be generated based on a second speed. The second content stream can be send over a network to be rendered at the first speed by a client device. One or more anchor frames in the first content stream are selected. The second content stream is generated based on the one or more anchor frames. One or more dummy frames can be inserted into the second content stream. Indexing information can be generated to create a second content stream to send over the network.

Abstract: A method for synchronization of an audio stream and a video stream comprising the steps of (A) determining a first presentation time stamp from the video stream and generating a first handshake signal when the video stream is ready to be transmitted, (B) repeating and dropping one or more audio frames of the audio stream in response to the first handshake signal and a plurality of first predetermined threshold values until a second presentation time stamp from the audio stream matches the first presentation time stamp and generating a second handshake signal when the audio stream is ready to be transmitted and (C) transmitting the video stream and the audio stream in response to the second handshake signal.

Abstract: An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to generate a first composited data signal and a second composited signal in response to a first data signal having a first chroma format and a second data signal having a second chroma format. The second circuit may be configured to generate a first composited output signal having the first chroma format in response to the first and the second composited data signals.

Abstract: An apparatus comprising a de-interlacer circuit, a rate converter circuit and a zoom circuit. The de-interlacer circuit may be configured to generate a first progressive signal having a first rate in response to an interlaced signal. The rate converter circuit may be configured to generate a second progressive signal having a second rate in response to the first progressive signal. The zoom circuit may be configured to generate an output video signal in response to the second progressive signal. The output video signal may represent a portion of the second progressive signal having a frame size equal to a frame size of the interlaced signal.

Abstract: A method is provided for encoding K>1 sequentially presented video pictures. Each of the K pictures is divided into an m>1 row×n>1 column array of non-overlapping coding units of equal sizes. Each coding unit occupies a respective coding unit position in the picture from which it was divided. An arbitrary, pseudo random pattern of coding units is selected for refreshing during each of the K pictures. Each pattern selected during any given one of the K pictures includes a sequence of one or more coding units of the array. In addition, the pixels of each coding unit selected for refreshing during a kth picture occupy different pixel positions than each coding unit selected for refreshing during a preceding one of the 1st to (k?1)th pictures of the K pictures. Furthermore, each pixel position of a moving picture image formed from the K pictures is selected for refreshing once over the sequence of K pictures.
